The walls of the sack should then be brought into close 

 contact by a firm flannel bandage, and the horse be rested 

 for a Aveek.

Bub well together, and apply by gentle friction every day, until the

CAPPED HOCK. 



Definition. — A swelling on and around the j)oint of the 

 hock, caused either by an effusion into the tendon of the gas- 

 trocnemius muscle — Synovial Capped Hock — or into the 

 loose tissue between that tendon and the skin — ^Serous Capped 

 Hock. 



Causes. — Both these forms of capped hock generally pro- 

 ceed from kicking and striking the point of the hock against 

 some hard object, and are indicative of a vicious temper as 

 well as of an unsound horse. The synovial form causes 

 lameness, but the serous form does not necessarily do so. 



Treatment. — The serous form can generally be cured by 

 blistering and applying firm presssure with a strong elastic 

 bandage. The synovial form must be managed in the same 

 manner laid down for thorough-pin, it being a disorder of a 

 etrictly similar nature. 



SIDE BONES. 



Definition. — A change to a bony substance, taking place in 

 the lateral cartilages of the fore feet. 



Causes. — This change is usually found in heavy draught 

 horses, and is attributed to the over expansion of the car- 

 tilages from the great weight of the animal, added to a he- 

 reditary tendency, and shoeing with high calks.
