made by his shoe, by a mental process identical with that by
which Cuvier restored the extinct animals of Montmartre from
fragments of their bones. Nor does that process of induction and
deduction by which a lady, finding a stain of a peculiar kind on
her dress, concludes that somebody has upset the inkstand
thereon, differ in any way, in kind, from that by which Adams and
Leverrier discovered a new planet."

In one of his addresses to working men on _Man's Place in Nature_ he
shewed that from time to time in the history of the world average
persons of the human race have accepted some kind of answer to the
insoluble riddles of existence, but that from time to time the race
has outgrown the current answers, ceasing to take comfort from them.

"In a well-worn metaphor a parallel is drawn between the life of
man and the metamorphosis of a caterpillar into a butterfly; but
the comparison may be more just as well as more novel, if for its
former term we take the mental progress of the race. History
shews that the human mind, fed by constant accessions of
knowledge, periodically grows too large for its theoretical
coverings, and bursts them asunder to appear in new habiliments,
as the feeding and growing grub, at intervals, casts its too
narrow skin and assumes another, itself but temporary. Truly, the
imago state of man seems to be terribly distant, but every moult
is a step gained, and of such there have been many."

As another instance, the following from his address on a "Liberal
Education" may be taken. He had been discussing the intellectual
advantage to be derived from classical studies, and had been
comparing, to the disadvantage of the latter, the intellectual
discipline which might be got from a study of fossils with the
discipline claimed by the ordinary experts upon education to be the
results of classical training. He wished to anticipate the obvious
objection to his argument: that the subject-matter of palaeontology had
no direct bearing on human interests and emotions, while the classical
authors were rich in the finest humanity.

"But it will be said that I forget the beauty and the human
interest, which appertain to classical studies. To this I reply
that it is only a very strong man who can appreciate the charms
of landscape as he is toiling up a steep hill, along a bad road.
