No More Learning

' Hooke was a man of amazing
versatility, very self-confident, attacking problems in all branches
of science, greatly aiding their advance, but avid of fame.
In person but dispicable, being crooked and low in nature and as he grew
older more and more deformed. He was always very pale and lean and
latterly nothing but skin and bone 2.
His active, jealous mind conceived that almost every discovery of
his time had been there initiated; and this anxiety to claim ‘priority'
induced Newton to suppress his treatise Optics until after the date
of Hooke's death. His book Micrographia, 'a most excellent
piece, of which I am very proud,' as Pepys has it, is the record of
what a modern schoolboy newly introduced to the microscope would
write down. Yet he was undoubtedly, although not a lovable
character, the best 'mechanic of his age. '
British physiology, which had started magnificently with
Harvey, and had continued under Mayow, de Mayerne and others,
was carried forward by Stephen Hales, at one time fellow of
Corpus Christi college, Cambridge, and for years perpetual curate
at Teddington. He was a born experimenter, and, as a student,
worked in the 'elaboratory of Trinity College, which had been
established under the rule of Bentley, ever anxious to make his
college the leader in every kind of learning. Sachs has pointed
out that, during the eighteenth century, the study of the anatomy
of plants made but little progress ; but there was a very real

advance in our knowledge of plant physiology. This, in the main,
was due to Hales; he investigated the rate of transpiration and
held views as to the force causing the ascent of sap which have
recently come to their own; he recognised that the air might
be a source of food for the plant and connected the assimilative
function of leaves with the action of light,' though he failed to
find the mode of the interaction. He worked much on gases, and
paved the way for Priestley and others by devising methods of
collecting them over water. Hales, this 'poor, good, primitive
creature,' as Horace Walpole called him, was not less remarkable
as an investigator of animal physiology, and was the first to
measure the blood-pressure, and the rate of flow in the capillaries.
Sir Francis Darwin states:
In first opening the way to a correct appreciation of blood-pressure Hales'
work may rank second in importance to Harvey's in founding the modern
science of physiology.
He was, further, a man of 'many inventions,' especially in the fields
of ventilation and hygiene.
The beginning of our period coincides with the formation of
public museums. Previous to the Stewart times, collections of
‘natural objects' were, for the most part, housed in churches, in the
houses of the great, in coffee-houses and in the shops of apothe-
caries; but now public libraries were being established, and, in many
of these, botanical, geological and especially zoological specimens
found a home. In more than one Cambridge college, the library
still gives shelter to a skeleton, a relic of the time when anatomy
was taught within the college walls; and, at this day, the curious,
and, at times, inconvenient, yoke joining the museum at South
Kensington with the museum in Bloomsbury testifies to this
primitive state of affairs.
In 1728, John Woodward bequeathed his 'Fossils, a vast quan-
tities of Ores, Minerals and Shells, with other curiosities well
worth viewing' to Cambridge university; it was housed in the
university library and formed the nucleus about which the present
magnificent museum has collected. For many years, the Royal
Society maintained a museum which, at one time, contained 'the
stones taken out of Lord Belcarre's heart in a silver box,'. . .
‘a petrified fish, the skin of an antelope which died in St James'
Park, a petrified foetus' and 'a bottle full of stag's tears. ' The
trustees of Gresham college assigned the long gallery as a home
for these and other 'rarities'; but, when the society, in 1781,
migrated to Somerset house, the entire collection was handed over

to the British Museum. The charter of the last named is dated
1753, and its beginnings were the library of Sir Robert Cotton,
wbich the nation had purchased in 1700, and the collections of
Sir Hans Sloane, which were now purchased with the proceeds of
a lottery, set on foot for this purpose. The collections of this
General Repository,' as the act of 1753 called the museum, were
kept together until the middle of the nineteenth century, when,
after long delay, the natural history objects were transferred to
South Kensington and housed in a building which, in all respects,
was worthy of the Board of Works of the time.
John Tradescant and his son of the same name accumulated
and stored in south Lambeth a 'museum which was considered to
be the most extensive in Europe at that time. It was acquired in
1659 by Elias Ashmole, and, with his own collections, passed
by gift, twenty-three years later, to Oxford university, the whole
forming the nucleus of the present Ashmolean museum.
Want of space precludes the consideration of other museums;
but it may be remarked that the earlier collectors got together
their treasures much as schoolboys now collect, their taste was
universal and no rarity was too trivial for their notice. Such collec-
tions excited popular interest, and 'a museum of curiosities' was
often an added attraction to the London coffee-house. At the end of
the eighteenth century, the coffee-house part of the enterprise was
dropped, and the museum, with an entrance-fee and a priced cata-
logue, formed a source of revenue to many a collector, most
of whom were not too scrupulous in their identifications. The
dime museums in the Bowery, New York, are their modern
successors. These museums were of little scientific or educational
value ; at best, they stimulated the imagination of the uninformed,
or allowed a child to see with his own eyes something he had read
about in his books. The normal, as a rule, was passed by, the
abnormal treasured. Ethnographical objects were collected, not
so much to arouse in the spectator a desire to study seriously
‘y® beastlie devices of yo heathen' as to excite and startle him
with their rough unfinish, on the one hand, and their high finish
on the other. The collections of the museums were ill arranged,
inaccurately labelled and inaccessible to students; the staff
were wholly inadequate and mainly dependent for their living
on admission fees. It was not until the nineteenth century
was well advanced that a systematic and scientific attempt
was made to identify specimens accurately, to arrange them
logically, to label them fully and, further, to collect in the

