who has taken as much trouble as I did to assure himself that
they are truths, let him come out with them, without troubling
his head about the barking of the dogs of St. Ernulphus.
_Veritas praevalebit_--some day; and even if she does not
prevail in his time, he himself will be all the better and
wiser for having tried to help her. And let him recollect
that such great reward is full payment for all his labour and
pains.

To speak out thus was one side of his passion for veracity. When it
was a matter of demonstrable truth, he refused to be intimidated by
great names. Already, in his Croonian lecture of 1858, "On the
Theory of the Vertebrate Skull," he had challenged, and by direct
morphological investigation overthrown, the theory of Oken, adopted
and enlarged upon by Owen, that the adult skull is a modified
vertebral column. Again, the great name of Owen, that jealous king of
the anatomical world, had in 1857 supported the assertion, so contrary
to the investigations of Huxley himself and of other anatomists, that
certain anatomical features of the brain are peculiar to the genus
_Homo_, and are a ground for placing that genus separately from all
other mammals--in a division, Archencephala, apart from and superior
to the rest. Huxley thereupon re-investigated the whole question, and
soon satisfied himself that these structures were not peculiar to man,
but are common to all the higher and many of the lower apes. This led
him to study the whole question of the structural relations of man to
the next lower existing forms. Without embarking on controversy, he
embodied his conclusions in his teaching.

Thus, in 1860, he was well prepared to follow up Darwin's words in the
