A hind hmb may be secured in a simple way by passing the end 

 of the tail round it m front of the hock (Fig. 284); any violent and 

 extensive movement of the limb is then necessarily painful to the 

 animal owing to the tension of the tail. 



Greater security, however, is given by passing a rope backward 

 and forward around the hind legs, above the hocks, in the form of

 the hind limbs, but it limits them and secures both animal and 

 operator from danger. 



Should it become necessary to examine the hind foot or inter- 

 digital space, it is useful at times to pass a loop of cord round the 

 leg in the region of the tendo Achillis, and 

 to twist and tighten this loop by a short, 

 stout stick passed through it ; this is the leg 

 twitch described in Dollar's " Operative Tech- 

 nique," p. 7. 



For such examinations, however, the 

 animal is usually placed in the trevis, or is 

 secured to the side of a long waggon (Fig. 286).

For castration in the standing position a hind and a fore limb 

 may be fastened together, as shown in Fig. 287.
