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
