20 THE VETERINAEIAN 



Symptoms : A puffy swelling located in front and on 

 the inside of the hock, varying from the size of a walnnt 

 to that of a man's fist. It very seldom causes lameness, 

 but is a serious disfigurement and blemish. 



Treatment: Treatment is not satisfactory unless 

 taken in its first stages and when the animal is young. 

 If there is heat, pain and swelling, apply cold water or

 use the following prescription : Tincture of Iodine, two 

 ounces; Gum Camphor, two ounces; Gasolene, one pint. 

 Mix and shake well before applying with a nail or tooth 

 brush twice a week. 



I may add that I have derived some wonderful results 

 in treatment of Bog Spavin with the above mentioned 

 prescription in both young and old animals, and per- 

 haps it will be well to use it on both .young and old 

 animals in both acute and chronic forms of Bog Spavin.

 the autumn on the skin and hair of the horses. These 

 eggs on becoming hatched (in from 20 to 25 days) pro- 

 duce small worms which irritate the skin by their move- 

 ments and thus cause the horse to lick them off and to 

 take them into his mouth, with the result that they gain 

 access to various parts of the intestinal canal. The bot
