mere aesthetic intuition of the
uninstructed beholder.
And after passion and prejudice have died away, the same result will
attend the teachings of the naturalist respecting that great Alps
and Andes of the living world--Man. Our reverence for the nobility of
manhood will not be lessened by the knowledge that Man is, in substance
and in structure, one with the brutes; for, he alone possesses the
marvellous endowment of intelligible and rational speech, whereby,
in the secular period of his existence, he has slowly accumulated and
organized the experience which is almost wholly lost with the cessation
of every individual life in other animals; so that now he stands raised
upon it as on a mountain top, far above the level of his humble fellows,
and transfigured from his grosser nature by reflecting, here and there,
a ray from the infinite source of truth.
'A succinct History of the Controversy respecting the Cerebral Structure
of Man and the Apes.'
UP to the year 1857 all anatomists of authority, who had occupied
themselves with the cerebral structure of the Apes--Cuvier, Tiedemann,
Sandifort, Vrolik, Isidore G. St. Hilaire, Schroeder van der Kolk,
Gratiolet--were agreed that the brain of the Apes possesses a POSTERIOR
LOBE.
Tiedemann, in 1825, figured and acknowledged in the text of his 'Icones'
the existence of the POSTERIOR CORNU of the lateral ventricle in
the Apes, not only under the title of 'Scrobiculus parvus loco cornu
posterioris'--a fact which has been paraded--but as 'cornu posterius'
('Icones', p. 54), a circumstance which has been, as sedulously, kept in
the background.
Cuvier ('Lecons', T. iii. p. 103) says, "the anterior or lateral
ventricles possess a digital cavity [posterior cornu] only in Man and
the Apes...its presence depends on that of the posterior lobes."
Schroeder van der Kolk and Vrolik, and Gratiolet, had also figured and
described the posterior cornu in various Apes. As to the HIPPOCAMPUS
MINOR Tiedemann had erroneously asserted its absence in the Apes; but
Schroeder van der Kolk and Vrolik had pointed out the existence of what
they considered a rudimentary one in the Chimpanzee, and Gratiolet had
expressly affirmed its existence in these animals. Such was the state of
our information on these subjects in the year 1856.
In the year 1857, however, Professor Owen, either in ignorance of these
well-known facts or else unjustifiably suppressing them, submitted to
the Linnaean Soci
