112 MAN AND APES. 



nine of such ossicles, an extra bone, called the 

 intermedium, being interposed between the 

 Scaphoides, the Trapezoides, and the Magnum. 

 In the Gorilla and Chimpanzee there are but 

 eight, while the Orang and Gibbons have, like 

 the other monkeys, nine. It is very remark- 

 able that amongst the Lemuroidea we find 

 certain forms, namely, Indris and Lepilemur, 

 which agree with Homo and Troglodytes in 

 having but eight bones to the wrist. One of 

 these wrist-bones (the Pisiform) is much 

 smaller relatively in man and in the Orang 

 than in almost any other species of the order. 

 Strange to say, however, we find in the little

 this respect to man much beyond that ex-

The thumb, as to its relative length, taking 

 again the back-bone as our standard of com- 

 parison, is in the Gorilla more like that of 

 man than is the thumb of any other of the
