that spirit be fated, as
I believe it is, to extend itself into all departments of human thought,
and to become co-extensive with the range of knowledge; if, as our race
approaches its maturity, it discovers, as I believe it will, that there
is but one kind of knowledge and but one method of acquiring it; then
we, who are still children, may justly feel it our highest duty to
recognise the advisableness of improving natural knowledge, and so to
aid ourselves and our successors in their course towards the noble goal
which lies before mankind.

ON THE STUDY OF ZOOLOGY.*

([Footnote] *A Lecture delivered at the South Kensington Museum in
1861.)

Natural History is the name familiarly applied to the study of the
properties of such natural bodies as minerals, plants, and animals; the
sciences which embody the knowledge man has acquired upon these subjects
are commonly termed Natural Sciences, in contradistinction to other
so-called "physical" sciences; and those who devote themselves
especially to the pursuit of such sciences have been and are commonly
termed "Naturalists."

Linnaeus was a naturalist in this wide sense, and his 'Systema Naturae'
was a work upon natural history, in the broadest acceptation of the
term; in it, that great methodising spirit embodied all that was known
in his time of the distinctive characters of minerals, animals,
and plants. But the enormous stimulus which Linnaeus gave to the
investigation of nature soon rendered it impossible that any one man
should write another 'Systema Naturae,' and extremely difficult for any
one to become even a naturalist such as Linnaeus was.

Great as have been the advances made by all the three branches of
science, of old included under the title of natural history, there can
be no doubt that zoology and botany have grown in an enormously greater
ratio than mineralogy; and hence, as I suppose, the name of "natural
history" has gradually become more and more definitely attached to these
prominent divisions of the subject, and by "naturalist" people have
meant more and more distinctly to imply a student of the structure and
function of living beings.

However this may be, it is certain that the advance of knowledge
has gradually widened the distance between mineralogy and its old
associates, while it has drawn zoology and botany closer together; so
that of late years it has been found conv
