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 Dryopitliecus, 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 Hycsnodon, now subserving its duty in the gorilla as an 

 almost carnassial laniary, now dwarfed in man into the semblance 

 merely of a more conical incisor. In each bone of the metacarpals