background, unseen by the fleeting visitor, vast accumulations
of material for the investigation of the genuine student and
researcher.
Museums as centres of real education, not as places of wonder
and vacant amazement, are almost affairs of our time, and it
was not until the twentieth century that official guides were
appointed to explain their treasures to the enquiring visitor.
Even today, the system of weekly lectures on the contents of a
museum which obtains largely on the other side of the Atlantic
is, with us, only beginning.
We must not omit to mention the magnificent museum of the
Royal college of Surgeons, in London, which incorporates the
Hunterian collection brought together by John Hunter, and which
has been growing ever since his time. Of its kind, it is without a
rival in the world.
During the seventeenth century, men of science still, to a
great extent, remained the gifted amateurs they were at the time
of the foundation of the Royal Society; and yet they were very
successful in establishing many institutions which had a greater
effect on the advance of biological sciences than their founders
foresaw.
Towards the beginning of the seventeenth century, the Oxford
botanic garden had been founded (1621), which was followed, in
1667, by the opening of the Edinburgh botanic garden, and, in 1673,
by the foundation of the Chelsea physic garden, by the Apothe-
caries' company.
At the beginning of the eighteenth century,
Glasgow followed suit. By this time, many of the universities had
chairs of botany, and botany and anatomy were the first biological
sciences represented by professorial chairs in this country. In
1724, a chair was established at Cambridge, with Bradley as
its first professor ; but he and his immediate followers had little
success and, for the most part, were non-resident. Oxford
followed, in 1734, and Dillenius was the first to occupy the chair,
which had been founded by William Sherrard. The botanic
garden at Oxford, however, had been in existence for many years.
At Cambridge, it was not till 1759 that Walker founded the
botanic garden, which, at that time, occupied the northern site
of the present museums of science. The fine specimen of the
Sophora tree, the tree which yields the Chinese imperial yellow
dye, is the last and only memorial of this old botanic garden.
In 1765, Kew gardens, originally in possession of the Capel family,
were combined with Richmond gardens, then occupied by the

princess Augusta, widow of Frederick, prince of Wales. In fact,
this lady may be regarded as the foundress of Kew, which, since
her time, has played the leading part in the dissemination of
botanical knowledge throughout the world.
In the latter half of the eighteenth century, the Linnaean
system of classification had been generally adopted in Great
Britain, and, in the year 1783, Sir James Edward Smith secured,
from the mother of Linnaeus, for £1050, the entire Linnaean
collections. These did not, however, reach these islands without
an effort on the part of the Swedish government to retrieve
them. Indeed, it sent a man-of-war after the ship which
transported them.
Following on this acquisition, Smith, in 1788, founded the
Linnaean society, the immediate effect of which, perhaps, was
to bring about a revolution in the mode of publishing scien-
tific literature From the first, the Linnaean society issued
journals and transactions instead of books or treatises; their
publications took the form of memoirs read before the society.
In this respect, the Linnaean society set a fashion which has been
consistently followed by the numerous societies which since have
sprung up.
The Royal Society had taken all science as its province, and
nothing in natural history was alien to the activities of the
Linnaean society ; but, with the beginning of the nineteenth
century, societies began to spring up in the metropolis which
devoted their energies to the advancement of one science alone.
The earliest effort was that of the Royal Horticultural society,
founded in 1803. Its first secretary was Joseph Sabine, to whom
much of its earlier success was due. For a time, it undertook
the training of gardeners and also sent collectors to foreign
countries in search of horticultural rarities. It still does much
for horticulture, especially by its very successful flower-shows.
The Geological society of London was founded in 1807. It was
partly the outcome of a previous club known as the Askesian
society, and among the more prominent founders were William
Babington, Humphry Davy, George Greenough and others. The
meetings were at first held at the Freemasons' tavern. The
society, like many other learned societies, now has rooms at
Burlington house.
The Zoological society of London for the advancement of
zoology and animal physiology, and for the introduction of new
and curious subjects of the animal kingdom was founded in

1826 by Sir Stamford Raffles, the wellknown traveller and governor
in the east and the godfather of Rafflesia, J. Sabine, N. A. Vigors
and other eminent naturalists. It was incorporated by royal
charter in 1829.
The Royal Botanic society was founded in 1839, and was
granted an area of eighteen acres within the inner circle of
Regent's park, and here Marnock laid out the gardens very much
as they still are. Shortly after its establishment, annual exhi-
bitions or flower-shows were begun, and such exhibitions, not
entirely confined to flowers, are still one of the features of the
society.
Another society which has played a most useful part in the
promotion of science is the Cambridge Philosophical society,
founded in the year 1819, the only society outside the capital
towns which possesses a royal charter. About the same time,
the Dublin society (founded in 1731) assumed the title royal
The Edinburgh Royal society was founded in 1783; the date of its
revised charter is 1811. Many other societies in our chief towns
did much to advance the cause of science; but they are too
numerous to record here.
Another institution which embraced all branches of science was
the British Association for the Advancement of Science, which was
due largely to the enterprise of Brewster, Babbage and Herschel
It held its first meeting in York in the year 1831. The objects of
its founders were
to give a stronger impulse and a more systematic direction to scientifie
enquiry, to promote the intercourse of those who cultivate science in different
parts of the British Empire with one another, and with foreign philosophers,
to obtain a more general attention the objects of science, and the removal
of any disadvantages of a public kind, which impede its progress.
With certain exceptions, the books on biology during the last
half of the eighteenth century and the beginning of the nineteenth,
were largely treatises on classification, or on the practical applica-
tion of the knowledge of plants, such as medical and agricultural
works. It was during this period, too, that certain magazines
were started. Curtis founded The Botanical Magazine in the
year 1787. But the great increase of scientific journals only
began some fifty years later; many of those dealing with different
branches of biological science were first published about the
middle of the nineteenth century. Among them may be men-
tioned the following, with the date of their first appearance:
The Annals and Magazine of Natural History, 1841 ; The

