mediately behind the lower half of the shank-bone be- 

 tween it and the back tendons, some enlaigement is 

 detected with heat and tenderness. In bad cases, with 

 descent of the fetlock, the whole length of the cord is 

 thickened and the infiltration of the surrounding parts 

 gives the whole back of the limb a soft doughy feeling. 

 TreatTTient is much less satisfactory than in sprains of the 

 back tendons but the principles are the same, though 

 a much longer period of rest and blistering is usually 

 demanded. In severe forms with descent of the fetlock, 

 that must be supported by splints and bandages, in the 

 same manner as after cutting the back tendons, otherwise 

 the limb will be permanently distorted. These severe 

 cases, which usually result from the most violent exertions 

 in racing or hunting, rarely recover so as to be fit for such 

 work in future, though they may be useful for service at a 

 slow pace.

This is the result of sprains or severe exertions and is al- 

 ways associated with round elastic synovial swellings on 

 each side of the tendons, familiarly known as puffs or wind- 

 gcdls. Similar swellings arise, independent of sprains, as 

 the result of over-exertion or dropsy of the part. The 

 swellings may become sohd by coagulation of the lymph 

 and may be absorbed or organized, or the inflammation 

 may attack the bone, leading to ulceration and bony de- 

 posits. Similar bony deposits with or without ulceration 

 may take place on these small bones in connection with 

 injuries of the suspensory ligament. 



Treatment. Simple wind-galb, dropsical or from over- 

 exertion, may be made to disappear by persistent pressure 

 with a bandage and pads applied at first two hours twice 

 a day, and two hours more every day thereafter, until 

 they can be kept on aU the time. It may, however, re- 

 quire five or six weeks and shoidd be stopped if H
