what ancestry man may have been derived from such primordial form 
he knows not. Suffice it to say that it is neither to Gorilla, to Koo- 
loo Kamba, to Orang, to Dryopithecus, nor to any known recent or 
fossil ape he can claim his descent. 
But the mind of the palaeontologist, still aiming at a solution, re- 
calls the hideous ape-like character of the Neanderthal man, and 
strives to divest himself of the idea that this frightful being belonged 
to the same race as himself. Demonstration is lacking of the mode 
by which even so low and degraded a type could have been derived 
from the apes. Whether demonstration will ever afford us such a 
solution is the object towards which Anthropologists, Zoologists, and 
Geologists are directing their best endeavours,— with what success 
remains to be seen.

When we view the skeleton of man, when we trace the points of 
difference between his form and that of the anthropoid apes, we are 
struck with the " all-pervading" unity of plan and " similitude of 
structure, — every tooth, every bone strictly homologous," — which is 
presented by these organs throughout their diversified adaptations. 
We can trace out in both the human jaw and that of the ape the same 
canine tooth : e. g. as the modified representative and homologue of 
the canine in Hycenodon, now subserving its duty in the gorilla as an 
almost carnassial laniary, now dwarfed in mail into the semblance 
merely of a more conical incisor. In each bone of the metacarpals