VIII] Scientific Journals and Exploration 289
Zoologist, 1843 ; Quarterly Journal of Microscopical Science,
1853; The Journal of Horticulture, 1862; The Geological
Magazine, 1864; The Journal of Anatomy and Physiology,
1866.
Great advance was also being made in our knowledge of the
flora and fauna of the British dominions beyond the seas. Pro-
minent among explorers was Sir Joseph Banks, who studied the
flora of Newfoundland in 1766 and, later, accompanied by Solander
and others, started with Cook on his memorable voyage round
the world in the 'Endeavour. ' He returned to England in
1771 and, during the following year, visited Iceland. Banks's
very extensive explorations helped to make Kew the centre of
botanical activity, an activity which soon became world-wide.
It is worth recalling that his private secretary was the dis-
tinguished botanist Robert Brown, to whom he bequeathed his
herbarium and library. Brown took part in the celebrated expe-
dition of Flinders to Australia, which started in 1801, and added
greatly to our knowledge of the fauna and flora of Australasia.
Nor must it be forgotten that Brown was the first to observe the
cell-nucleus. This, as one of his biographers remarks, was a
triumph of genius,' for Brown worked only with the simple
microscope, and the technique of staining cells and tissues was
then unknown. It is interesting to note that the nucleus was
described and figured eight years before the surrounding proto-
plasm attracted attention. In fact, in the early part of the
nineteenth century, repeated improvements in the microscope
and in histological technique were demonstrating very clearly that
all living organisms, whether plant or animal, consist either of
a single cell or a complex of cells, and that they all began life
as a single cellular unit.
At the beginning of the nineteenth century, men of science
specialised less than now. Each branch of science was smaller,
and more than one branch could be grasped and studied by
the same observer. Among such men were J. S. Henslow and
Adam Sedgwick, the prime movers in the founding of the Cam-
bridge Philosophical society. Henslow, at first, devoted especial
attention to conchology, entomology and geology. He was a
professor of mineralogy at twenty-six, and with that power of
quick change of chair, once more prevalent than now, he became
professor of botany the following year. He was succeeded
in the chair of mineralogy by Whewell, which recalls the fact
that Whewell's History of the Inductive Sciences, one of the
19

The Literature of Science
wellknown Bridgewater treatises, played a large part in the
thought of our great-grandparents. Henslow was among the
first to insist upon practical work in his botanical classes. His
class dissected living plants, and investigated and recorded such
structure as they could make out. He provided them with
proper apparatus for dissections, and he saw that they studied
the physiology and the minute anatomy of plants as well as
external features.
Another striking feature of the British botanists of a hundred
years ago was their determined and steady effort to replace the
artificial Linnaean system by a more natural one. Prominent
among the men who gradually evolved a sounder view of the
interrelationship of plants were the elder Hooker, Robert Brown,
Sir Joseph Banks (“the greatest Englishman of his time'), Bentham
and, especially, John Lindley. Lindley was professor at the newly-
founded university college in Gower street; and this institution
took a very prominent part in the science of the century, being
untrammelled by restrictions which sorely retarded the advance-
ment of science at the older universities.
Plant pathology was, also, coming to the fore, and Miles
Joseph Berkeley was establishing a permanent reputation as a
systematic mycologist. He has, indeed, been called the origi-
nator and founder of plant pathology, and was the first to
recognise the economic importance of many fungoid plant
diseases. His work on Phytophthora infestans—the potato fungus
-(1846) is still a classic.
Another branch of science, of less economic but of more
academic interest, was plant palaeontology, which, under Witham,
Binney and Williamson—the last named was elected, in 1851,
professor of natural history, anatomy and physiology at the
newly-founded Owens college, Manchester—was rapidly forging
ahead, at any rate in the north of England. Here, chiefly, the
foundations were being laid for the very remarkable advances
which have been made in this branch of the subject since the
last quarter of the nineteenth century.
Modern geology, in Great Britain, might be said to begin with
James Hutton, who, after taking the degree of doctor of medicine
at Leyden, devoted himself to the cultivation of a small estate,
inherited from his father, and to practical chemistry. The lucrative
results of the latter employment enabled him to give himself up
wholly to scientific pursuits. His agricultural studies, especially
during his residence with a farmer in Norfolk, interested him in

the various sediments deposited either by rivers or seas, and he
recognised that much of the present land had once been below
the sea. But he also investigated the movements of strata and the
origin of igneous rocks, and especially the nature and relations
of granite. The great and distinctive feature of Hutton's work
in geology is the strictly inductive method applied throughout.
He maintained that the great masses of the earth are the same
everywhere. He saw no occasion to have recourse to the
agency of any preternatural cause in explaining what actually
occurs,' and he remarks that, the result therefore of our present
enquiry is, that we find no vestige of a beginning—no prospect
of an end. '
John Playfair, a pupil and friend of Hutton, issued, in 1802,
a volume entitled Iustrations of the Huttonian Theory of the
Earth. Playfair, to quote Sir A. Geikie's words, was 'gifted with
a clear penetrating mind, a rare faculty of orderly logical arrange-
ment, and an English style of altogether remarkable precision and
elegance. ' He was an able exponent of his master's views and
capable of adding many observations and contributions of his own
to his convincing sketch of the Huttonian theory.
William Smith, whom Sedgwick called the 'father of English
Geology,' became interested in the structure of the earth's crust,
at first, from a land-surveyor's and engineer's point of view. He
was one of the earliest to recognise that each of the strata he
studied carefully contains animal and plant fossils peculiar to
itself, by which it can be identified. In 1815, he published his
geological map of England and Wales; and, between 1794 and
1821, he issued separate geological maps of many English counties.
Further he is responsible for introducing many terms—'arbitrary
and somewhat uncouth,' as Sedgwick remarked-which have
become the verbal currency of British geology.
Adam Sedgwick, whose personality made a deep impression
on his university, was appointed Woodwardian professor of
geology in 1818, and threw himself, with surprising vigour, into a
subject which, to him, at that time, was almost new.
He was
great as a teacher and as an exponent of his science, being gifted
with eloquence, and, as founder of the Sedgwick museum, he
greatly enlarged the collection got together by John Woodward,
who established the professorship. From 1819 to 1823, he worked
chiefly in the south and east of England ; then, he turned his
attention to Lake-land and, afterwards, in 1827, to Scotland (with
Murchison). In 1829, he went abroad with Murchison, visiting
19-2

