testicle with your left hand, also allow the hand to rest on the 

 hole where the bowel comes out; make a small cut large enough to 

 allow the testicle to slip out, and slip the clamp on over the cord ; 

 also draw up the white covering or tunics you cut through in 

 letting the testicle out, and fasten this tight in the clamp as well as 

 the cord; this will prevent the rupture from coming down. A day 

 or so after the operation it will swell some and fill up the hole 

 where the rupture comes down and the rupture will entirely 

 disappear. After four or five days it will be all right to remove the 

 clamp, and there will be no danger of the rupture coming down. 

 In the stallion it cannot be treated except by castrating in the 

 same method as is mentioned above.

DISEASES OF THE EAR. 



DEAFNESS. 



If it is of long standing nothing can be done for it, and it is 

 hard to detect it in some cases. 



Causes. — It generally comes on horses that are used where 

 there is a great deal of noise, such as artillery horses, or 

 it may be caused by a diseased state of the drum of the ear or 

 nerve. 



Symptoms. — The animal seems stubborn and cannot be taught 

 to obey the word. 



Treatment. — There connot be very much done to the horse 

 but place a twitch on his nose and pour a little sweet oil in his 

 ear every day; this sometimes helps them. 



INJURIES OR CUTS AROUND THE EAR. 



If the skin or cartilage is torn, put a twitch on the horse's 

 nose and take a needle used for sewing skin cuts and draw the 

 wound together with stitches of carriage trimmers' twine, bathe 

 it well with warm water twice a day and apply the white lotion 

 until it is healed. 



DISEASES OF THE CARTILAGE OF THE EAR. 



Causes. — This disease is generally caused from an injury of 

 some kind. 



Symptoms. — It will keep festering and breaking every month 

 or so at the place the cartilage is diseased.
