secondly, a comparison of the skulls of the adult male an^d 
female of one species -with those of the corresponding sex of the 
two others ; and, finally, of the skulls of young individuals. He 
has not been able to convince himself of the existence of more 
than three species. Of the contents of the concluding chapter 
(which is directed against Darwin) we have to mention,^Vs/, that, 
in the author^s opinion, there can be no question as regards the 
relative affinities between Man, Anthropoid Apes, and the oth^r 
Quadrumana, as soon as due attention is paid to the whole of 
the differences existing between them ; it is only when isolated 
points are taken into a one-sided consideration, that Man can be 
associated with the Anthropoids, and these separated from the 
other Quadrumana. Secondly, if we limit ourselves to the ex- 
amination of the skull and brain only (which are the most im- 
portant points), the Chimpanzee proves to approach more closely 
to Man than the Gorilla and Orang. Thirdly, if we assume Man 
to have descended in a direct line from a being of lower orga- 
nization, this being cannot be coexistent with Man ; and there- 
fore none of the Anthropoid Apes is his direct ancestor.

Troglodytes niger. Prof. Bischopp has examined two other skulls of the 
Chimpanzee, which confirm him in his opinion that Troglodytes tschego is not 
a distinct species. He refers also to Prof. BriihTs work on the Orangs (Wien, 
1856), in which the author distinguishes (erroneously) two species from the 
presence or absence of a crest on the head. Sitzgsber. bayer. Ak. 1867, i.
