MAN AND APES. 121 



the prolongation of the latter upwards nearly 

 to the spines of the ischia, are four characters 

 almost peculiar to man. He is most nearly 

 approached in these points, not by the 

 Gorilla, nor by any of the Simiince, but by 

 the Slender Lemur (Loris). 



The development of the spine of the 

 ischium is much more human in the Orang 

 than either in the Chimpanzee or Gorilla. 



The length of the thigh-bone (femur) 

 compared with that of the back-bone, is 

 greater in man than in any latisternal ape. 

 He is most nearly approached in this respect 

 by the Spider Monkeys (Ateles), while in the 

 Gibbons it is even longer than in man. 



Comparing the length of the thigh-bone 

 with that of the haunch-bone, we find the 

 short-tailed Indris to be the most human, 

 while Hylobates is more so than are the higher 

 genera of Simiince. 



In man the relative length of the thigh- 

 bone to the humerus is enormously greater 

 than in any latisternal ape. The Lemurs
