All the deciduous teeth were shed, and all the permanent teeth 

 (on the right or healthy side of the mouth) were in place, except the 

 canines and last molars ; these latter teeth were more advanced in 

 their development than the canines. This stage of dentition corre- 

 sponds with that of the human subject at about the twelfth year ; 

 but allowance must be made for the later period of development of 

 the canines in the Chimpanzee. Both upper and lower jaws on the 

 left side were enlarged by disease ; the gums inflamed and sloughy ; 

 the bicuspides or premolars and the first and second true molars had 

 been pushed out, and their fangs more or less absorbed. The left 

 outer permanent incisor of the upper jaw was half an inch distant 

 from the inner or median incisor, owing to intervening swelling of 

 the jaw. A section of the diseased left ramus of the lower jaw 

 showed the matrices of the canine and last molar in a healthy state 

 in the closed alveolar cavities. 



The irritation had extended to the left submaxillary and sublin- 

 gual glands, which were much enlarged. Both tonsils were ulcerated. 

 Both pleurae, but particularly the left, were partly closed by old ad- 

 hesions, which had obliterated the divisions of the lobes of the lungs. 

 Only one small portion of the pulmonary tissue was consolidated by 

 inflammation ; it was about the size of a walnut, and situated in the 

 lower lobe of the right lung, close to an adhesion of the pleura, but 

 there were no tubercles developed in any part of the lungs. 



A few old adhesions bound the spleen and omentum to the walls 

 of the abdomen ; all the other viscera of the abdominal cavity were 

 healthy. The most remarkable morbid appearance was found upon 

 the upper surface of the posterior lobe of the right hemisphere of the 

 brain, where a circumscribed depression of two convolutions was 

 formed, to which the dura mater strongly adhered, by the medium of 

 a yellowish firm lymph ; but there was no superficial ulceration of 

 the cerebral substance. 



With regard to the normal anatomy, 1 may at present add to the 

 full descriptions that have been published of the dissections of
