44 HORSE AND MAN. 



upper part of the short pastern bone, and the other 

 to the floor of the coffin bone, after passing over the 

 navicular bone. This tendon, therefore, twice changes 

 its line, each time gaining an increase of power. 



In the front of the limb runs the extensor tendon. 

 It also divides into two portions, one being attached 

 to the short pastern bone and the other to the coffin 

 bone. These two tendons, therefore, or rather the 

 muscles to which they are attached, would continually 

 pull against each other were it not for the provision 

 that the one is always relaxed in proportion as the 

 other contracts. At H is shown the suspensory liga- 

 ment, the name of which indicates its use. 



These tendons and their attachment can readily 

 be observed in a dried specimen, although it is more 

 satisfactory to study them from the recent subject. I 

 have now before me a section of a pastern which was 

 made many years ago, and has been subjected to very 

 hard usage. It is, however, in perfect preservation, 

 and, unless wilfully damaged, will remain unchanged 

 for centuries. 



I recommend the reader to colour all these ana- 

 tomical illustrations, every one of which has been 

 drawn from the actual object. 



At s, on page 40, is shown the coronary ring, which 

 secretes the horn of the wall. Being extremely vascular 

 - i.e. filled with arteries and veins, it shrivels almost to
