From the above admeasurements it appears that the Hottentots and Papuans of 

 Australia have the smallest cranial capacity amongst the Human races ; but that the 

 largest capacity yet observed in the adult male Gorilla is less than one-half the mean 

 capacity in those .^Ethiopian races. 



The Chimpanzee, Troglodytes niger, with its inferior size, has also a lower capacity of 

 cranium than the Gorilla has ; and the Orang has a smaller capacity of cranium 

 than in either of the two species of Chimpanzee.
