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 inje6led 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;
