fluid or joint-oil, are situated, to lubricate the tendons 
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 
if they might contain air. They are usually found on 
horses that have been subjected to severe exertions, 
especially to fast work. Wind-puffs seldom interfere 
seriously with a horse’s ordinary work, but they are a 
serious blemish, and as an animal grows older they are 
likely to become more marked. In rare cases, the joint- 
oil which they contain may solidify into hard masses. 
The treatment for wind-puffs is the same as for 
bog-spavins,—— iodine, either as a tincture or ointment, 
hand-rubbing and pressure. Some cases can be sue- 
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. 
THOROUGH - PIN 
A thorough-pin is a puffy enlargement occurring 
half-way between the point of the hock and the front of 
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
