SLOW LEMUR. 91 



pleasure as he could have enjoyed in a state of 

 captivity." 



From the above description we perceive that 

 this animal, slow and inert as it is, is yet not quite 

 so torpid and inactive in India, as when brought 

 into the colder climates of Europe. 



The following observations, communicated by 

 the excellent anatomist Mr. Carlisle, cannot but 

 be acceptable to the reader. They are accom* 

 panied by an engraving from his elegant drawings. 



" The body of a Lemur tardigradus having 

 been presented to me by a friend, for the purpose 

 of dissection, I injected the arterial system, and 

 upon tracing the course of the vessels, so as to 

 make a dried preparation, an unusual appearance 

 of distribution was exhibited by the large trunks 

 of the subclavian and external iliac arteries. 



" Immediately after the subclavian has pe- 

 netrated the axilla, it is divided into twenty- 

 three equal-sized cylinders, which surround the 

 principal trunk of the artery, now diminished in 

 size to an inconsiderable vessel. These cylindri- 

 cal arteries accompany each other and divide with 

 the ulnar and radial branches, being distributed 

 in their route upon the muscles, each of which 

 has one of these cylinders. The other branches, for 

 example, the radial and ulnar, proceed like the 

 arteries in general; dispersing themselves upon 

 the skin, the membranes, joints, bones, &c. in 

 an arborescent form. The iliac artery divides 

 upon the margin of the pelvis into upwards of 

 twenty equal-sized cylinders, surrounding the 

 main trunk, as described in the axillary artery :
