Skeleton of the Oorilla. 41 



gorilla, and all the quadrumana. Moreover, there is probably 

 another great difference in this region between man and 

 gorilla. I am informed by my friend and colleague, 

 Professor M'Coy, that in the chimpanzee, by many supposed 

 nearer to man than the gorilla is, a bone exists in the _pe7iis. 

 I found one also in the penis of the macaque, and it is most 

 likely one will be found in the gorilla, as the drawing of this 

 organ in Professor Duvernoy's plates resembles that of the 

 macaque. Nothing of the kind has ever been discovered in 

 any variety of the human species. Now it is an universal 

 law that no part of the body withers and dies out, unless 

 from disj^/se. Use and nutrition being the same, a part 

 remains the same, and when we come to the question of 

 descent, this is the very pai't of an animal that must have 

 been used to have raised our question. What reason have 

 we to believe that our old quadrumanous ancestor was less 

 active in this matter than are the apes and monkeys of the 

 present day ? Those who, striving to uphold the doctrine 

 of the transmutation of species, say that if not of the apes 

 we may be from, should tell us how this bone has 

 disappeared from man. This may be the place to say 

 that the young gorilla, like the young of brutes in 

 general, becomes sooner independent of its parents than the 

 young of the human species. Little Joe, as Du Chailiu 

 calls him, was not three years old ; his height was two feet 

 six inches. This is rather short for a child of the same age. 

 Yet Du Chailiu was compelled, in order to bring him in, to 

 take ' hold of the back of his neck, two men seizing his 

 arms and another his legs ; and thus held by four men, this 

 extraordinary little creature still proved troublesome.' The 

 Scapula, blade bone, has some points of resemblance to 

 the human. It differs in the spine springing further from 

 its posterior border, and making thQ supra and infra-spinou^ 

 fossce of more equal dimensions. It does not present, as in 

 man, a generall}" concave surface for origin of the suhscapa- 

 laris, but a median convexity towards the thorax. In this 

 and in the following particulars, it approaches more the 

 scapula of macaque, viz., a well-marked elongated excavation 

 for the long head of the triceps muscle and part of suhscct- 

 palaris and a proportionally larger coracoicl process. The 

 Humerus, both in man and macaque, is shorter than the 

 femur, but in the gorilla it is much longer than the femui\ 

 Excepting its size, and the more prominent outer convexity 

 of its inferior trochlear sujrface and the boundaries of the