parts of Germany and the eastern Alps, the result being an
important joint paper on the latter (1829-30). In the long vaca-
tion of 1831, he attacked the problem of the ancient rocks in the
northern part of Wales, which, owing to the absence of good
maps or easy communication, the complicated structure of the
country and the frequent rarity or imperfect preservation of its
fossils, presented exceptional difficulties. In that and the follow-
ing summer (as well as in some later visits), he ascertained the
general succession of the rocks from the base of the Cambrian to
the top of the Bala, or of the whole series afterwards called Cam-
brian and lower Silurian (more recently Ordovician). Laborious
fieldwork became more difficult after an illness in 1839; but he
continued to extend and publish the results of his investigations
in Wales, in the Lake district and in the Permo-Triassic strata
of north-eastern England. Though he was a liberal in politics,
his inclinations as a geologist were conservative.
George Julius Poulett Scrope, by his studies of volcanic dis-
tricts in Italy, Sicily and Germany, and especially by his memoir
on the volcanoes of central France, and by his observations on the
erosion of valleys by rivers, did much to extend and confirm the
views of Hutton and Playfair. His remarks, also, on the lamination
and cleavage of rocks were highly suggestive; in fact, but for the
interruptions of politics, he would have hardly fallen behind his
friend Charles Lyell.
During the first half of the nineteenth century, the belief in a
universal deluge was widely held by geologists. William Buckland,
in his Reliquiae Diluvianae (1823), supported his belief by his
'Observations on the Organic Remains contained in Caves, Fissures
and Diluvial Gravel. ' But, both he and Sedgwick, without giving
up the view of a universal flood, abandoned, to some extent, the
evidence on which, at one time, they had based their belief.
Another geologist of great eminence was H. T. de la Beche,
whose ancestors really did come over with the Normang. His
Geological Manual was spoken of, at the time, as the best work of
its kind which had appeared in our country; and his Report on the
Geology of Cornwall, Devon and West Somerset (1839) is a
masterly production. He occupied himself for a long time in
a
making a geological survey of parts of Devon and Dorset on
one-inch ordnance maps, and was appointed, in 1832, by govern-
ment to conduct the geological survey of England, in which posi-
tion he superintended the erection of the Jermyn street museum.
The interest of (Sir) Charles Lyell in geology was aroused by

a
the fascinating lectures of Buckland. He was trained, at first, for
the law; but his legal studies were arrested by a weakness in his
eyes, which, for a considerable time, prevented any continuous
reading, and troubled him more or less throughout life. But this
enforced rest enabled him to devote himself to geology, and, in
1824, he began systematic travel for that purpose. About 1827,
his future book—The Principles of Geology-began to take a
definite shape in his mind. In the spring of that year, with the
Murchisons, he visited Auvergne, passing to the south of France and
to the north of Italy as far as the Vicentine and the Euganean hills.
Thence he went to Naples and Sicily, studying not only their
volcanic districts, but, also, the tertiary fossils of other parts of
Italy, returning to London after an absence of more than three-
quarters of a year. The first volume of The Principles appeared
in 1831, while he was travelling in France and studying the extinct
volcanoes of Olot in Spain, the second volume early in 1832 and
the third in 1833. At a later date, the book was divided, the first
two volumes retaining the title Principles, and the third appearing,
in 1838, as The Elements of Geology. During these years, he con-
tinued his studies of European geology, extending his journeys to
Denmark and Scandinavia. In 1841, he began a twelvemonth's
journey in Canada and North America, an account of which is
given in Travels in North America, published early in 1845. The
same year he revisited that continent, making a much more
extended journey in the United States, which is recounted in his
Second Visit etc. , published in 1849. He returned, for shorter visits,
in 1852 and 1853, and, in 1854, went to Madeira and the Canary
islands. During the years between 1842 and 1859, he continued
his work in various parts of Europe, and, in the latter year,
appeared Darwin's Origin of Species. The study of this book
completed Lyell's conversion to the views expressed by Darwin',
and he also investigated the evidence in favour of the early
existence of man.
The results of these studies, with an account of the glacial
epoch, form the 'trilogy' entitled The Antiquity of Man, which
appeared early in 1863. After this time, his journeys, necessarily,
,
became shorter, though his interest in geology continued to be
as keen as ever, till, after a period of increasing weakness, he
died in February 1873.
Henry Clifton Sorby made his mark in more than one depart-
ment of science, to which a sufficiency of income enabled him to

