ON THE STRUCTURE OF THE CHIMPANZEE. 

 BY H. C. CHAPMAN, M.D. 



The literature on the anatomy of the Chimpanzee is much more 

 extensive than that on the Gorilla, the animal having been dis- 

 sected by Tyson, 1 Traill, 2 Vrolik, 3 Schroeder Van der Kolk, 4

 Cliampneys, 16 and others. It may appear, therefore, superfluous 

 to offer the results of my dissection of the female Chimpanzee, 

 Troglodytes niger, which recently died at the Zoological Garden 

 of this city. In comparing, however, the accounts of the authors 

 just referred to, it becomes evident that the animals dissected by 

 them must in some instances have been different species of Chim- 

 panzees, and in others that they exhibited individual peculiarities. 

 The above accounts are, moreover, often limited to only portions 

 of the body. Indeed, the only elaborate modern treatises I have 

 seen are those of Vrolik and Gratiolet. The admirable mono- 

 graph of Tyson, old as it is, may still be consulted with the greatest 

 advantage. I propose confining myself to a general account of the 

 Chimpanzee I dissected, calling attention more particularly to the 

 points in which it differed from those previously described, and 

 the general resemblances and differences between it and the Gorilla 

 and Man. The specimen dissected by me was a female, supposed
