 as they play over each other. Wind- puffs are usually 

 located on either side of the leg, more particularly on 

 ♦the outer side just above the fetlock- joint, between 

 the back tendons and the bone. They are noticed as 

 rounded or elongated puffy enlargements that feel as

 likely to become more marked. In rare cases, the joint- 

 oil which they contain may solidify into hard masses. 

 The treatment for wdnd- puffs is the same as for 

 bog- spavins, — iodine, either as a tincture or ointment, 

 hand -rubbing and pressure. Some cases can be suc- 

 cessfully treated by drawing off the synovial or joint- 

 oil, by means of a hypodermic syringe, and injecting 

 a solution of iodine. This should be attempted only 

 under the direction of a well -qualified person.

 the hock- joint. It is the same condition as a wind- puff, 

 — a soft puffy enlargement occurring both on the inside 

 and the outside of the leg, in the hollow just in front of 

 the large tendons which are inserted in the point of 

 the hock. By gentle pressure, the synovial fluid can 

 be pressed through from one side to the other; hence
