THE GENERAL ANATOMY OF GORILLA

 though the Gibbons extend into the northern sub-tropical region. 

 In the following paragraphs, the Gorilla will be described as 

 the representative of the family, but so divergent in many ways 

 are the members of the latter, that references to each in turn will 

 be needed. No single member can be regarded as typical of 

 the whole series, and much stress is laid on this point. In such 

 a work as this, the exigences of space preclude detailed descrip-

 elsewhere. It remains to give reasons for the choice of Gorilla. 

 Hylobates (Fig. 96) is set aside because it is still reminiscent (so 

 to speak) of the Cercopithecidae, though in some respects highly 

 developed. The Orang-utan (Figs. 97, 98) is the visible expression 

 of Nature's scorn for those morphologists who ignore physiological 

 considerations. In more definite terms, it presents a complex 

 assortment of adaptive, progressive and even degenerate characters.
