remember," on materia medica at eight o'clock on a winter's morning,
and, worse still, Dr. Munro's lectures on human anatomy, which were "as
dull as he was himself." Yet he always deeply regretted not having been
urged to practise dissection, because of the invaluable aid it would
have been to him as a naturalist.

By mental instinct, however, Darwin soon found himself studying marine
zoology and other branches of natural science. This was in a large
measure due to his intimacy with Dr. Grant, who, in a later article on
Flustra, made some allusion to a paper read by Darwin before the Linnean
Society on a small discovery which he had made by the aid of a "wretched
microscope" to the effect that the so-called ova of Flustra were really
larvæ and had the power of independent action by means of cilia.

During his second year in Edinburgh he attended Jameson's lectures on
geology and zoology, but found them so "incredibly dull" that he
determined never to study the science.

Then came the final move which, all unknowingly, was to lead Darwin into
the pursuit of a science which up to that time had only been a hobby and
not in any sense the serious profession of his life. But again how wide
the difference between his change from Edinburgh to Cambridge, and that
of Wallace from a month's association with a working-class Socialistic
community in London to land surveying under the simplest rural
conditions prevalent amongst the respectable labouring farmers of
Bedfordshire--Darwin to the culture and privileges of a great University
with the object of becoming a clergyman, and Wallace taking the first
road that offered towards earning a living, with no thought as to the
ultimate outcome of this life in the open and the systematic observation
of soils and land formation.
