termination can generally be easily felt by the fingers ; as 

 this bony ridge ends abruptly in the crest. 



The Elbow, which is a portion of the fore arm, is the 

 large bony projection at the upper and posterior part of the 

 fore arm. The point of the elbow (z) is the top of this 

 bony projection. 



The Fore Arm (5) is placed between the shoulder and 

 knee. Its upper boundary may be taken as a horizontal 

 line drawn across the fore limb, just below the lump of muscle 

 which is at the bottom of the shoulder. 



The castors, corns, or chesnuts [k) are the horny growths 

 which are, respectively, above the knees, and just below the

 of the knee may be taken as a line joining the point where

 fetlock is one drawn across the leg immediately above the

The back tendons {m) or back sinews are the fibrous cord 

 which runs down the back of the leg between the knee and

The suspensory ligament is a fibrous cord which lies
