DISEASES OF THE LEGS AND FEET. 115 



windgalls for the time being, but they appear again shortly 

 after the bandages are removed. A prolonged rest and a blister 

 also serve to remove windgalls for a time. 



Thoroug:h-pins. — These have their seat in the hollow 

 at the side of the hock, and are similar in nature to windgalls. 

 The causes of thorough-pins are strain and the effects of work 

 and wear. As a rule, they cause no inconvenience, and are 

 merely eyesores. Rest and blistering serve to remove them to 

 a greater or less extent for a time. 



Bog'-spavin. — This complaint must not be confused with 

 bone-spavin. Its seat is at the front of the hock, and it con- 

 sists in a soft swelling of varying size. It is identical with 

 windgalls and thorough-pins as regards its nature. Usually 

 bog-spavins are of no importance, and, like thorough-pins, 

 they are merely eyesores. Treatment is unavailing, though 

 rest and blisteiing may effect a decrease in the size of the 

 enlargement for a time. 



Capped Elbow. — Unless of very large dimensions, the 

 swelling known as " capped elbow " is simply an, eyesore, and 

 in no wise interferes with the usefulness of a horse. The 

 swelling has its seat at the elbow, and is caused by the heels 

 of the shoe pressing against the elbow when the horse is lying- 

 down. If the capped elbow interferes with the movement of 

 the limb, it should be operated on by a veterinary surgeon. 

 Tlie heels of the shoe of a. horse suffering from this complaint 

 should be made short, and an elbow pad, of which there are 

 several makes on the market, may be applied at night. 



Capped Hock. — This complaint is similar in nature to 

 capped elbow. It is a swelling of varying dimensions at the 

 point of tlie hock. Its cause are blows on the hock inflicted 

 by the horse kicking the latter against tire stall partition or 

 heel-post. A horse's working capacity is not in any way de- 

 tracted from by this complaint, and it is of no import beyond 

 being an eyesore,
