5758. The right moiety of a vertically bisected cranium of an Esquimaux. 



The parietes of the cranium are thinner and its capacity greater than in the Australian, but 

 do not exceed those in the Negro. The entocondyloid prominence is less developed than in 

 the Negro and Australian. The upper jaw is rather less produced than in the Negro, but 

 the distance between the back part of the basioccipital and the fore part of the premaxillary 

 is as great, and there is much diploe in the basioccipital. 



Prepared in 1852. 



5759. The right moiety of a vertically bisected cranium of a European. 



It shows a greater vertical capacity, especially at the frontal region, than in the foregoing 

 cranial sections ; but is chiefly distinguished by the shorter and less produced upper jaw, and 

 by the minor extent of the facial part between the basioccipital and premaxillary. The basi- 

 occipital is of much less vertical extent, and contains less diploe ; and the entocondyloid pro- 

 minence is less developed. 



Hunterian.

In the three following skulls, a vertical section has been made through the middle of the 



left orbit. 



Prepared in 1852. 



5760. The cranium of an Australian. Presented by George Bennett, Esq., F.L.S. 



5761. The cranium of a male African Negro, of the subelongate type, moderately 

 protuberant at the parietal region, narrow and rather lower at the frontal 

 region ; with broad, flattened nasals, protuberant malars, and broad and pro- 

 duced upper jaw. 



The section shows the dense and thick parietes of the cranium, and, as compared with the 

 Australian skull, No. 5760, a greater depth of the cavity at its hinder third, greater thickness 

 of the parts supporting the cerebellum, and a more oblique position of the base of the alisphe- 

 noid. The right paroccipital is well developed. 



5762. The cranium of an Englishman. Prepared in 1852. 



On comparing together the preceding skulls of the Australian, the Negro, and the European, it will 

 be seen that the fore part or entry of the orbit in the two Black races is more contracted, chiefly by the 

 production downwards of its roof at that part. In the European it is more open, as if from a more 

 habitual and freer upward gaze. The cranial parietes are thicker and denser in the Black races. The 

 divided part of the alisphenoid is thicker, and the space between that and the orbitosphenoid is less. 

 The basal fossa for the natiform protuberance is larger in the European than in the African Negro, and 

 deeper in the Negro than in the Australian. The characteristic magnitude of the molars is well displayed 

 in the Australian skull.