devote his life ; but he will always be remembered as the father
of microscopic petrology. Thin slices of hard bodies had already
been made for examination under the microscope; but Sorby was
the first to perceive the value of this method for the examination
of rocks in general. In 1849, he made the first transparent section
of one with his own hands, publishing his first petrographical
study in 1851. In a few years, his example had been followed
both in England and in other countries, and the result has been
a vast increase in our knowledge of the mineral composition
and structures of rocks, and of many difficult problems in their
history.
Sir Roderick Impey Murchison was descended from a well-
known Scottish clan living in Ross-shire. He was brought up in
the army and took part in several of the engagements under
Wellesley in Portugal and Moore in Galicia. He was a man of means,
and having, at an early date, retired from the army, he occupied
himself at first with the active sports of a country gentleman. But,
his attention having been turned to science by Sir Humphry Davy,
he very soon became an eager and enthusiastic geologist. At first,
he especially devoted himself to the rocks of Sussex, Hants and
Surrey. Later, he explored the volcanic regions of Auvergne
and other parts of France, and of Italy, the Tyrol and Switzerland,
and, together with Sedgwick, published much on the geology of
the Alps.
But it was not till 1831 that Murchison began his real
life's work, which was a definite enquiry into the stratification of
the rocks on the border of Wales. The result of his labours,
published in 1839, was the establishment of the Silurian system
and the record of strata older than and different from any that had
hitherto been described in these islands. In 1837, he and Sedgwick,
by their work in the south-west of England and the Rhineland,
established the Devonian system; and, in 1840, he extended his
investigations from Germany to Russia. In the following year, at
the desire of the Tsar, he travelled over a considerable part of
that country as far as the Ural mountains on the east and the sea
of Azov on the south. In 1855, he was appointed director general
of the geological survey and director of the museum in Jermyn
street, in both of which posts he succeeded Sir Henry de la Beche.
Towards the end of his life, he founded a chair of geology and
mineralogy at Edinburgh.
William Buckland was, perhaps, better known as a teacher
and as an exponent of his science than for any very outstanding
original investigation carried on by him in geology. Unlike

Sedgwick, however, he had made a systematic study of his subject
before he was appointed, in 1813, reader of mineralogy at Oxford.
In this post, he so aroused the interest of his students that a
readership in geology was specially endowed by the Treasury six
years later, of which he was the first holder. He was a man of
many accomplishments, and he by no means confined his attention
to geology. He entered with great zest into many practical
questions of the day, especially such as affected agriculture and
sanitary science. In 1845, he was appointed dean of Westminster,
and, shortly after this, his health began to decline.
We have mentioned above that men of science were less
specialised at the earlier part of our period than they have now
become. It is a peculiar feature of British science that many of
its most successful researchers were amateurs-gifted not only
with brains but with wealth. Many of those whose names we
mention held no kind of professional or academic posts. Even
the holding of professorial chairs in the earlier part of the nine-
teenth century usually involved teaching in more than one science.
To the year 1866, the professor of anatomy at Cambridge was
responsible for the teaching of zoology as well as for that of
anatomy. In many other places, the professorship of zoology was
responsible for what teaching there was in animal physiology, and,
in the London hospitals, strictly scientific subjects were then
taught by doctors in practice who were on the staff of the hospital.
It was not till the year 1883 that Michael Foster was appointed to
the professorship of physiology at Cambridge, though, as praelector
in that subject at Trinity college, he had been building up a great
physiological school for several years.
On the zoological side, one of the most productive morpho-
logical anatomists of the nineteenth century was Richard Owen,
Hunterian professor and, later, conservator of the museum of the
Royal college of Surgeons. In 1856, he became superintendent
of the natural history branch of the British Museum, and this post
he held until 1884. He added greatly to our knowledge of animal
structure by his successful dissection of many rare forms, such as
the pearly nautilus, limulus, lingula, apteryx and others, and,
following on the lines of Cuvier, he was particularly successful in
reconstructing extinct vertebrates. Another considerable advance
he made in science was the introduction of the terms 'homologous'
and 'analogous. ' His successor in both his posts, Sir William
Flower, an authority on cetacea and on mammals in general, took
an active part in arranging the contents of the museums under his

charge in such a way as to teach the intelligent public a lesson in
morphology and classification.
Throughout the century, repeated attempts had been made to
classify the members of the animal kingdom on a natural basis,
but, until their anatomy and, indeed, their embryology had been
sufficiently explored, these attempts proved somewhat vain. As
late as 1869, Huxley classified sponges with Protozoa, Echino-
derms with Scolecida and Tunicates with Polyzoa and Brachio-
poda. By the middle of the century, much work had been
done in sorting out the animal kingdom on a natural basis, and
Vaughan Thompson had already shown that Flustra was not
a hydroid, but a member of a new group which he named
Polyzoa. Although hardly remembered now, he demonstrated,
by tracing their development, that Cirripedia are not molluscs ;
he established the fact that they began life as free-swimming
Crustacea; he, again, it was who showed that Pentacrinus is
the larval form of the feather-star, Antedon.
Among marine biologists of eminence was Edward Forbes,
who was the first to investigate the distribution of marine
organisms at various depths in the sea; and he it was who de-
fined the areas associated with the bathymetrical distribution of
marine life, and pointed out that, as we descend into depths below
fifty fathoms, vegetable life tends to fade away and that aquatic
organisms become more and more modified.
The custom of naturalists to go on long voyages was still main-
tained. The younger Hooker accompanied Sir James Ross in the
'Erebus' on his voyage in search of the south magnetic pole; Huxley
sailed on the Rattlesnake' with Owen Stanley, and, on this voyage,
laid the foundation of his remarkable knowledge of the structure
of marine animals; Darwin sailed on the ‘Beagle' (1831—6) and,
among the many results of this memorable voyage, was his theory
of the structure and origin of coral-reefs. The invention of
telegraphy indirectly brought about a great advance in our know-
ledge of deep-sea fauna. It was necessary to survey the routes
upon which the large oceanic cables were to be laid, and, by the
inventions of new sounding and dredging instruments, it was
becoming possible to secure samples of the bottom fauna as well
as of the sub-stratum upon which it existed.
Other names
that occur in connection with deep-sea dredging are those of
Sir Wyville Thomson, of W. B. Carpenter and of J. Gwyn Jeffreys.
But by far the most important and, up to the present time,
unrivalled attempt to solve the mysteries of the seas was that of

