THE R A I N-D E E R« 361 



The prepuce is naked, like a navel, full of 

 wrinkles in the infide, and covered with a cal- 

 careous cruft. 



The hoofs are large, long, and convex on the 

 outfide. The fpurs are alfo very long, and fome 

 of them touch the ground when the animal 

 ftands. They were hollow, probably becaUfe he 

 makes no ufe of them. 



The inteftines were exactly fimilar to thofe 

 of the fallow-deer. There was no gall-bladder. 

 The kidneys were fmooth, and undivided. The 

 lungs and wind-pipe were very large. 



The heart was of a middle fize, and, like that 

 of the fallow-deer, contained one fmall bonk 

 only. This bone fupported the bafe of the fe- 

 milunar valve of the aorta, which is oppofed to 

 two others, from which the coronary arteries 

 of the heart derive their origin. It likewife 

 gives firmnefs to the membranous partition be- 

 tween the two cavities of the heart, and to the 

 triglochine valve of the right ventricle. 



In this animal there is a fingalar pouch, very 

 large, membranous, and fituated under the ikin 

 of the neck. In begins by a conical canal be- 

 tween the os hyoides and the thyroide cartilage. 

 This canal gradually enlarges, and is changed 

 into a kind of membranous fac, fupported by 

 two oblong mufcles, which derive their origin 

 from the inferior part of the os hyoides, precife- 

 ly where the bafe, the piiiform bene, and the 

 rnua unite.
