DISEASES OF THE MUSCLES AND TENDONS. 197 



dried in with a hot iron. This will frequently remove wind- 

 galls, but not always. If the abscess containing the water 

 is next to the skin, they can be cured without much diffi- 

 culty; but when it is under the cellular membrane below 

 the skin, as it more frequently is, external applications will 

 not penetrate to them. 



It will hardly be worth the pains to attempt the removal 

 of wind-galls, unless there is inflammation and lameness; 

 in which case the liniment will take away the soreness, and 

 should be applied at once. 



CURB. 



This is the name given an enlargement whi?ch sometimes 

 occurs on the back of the leg, and a short distance below 

 the hock. It is produced by a strain of the strong ligaments 

 which are found at this part of the leg, or, perhaps, still more 

 frequently, by a hard blow. In the former case, it makes 

 its appearance after unusually severe exercise of some kind. 

 The nature of the injury is very -similar to that of enlarged 

 hock, described in Chapter III. 



TREATMENT. 



The treatment will be rest, and a persevering use of the 

 corrosive liniment, as directed for enlarged hock. The horse 

 will be badly lamed by curb, and must be put to work again 

 with caution. 



THOROUGH-Pm. 



Another watery enlargement that comes .on the back part 

 of the hock-joint, inside of the os calcis, (see 39, in cut on 

 page 24,) has received the name of thorough-pin. It extends 

 entirely through the connecting membrane from side to side, 

 and hence the lirst part of the name. But what resemblance 

 it bears to a pin 4s by no means apparent. 



TREATMENT. 



Thorough-pin is of precisely the same nature as wind-galls 

 and spavin, and will require the same general treatment.