H. M. S. 'Challenger,' which was despatched by the admiralty at
the close of the year 1872, the results of whose voyage have
appeared in some eighty quarto volumes. The results of the
exploration of the sea by the Challenger' have never been
equalled. In one respect, however, they were disappointing. It
had been hoped that, in the deeper abysms of the sea, creatures
whom we only know as geological, fossilised, bony specimens,
might be found in the flesh; but, with one or two exceptions-
and these of no great importance—such were not found. Neither
did any new type of organism appear. Nothing, in fact, was
dredged from the depths or found in the tow-net that did not fit
into the larger groups which already had been established before
the 'Challenger' was thought of. On the other hand, many new
methods of research were developed during this voyage, and
with it will ever be associated the names of Wyville Thomson,
mentioned above, Moseley, John Murray and others who, happily,
are still with us.
During the nineteenth century, many other expeditions left
Great Britain to explore the natural history of the world, some
the result of public, some of private, enterprise. They are too
numerous to mention. But a word must be said about the
wonderful exploration of central America which has just been com-
pleted, under the auspices of F. D. Goodman and 0. Salvin. The
results are incorporated in a series of magnificently illustrated
quarto volumes which have been issued during the last thirty-six
years. Fifty-two of these relate to zoology, five to botany and
six to archaeology. Nearly forty thousand species of animals
have been described, of which about twenty thousand are new,
and nearly twelve thousand species of plants. There are few
remote and partially civilised areas of the world whose zoology
and botany are on so secure a basis, and this is entirely owing
to the munificence and enterprise of the above mentioned men of
science.
With regard to our own shores, one of the features of the
latter part of the nineteenth century has been the establishment
of marine biological stations, the largest of which is that of the
Marine Biological association at Plymouth. The Gatty laboratory
at St Andrews, the laboratories at port Erin in the isle of Man,
and at Cullercoats, have, also, for many years, being doing ad-
mirable work. All these establishments have devoted much
technical skill and time to solve fishery and other economical
problems connected with our seas.

By far the most important event in the history of biology in
the nineteenth century was the publication, in 1859, of The Origin
of Species. This statement might be strengthened, for the publi-
cation of this book changed the whole trend of thought not only
in biology, not only in other sciences, but in the whole intellectual
outlook of the world. There were, of course, many British
evolutionists before Darwin, amongst whom may be mentioned
Charles Darwin's grandfather, Erasmus Darwin, Wells, Patrick
Matthew, Pritchard, Grant, Herbert-some of these writers even
hinted at natural selection. Above all, Robert Chambers, whose
Vestiges of Creation remained anonymous until after his death,
strongly pressed the view that new species of animals were being
evolved from simpler types.
During the incubatory period of Darwin's great work, as Alfred
Newton has remarked, systematists, both in zoology and botany,
had been feeling great searchings of heart as to the immutability
of species. There was a general feeling in the air that some light
on this subject would shortly appear. As a recent writer has
reminded us,
In studying the history of Evolutionary ideas, it is necessary to keep in
mind that there are two perfectly distinct lines of thought. . . . First. The
conviction that species are not immutable, but that, by some means or other,
new forms of life are derived from pre-existing ones. Secondly. The con-
ception of some process or processes, by which this change of old forms into
new ones may be explained 1.
Now, as we have seen, the first of these lines of thought had been
accepted by many writers. Darwin's great merit was that he
conceived a process by means of which this evolution in the
ganic kingdom could be explained.
After his return from the voyage in the ‘Beagle,' and after a
short residence in London, Darwin, in 1842, settled at the village
of Down in Kent, and here it was, he says, 'I can remember the
very spot on the road, whilst in my carriage, when to my joy the
solution occurred to me. ' The 'solution' was natural selection
'
by means of the survival of the fittest. ' Darwin had written out
his views so early as 1842, but he had confided them only to
a few, and were it not for a strange coincidence, they might have
remained in manuscript even later than 1858.
For, in the spring of 1858, Alfred Russel Wallace, a traveller
and explorer who made his living as a collector, was lying
sick of fever at Ternate, and his thoughts turned, as Darwin's
had done years before, to the writings of Malthus? , of Jesus

college, Cambridge. The idea of natural selection flashed across
his mind. He lost no time in setting it down in writing and in
sending it to Darwin by the next post. The story is too well
known to repeat here with what mutual magnanimity Wallace and
Darwin behaved. Each always gave the other the fullest credit
of the inspiration.
The publication of The Origin of Species naturally aroused
immense opposition and heated controversy. But Darwin was no
controversialist. Patient and entirely unresponsive under abuse,
he was, at the same time, eager for criticism (knowing that it might
,
advance the truth). His views offended, not only old-fashioned
naturalists, but theologians and clerics. Huxley wrote shortly
after Darwin's death,
None have fought better, and none have been more fortunate, than Charles
Darwin. He found a great truth trodden underfoot, reviled by bigots, and
ridiculed by all the world; he lived long enough to see it, chiefly by his own
efforts, irrefragably established in science, inseparably incorporated with the
common thoughts of men, and only hated and feared by those who would
revile, but dare not. What shall a man desire more than this 1 ?
Darwin, also, was fortunate in his supporters, though some of
the leading biologists of the time conspicuous among them was
Owen-rejected the new doctrine. In Hooker, on the botanical side,
in Huxley, on the zoological side, and in Lyell, on the geological
side, he found three of the ablest intellects of his country and
of his century as champions. None of these agreed on all points
with his leader; but all three gave a more than general adherence to
his principles and a more than generous aid in promulgating his
doctrine. Lyell was an older man, and his Principles of Geology
had long been a classic. This book inspired students destined to
become leaders in the revolution of thought which was taking
place in the last half of the nineteenth century. One of these
writes :
Were I to assert that if the Principles of Geology had not been written,
we should never have had the Origin of Species, I think I should not be going
too far: at all events, I can safely assert, from several conversations I had
with Darwin, that he would have most unhesitatingly agreed in that opinions.
Sir Joseph Hooker, whose great experience as a traveller and a
systematic botanist, and one who had in his time the widest know-
ledge of the distribution of plants, was of invaluable assistance to
Darwin on the botanical side of his researches. Those who

