 the Gibbons. 



In the breadth of the pelvis, compared with 

 its extent from before backwards, man is more 

 nearly reached by some Baboons than by any 

 latisternal ape. 



The haunch-bone (os innominatum) is made

 and 3, the ischium — which have coalesced 

 into one mass (Fig. 51, a). 



In the length of the whole mass, compared 

 with that of the spine, the Gorilla, Chim-

 this tuberosity is a prominence called the

The shortness of the ischia, the smallness 

 and the non-eversion of the tuberosities, and
