 the animal is turned over. See to it that the hocks are completely 

 flexed and that the feet are not extended too far forward. After 

 the hind legs are secured apply knee strap (M) to off fore leg. 

 The Miles' spreaders (Fig. 39) are now applied, after which the

 ling" horse on the operating table, nevertheless its practicability 

 is seriouslv doubted.