remember Hooker will remember him as a man of ripe ex-
perience, sound judgment and a very evenly balanced mind. But
all these high and by no means common qualities were combined
with caution, and with a critical faculty which was quite invaluable
to Darwin at this juncture. Huxley was of a somewhat different
temperament. He was rather proud of the fact that he was
named after the doubting apostle; but, whatever Huxley doubted,
he never doubted himself. He had clear-cut ideas which he was
capable of expressing in the most vigorous and the most culti-
vated English. Both on platform and on paper he was a keen
controversialist. He contributed much to our knowledge of
morphology. But never could he have been mistaken for a
field-naturalist. In the latter part of his life he was drawn away
from pure science by the demands of public duty, and he was,
undoubtedly, a power in the scientific world. For he was ever
one of that small band in England who united scientific accuracy
and scientific training with influence on the political and official
life of the country.
It is somewhat curious that the immediate effect of the publi-
cation of The Origin of Species and of the acceptance of its
theories by a considerable and ever-increasing number of experts
did not lead to the progress of research along the precise lines
Darwin himself had followed. To trace the origin of animals and
plants and their interconnection was still the object of zoologists
and' botanists, but the more active researchers of the last part
of the nineteenth century attacked the problem from standpoints
in the main other than that of Darwin. The accurate description
of bodily structure and the anatomical comparison of the various
organs was the subject of one school of investigators : Rolleston's
Forms of Animal Life, re-edited by Hatchett Jackson, Huxley's
Vertebrate and Invertebrate Zoologies, and Milnes Marshall's
Practical Zoology testify to this. Another school took up with
great enthusiasm the investigation of animal embryology, the
finest output of which was Balfour's Text-book of Embryology,
published in 1880. Francis Maitland Balfour occupied a chair,
especially created for him at Cambridge university, in 1882,
and, for a time, Cambridge became a centre for this study, and
Balfour's pupil, Sedgwick, carried on the tradition. Members of
yet another school devoted themselves to the minute structure
of the cell and to the various changes which the nucleus under-
goes during cell-division. Animal histology has, however, been
chiefly associated with physiology; and, as this chapter is already

greatly overweighted, we have had to leave physiology on one
side. The subjects of degeneration, as shown by such forms as
the sessile tunicata, the parasitic crustacea and many internal
parasitic worms, with the last of which the name of Cobbold
is associated, also received attention, and increased interest was
shown in the pathogenic influence of internal parasites upon
their hosts.
Towards the end of our period, a number of new schools of
biological thought arose. As Judd tells us :
Mutationism, Mendelism, Weismannism, Neo-Lamarckism, Biometrics,
Eugenics and what not are being diligently exploited. But all of these
vigorous growths have their real roots in Darwinism. If we study Darwin's
correspondence, and the successive essays in which he embodied his views at
different periods, we shall find, variation by mutation (or per saltum), the
influence of environment, the question of the inheritance of acquired
characters and similar problems were constantly present to Darwin's ever
open mind, his views upon them changing from time to time, as fresh facts
were gathered.
Like everything else, these new theories are deeply rooted in
the past.

CHAPTER IX
ANGLO-IRISH LITERATURE
THE early classical culture of Ireland, her literary technique
in her native Gaelic and the equipment of solid learning that
enabled her missionaries to evangelise much of western Europe,
have always been a source of puzzled surprise to the modern
historian.
Only quite recently has the veil been lifted from this perplexing
historical problem. For Zimmer has proved that the remarkable
early Irish erudition was due to an exodus of Gaulish scholars
into Ireland owing to the devastation of their country by the
Huns, Vandals, Goths and Alans. They avoided England, which,
at the time, was suffering from continental invasions; they sought
Ireland because it was known, through the traders plying between
the mouths of the Loire and Garonne and the south and east
coasts of Ireland, to be not only a fertile and prosperous country
but, also, to be already favourable to the Christian religion. Two
circumstances conspired to establish the success of the influx of
Gaulish scholars and divines with their precious manuscripts. For
they reached Ireland with a learning that, as has been said,
was still to the full extent the best tradition of scholarship in Latin Grammar,
Oratory and Poetry, together with a certain knowledge of Greek-in fact
the full classical lore of the 4th Century.
They arrived, also, at a time when the Irish were most ready to
receive them. For they found native schools of Irish oratory and
poetry in which their Brehons or jurists and Filidh (Filé) or poets
were being laboriously trained. To use Bede's expression, it was
not book-Latin but a living speech and a literature in the making
that was now heard in many parts of Ireland. '
No wonder, then, that a fusion of Gaelic and classical literature
began to take place. Thus, Irish bards fell into the metres of
Latin hymns sung in the churches, and introduced final and
internal rime, and a regularly recurring number of syllables, into

