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 Aithiopian 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.
