 The Vascular System.

The following are some points about the vessels which appeared 

 to me interesting. The aortic arch only gives off two branches, 

 the innominate and the left subclavian ; the former after giving 

 off' the right subclavian divides into right and left carotids *.

1. Parotid gland. 2. Submaxillary gland. 3. External Jugular Tein. 

 4. Deep Parotido-auricularis muscle. 5. Placed just above the transverse 

 facial artery (the other black lines represent the branches of the Facial Nerve). 

 6. Parotid (Stensen's) duct. 



The face is supplied, as in many other long-faced mammals, not 

 by a facial artery coming over the mandible as in Man, but by a 

 branch which comes of£ from the root of the temporal artery at 

 the termination of the external carotid, and which is represented, 

 I suppose, by the transverse facial artery of Man. 



The brachial artery passes through the supracondylar foramen 

 with the median nerve, and then continues down the forearm 

 with that nerve as a median artery until the palm is reached. 

 The aorta terminates in the usual marsupial method, the two 

 external iliacs coming of£ some distance above the two internal. 

 The femoral artery gives off a large saphenous branch in the 

 lower part of the thigh ; this reaches the posterior surface of the 

 tibia and eventually the sole of the foot. 



There are two prevense cavse ; the post vena cava lies ventral 

 to the termination of the abdominal aorta, as is so often the 

 case among marsupials.
