ON FOSSIL REMAINS OF MAN S511 
last great physical changes of Europe, and its owner was a con- 
temporary of the mammoth, the tichorine rhinoceros, the cave bear, 
and the cave hyena, so that a vast gulf of time separates him from 
the Borreby men. The skull was shown, however, by all its 
measurements, to be nearly as well developed as that of an average 
European. 
The Neanderthal skull, whose age is not exactly known, on the 
contrary, is the lowest and most ape-like in its characters of any 
human skull yet discovered, though it presents certain points of 
resemblance to the Borreby skulls. 
Great as are the differences between the Engis, the Borreby, and 
the Neanderthal skulls, the speaker stated that it would not be justi- 
fiable to assign them even to distinct races of men; for by a careful 
examination of the crania of one of the purest of living races of men 
—the Australian,—it is possible to discover skulls which differ from 
one another in similar characters, though not quite to the same 
extent, as the ancient ones. 
Thus it appears that the oldest known races of men differed com- 
paratively but little in cranial conformation from those savage races 
now living, whom they seem to have resembled most in habits ; and 
it may be concluded that these most ancient races at present known 
were at least as remote from the original stock of the human species 
as they are from us.