303
their native poetry from the Latin; though Sigerson and others
would have us believe that rime came into Latin from the Gaels
or their kinsmen the Gauls, and that Cicero's famous O fortunatam
natam me Consule Romam shows this Celtic influence on Latin
poetry. Moreover, there was drawn into the Gaelic tongue a form
of rhythmic prose to be found in very early Gaelic writings,
notably the incantation of Amorgen, known as rosg, which still
has its counterpart in the Welsh preachers' hwel or rhetorical
cadence.
So complete a removal, westward, of classical scholarship
was thus made in the fourth century that, at the end of the fifth
century, Sidonius Apollinaris declares that he knew of but one
scholar at Trèves, Argogastis, who could speak and write pure
Latin. But the lucky Irish, all this while, were enjoying the full
gift of classical learning, and that at a time before scruples had
arisen in the minds of professors of Christianity against the study
of classics, owing to the pagan doctrines which pervaded them.
They, therefore, gave themselves up whole-heartedly to it, and when,
as missionaries and scholars, they carried back this classical
learning to the continent at the end of the fifth century, they
were amazed to find that they and their fellow-countrymen were
almost its sole possessors.
The interfusion of the Gaulish classical and Christian and the
Gaelic schools of literature, thus early in Irish history, not only
made for a singular forbearance towards such pagan themes as are
to be found in The Colloquy of St Patrick with Oisin (Ossian),
but, also, gave to the religious poems of the Irish saints and the
curiously free Gaelic translations from Vergil and other classical
writings a picturesque individuality which makes them delightful
reading.
Gaelic poetry resolves itself roughly into fairy poetry or
pagan supernatural poetry, early and later religious poetry, nature
poetry, war poetry, love poetry and what may be termed official
poetry, i. e. that of the bards as court poets, and as poets
attached to the great chieftains whose exploits and nuptials they
celebrated and whose dirges they sang; while, here and there,
specimens of Irish satirical poetry are to be met throughout the
three periods of ancient, middle and later Irish, into which
leading scholars are agreed in dividing the works left to us in
Irish Gaelic.
The early war poetry does not call for special comment beyond
this; as
as was to have been expected, it largely consists of

laudations of chieftains of a fiercely barbaric kind, and abounds with
picturesque descriptive phraseology. Thus, in Deirdre's Lament
over the Sons of Usnagh, they are variously described as 'three lions
from the Hill of the Cave,' 'three dragons of Dun Monidh' and
three props of the battle-host of Coolney. ' But, running through
the savage and demonic incidents that characterise the early
Irish epics, there is a vein of generosity of one heroic combatant
towards another, the desire to fight fair and even to succour
a failing enemy, strangely anticipatory of the spirit of medieval
chivalry.
Of official poetry, it may be said that its technique is extremely
elaborate and, since it was necessary to put as much thought as
possible into each self-contained quatrain, its condensations often
make very hard sayings of these early ranns. A love of, or
tendency towards, the supernatural permeates early and middle
Irish poetry, as, indeed, it also pervades The History of Ireland
by Geoffrey Keating, the Irish Herodotus, who wrote as late as
1634; and much of the fascination of Gaelic verse is due to the
intrusion of the glamour of the other world' into its pages.
Love poetry, among the earliest of its kind in Europe, not
only finds poignant expression in such an early Irish poem as What
is Love? -an expression as definite in its description of the
sufferings of a lover as can be found even in Shakespeare's Sonnets
a
- but the love lyrics interspersed among Irish prose romances are
generally uttered by famous women whose adventures are there
described with a passionate purity and tender, delicate feeling
rarely met with in the heroines of the Arthurian cycles.
One other characteristic distinguishes old Gaelic poetry from
that of contemporary European writers—that love of nature
described by Matthew Arnold as natural magic and, according
to him, specially characteristic of early and medieval Irish and
Welsh poetry. This feature of Gaelic poetry is not only to be
noticed in the open air Fenian Sagas, but, even in an early hymn
to the Virgin, we find her described as:
Branch of Jesse's Tree, whose blossoms
Scent the heavenly hazel wood!
and
Star of knowledge, rare and noble,
Tree of many blossoming sprays!
Indeed, the love of nature suffuses all Irish Gaelic poetry.
The bard of early days felt it even among the icy rigours of winter,
while the cheerful companionship with nature of the Irish monk

Translations from Irish Poetry

or anchorite is in marked contrast with the fakir-like indifference
to her influences of a St Simeon Stylites or the voluntary with-
drawal from them of the enclosed Orders of later days. Enough
has been said here to suggest that there is much in Irish Gaelic
literature, which, if well translated into English verse or prose,
might have a stimulative effect upon English letters. Stopford
Brooke set himself to prove this by an instructive essay entitled
The Need and Use of getting Irish Literature into the English
Tongue, written three and twenty years ago, in which he showed
that there is a vast body of that literature untranslated or in-
adequately translated, and that very much of it, in good hands,
might be so rendered as to prove a substantial gain to English
literature.
There has been a considerable response to his appeal, and it
is not a little remarkable that, more than a hundred years ago,
an early scion of the same literary stock, Charlotte Brooke, daughter
of Henry Brooke, the dramatist, had conceived the same view of
the importance of recruiting English literature from Irish Gaelic
sources, and put it into practice by her own volume of translations
from Irish poetry.
Unfortunately, however, the artificial, not to say affected,
English verse of her day was about the worst vehicle for the
reproduction of the best Gaelic poetry, and the contributors to
Hardiman's Irish Minstrelsy, which followed her volume, and even
later writers in the nineteenth century, were found wanting as
effective translators from the Irish. But a new impulse to, and
pleasure in, the study of Gaelic poetry was contributed by the
vivid versions in kindred English forms of the great Irish prose
epics, and of the lyric passages with which they are studded,
as well as of the poems of the earlier and later bards wrought by
such writers as Edward Walsh and Sir Samuel Ferguson, Mangan
and Callanan, Whitley Stokes and Standish Hayes O'Grady, and
the editors of the Ossianic society's publications.
A band of contemporary authors, some of whom had already
translated many poems, have further answered to the call. This
became more easy, owing to the impetus given to the study of Irish
by the foundation of the Gaelic league. The Irish Text society was
started, and more than a dozen volumes of important English
translations from Irish classics have been issued by it. Many
translations have been the work of Irishwomen, while further
translations of Irish lyric poetry, Irish heroic tales and myths and
Irish dramatic poetry have been made. It is only during the last

twenty-five years that the language of this poetry has been
carefully studied, and later scholars have had the advantage
over their predecessors in being able to introduce with great
effect reminiscences of the characteristic epithets and imagery
which formed a large part of the stock-in-trade of the medieval
bard.
We have indicated that the interesting individual character of
early Irish literature makes it worth while getting that literature
more fully represented in the English language through translation,
adaptation and the use of Irish themes in original English writings.
