THE DESCENT OF MAN. 
Part I 
Dr. Lund , 6 that the human skulls found in the caves of 
Brazil, entombed with many extinct mammals, belonged 
to the same type as that now prevailing throughout the 
American Continent. 
Our naturalist would then perhaps turn to geogra- 
phical distribution, and he would probably declare that 
forms differing not only in appearance, but fitted for 
the hottest and dampest or driest countries, as well as 
for the arctic regions, must be distinct species. He 
might appeal to the fact that no one species in the 
group next to man, namely the Quadrumana, can resist 
a low temperature or any considerable change of climate ; 
and that those species which come nearest to man have 
never been reared to maturity, even under the temperate 
climate of Europe. He would be deeply impressed with 
the fact, first noticed by Agassiz , 7 that the different 
races of man are distributed over the world in the same 
zoological provinces, as those inhabited by undoubtedly 
distinct species and genera of mammals. This is mani- 
festly the case with the Australian, Mongolian, and 
Negro races of man ; in a less well-marked manner with 
the Hottentots; but plainly with the Papuans and 
Malays, who are separated, as Mr. Wallace has shewn, 
by nearly the same line which divides the great Malayan 
and Australian zoological provinces. The aborigines 
of America range throughout the Continent ; and this 
at first appears opposed to the above rule, for most of 
the productions of the Southern and Northern halves 
differ widely ; yet some few living forms, as the 
but Messrs. Nott and Gliddon (ibid. p. 146, fig. 53) describe bim as 
u a hybrid, but not of negro intermixture.”

They give also corroborative evidence ; but 0. Vogt thinks that the 
subject requires further investigation.
