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 a 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 pleure, 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, | may at present add to the 
full descriptions that have been published of the dissections of
