that we cannot prove that they have been produced by artificial or
natural selection, the objection must be admitted--ultra-sceptical as it
is. But in science, scepticism is a duty.

ON THE EDUCATIONAL VALUE OF THE
NATURAL HISTORY SCIENCES.
The subject to which I have to beg your attention during the ensuing
hour is "The Relation of Physiological Science to other branches of
knowledge."
Had circumstances permitted of the delivery, in their strict logical
order, of that series of discourses of which the present lecture is a
member, I should have preceded my friend and colleague Mr. Henfrey, who
addressed you on Monday last; but while, for the sake of that order, I

of Biology in general _does_ precede that of Special Zoology and Botany,
I am rejoiced to be able to take advantage of the light thus already
