ing more to the right, a very small supplementary spleen existed. The 

 liver, though covered writh tuberculous maculce, when cut into exhibited 

 in its interior no tubercles. The mesenteric glands were also filled with 

 the same cheesy substance mentioned above, and one large mass was in 

 a state of partial suppuration. 



The cavity of the thorax, generally speaking, was in an equally dis- 

 eased state with that of the abdomen. A purulent serous eflPusion had 

 taken place, with adhesion of the lungs, more especially the left lobe, to 

 the thoracic parietes. On cutting into the left lobe, it was found con- 

 verted into a mass of cheesy tubercles, but no suppuration l.ad taken 

 place ; the appearance of the right lobe was similar, but the disorgani- 

 zation was less in degree. The heart was sound. 



On the whole, from the appearances manifested on examination, it 

 was obvious that the Orang Outang had died from the effects of general 

 inflammation of the thoracic and abdominal viscera, but wheiher this had 

 commenced with the abdominal or thoracic is not easy to determine. The 

 brain was not examined. 



On examination of the sexual orgars of the Orang Outang, some dif- 

 ficulty arose in duly ascertaining them, on account of the minuteness of 

 some of the parts. On introducing a director into the external meatus 

 beneath the root of the clitoris (which, as already stated, was only large 

 enough to admit the end of a crow-quill) an incision was carefully made 

 down the perincEum. On thus laying open the external meatus, two ori- 

 fices or canals were discovered, the upper one of which quite under the 

 root of the clitoris was found to be the urethra, and was large enough 

 to admit a small bougie or probe into the bladder. The lower aperture 

 or orifice of the vagina was large enough to admit a common-sized pen- 

 cil. The canal was about an inch and a half long, evidently dilatable, 

 and of the diameter (undilated) of a common pencil-case. A blunt 

 probe introduced into it was felt with the finger in the pelvis, where it 

 met resistance from the os tinceB of a small uterus, which it required 

 minute search to find ; but the existence of which, with its fallopian 

 tubes and ovaries was satisfactorily demonstrated ; thus the question of 

 the creature's sex was set at rest. 



The pectoral air-sacs or membranous bags peculiar to the Orang spe- 

 cies, and communicating with the larynx, were found very distinct, but
