PAPIO MAIMON. 19 



bending clown, its direction becomes the same as the surface of the 

 scrotum. 



There are two small muscles which arise from the crura penis, which 

 run along the body of the penis, and are inserted into two small tendons 

 which continue the same course along the back of the penis, and are at 

 last lost or fixed into the penis near the glans. 



The clavicles, instead of being placed horizontally, rise obliquely 

 upwards towards the shoidders, which gives the animal the appearance 

 of having a short neck. Their connexion with the sternum is looser 

 than in the human subject. 



The two swelhngs on the lateral and upper parts of the head, covered 

 with white hairs, are the temporal muscles, which must be very strong 

 for their size 1 . 



[The Black Baboon [Cynocephalus sphingiola, Herm) 2 .] 



In a large baboon monkey the contents of the thorax were much as 

 in the dog. The vesiculse seminales were seen in the pelvis without 

 dissection. There are two small muscles [compressores vena3 dorsalis 

 penis] on the fore-part of the penis near the root, as in the squirrel. 

 There was a small bone in the penis near the glans. The tunica 

 vaginalis communicates with the cavity of the peritoneum as hi most 

 brutes. The cremaster is lost on that part of the tunica vaginalis that 

 adheres to the lower end of the testes. 



The testes, and the ramifications of their vessels, are as in brutes. 

 There is an attachment of epiploon to each testis by a very small elon- 

 gation of it : this attachment is to the same part of each testis, and the 

 very same sort of attachment in each.

The lungs are divided into four lobes on the right side, two large, viz. 

 the upper and lower, and one smaller or middle and anterior, and the 

 lobe behind the vena cava which is a very small one, not passing down 

 between the heart and diaphragm : there are two lobes on the left [side 

 of the chest]. The pulmonary cells are larger than those of the human 

 or most other animals. 



The trachea is not closed behind, but [the ends of the rings are]
