STEATOPARESIS 



with regard to position, to the adipose cheek-expansions observed 

 in orang-utans, to which the term " Steatoparesis " (fatty cheeks), 

 might be conveniently applied. And the analogy might even be 

 extended to the fatty tail of certain races of sheep, to the hump of 

 the zebu, and perhaps to the facial warts of certain pigs. 1 



In the Mayas, moreover, the steatoparesis bears a definite rela- 

 tion to certain cranial characters. x\mongst the skulls of these 

 orangs there are some quite smooth along the vertex, like a human

skull, others, instead, present a well-marked median sagittal crest, 

 which corresponds to the insertions of the big temporal muscles ; 

 and in addition, at right angles to the latter, a great lambdoidal 

 crest rises across the skull from ear to ear. As a general rule, when 

 cheek-expansions are not present there are no cranial crests, and 

 this is the case also in fully adult and very aged specimens. Thus 



1 A beginning of steatoparesis, or fatty thickening of the cheeks between 

 these and the ears, is sometimes apparent in the human species in stout, 

 well-fed persons.
