of great strength, nearly round, and is inclosed in the other, 

 which forms what is termed a sheath for it ; half-way down the 

 cannon, the perforans is 

 joined by a strong liga- 

 ment (the metacarpal) ; the 

 two tendons pass down 

 together through a sheath 

 formed for thein at the 

 back of the fetlock ; the 

 latter splits into two divis- 

 ions, having the perforans 

 passing between them ; 

 they are inserted one into 

 each side of the lower pas- 

 tern bone (or coronse), the 

 perforans, passing down, 

 is inserted into the sole of 

 the coffin-bone, just in 

 front of the navicular 

 joint, over which it passes. 

 A good illustration of these 

 different parts is given in 

 Fig. 821.
