made him put the pup down. He then climbed up to the top of the 

 cage where the Marmozets were, and jumped furiously upon it, evi- 

 dently to astonish the inmates, who were astonished accordingly, and 

 huddled together, looking up in consternation at this dreadful pother 

 o'er their heads. Then he went to the window, opened it and looked 

 out. I was afraid that he might make his escape : but the word* 

 " Tommy, no ! " pronounced by his keeper in a mild but firm tone, 

 caused him to shut the window and come away. He is in truth a 

 most docile and affectionate animal, and it is impossible not to be 

 taken by the expressive gestures and looks with which he courts 

 your good opinion, and throws himself upon you for protection 

 against annoyance. 



" It must be remembered that though I have not obsei-ved our Chim- 

 panzee to progress with his bent knuckles touchingthe ground, as I have 

 seen the Asiatic Orangs move, there is no reason for doubting the ac- 

 curate descriptions of Tyson and Dr. Traill. I consider it as my pro- 

 vince to relate faithfully what I saw, and I have only seen our Chimpan- 

 zee, as yet, in a small room, where a very few paces will bring him to a 

 chair, a leg of a dresser, or some other piece of fumitiu-e which en- 

 ables him to call into action his prehensile hands and feet, so admi- 

 rably adapted to his arboreal habits. The narrowness of the pelvis, 

 the comparatively inferior development of the glutai * and gastro- 

 cnemii muscles, and other peculiarities of conformation so ably pointed 

 out by Tyson, Dr. Traill, and others, but more particularly by Mr. 

 Owen, show that the erect, or, more properly speaking, the semi- 

 erect position, is not the natural one ; though my observations upon 

 living Asiatic Orangs and Chimpanzees accord with the inference 

 drawn by Mr. Owen from the comparative organization of the lat- 

 ter, viz. that the semi-erect position is more easily maintained by the 

 Chimpanzee than by any of the other known Simite. 



" The great intelligence and strength of the individual now in the 

 menagerie of the Society, added to the state of its dentition, raised 

 a doubt in my mind as to the accuracy of the report of its age; and I 

 wrote to my friend Mr. Owen my suspicion that he might be older 

 than he was said to be. I received the following reply, in which so 

 much valuable information is concentrated that I feel it to be due to 

 those who may think this memoir worthy of attention to give it as 

 I received it.

" ' My dear Broderip, — I feel that we have no data towards deter- 



• This must be understood as limited to a comparison with the same 

 muscles in man ; for there is in the Chimpanzee as Mr. Owen observes, " a 

 provision for a more extended attachment for the glutcei muscles, in a greater 

 breadth of the ilia between the superior spinous processes, than is. observed 

 in the inferior Simice."
