pressure or moving the joints indicates this dis- 

 ease. In other cases the enlargement may make 

 its appearance for some time before the horse be- 

 comes lame, and in some cases it may never cause 

 any lameness, but should always be looked upon 

 with suspicion, as in the majority of cases it sooner 

 or later causes lameness. Ringbone is more dif- 

 ficult to cure on the fore feet than on the hmd 

 ones, as the pasterns are more upright on the former 

 than on the latter, and, besides, the horse's fore 

 legs have to bear two-thirds the weight of the body. 



The horse should have rest, and the shoes should 

 be removed and the foot pared level. If there is 

 heat in the part, keep it wet with the following 

 lotion by means of a bandage saturated with it: 

 Acetate of lead half an ounce and water one quart. 

 Continue this for a few days, then apply a blister 

 composed of cantharides 2 teaspoonfuls, biniodide 

 of mercury i teaspoonful and lard 8 tablespoonfuls. 

 Rub on a third of this with the fingers. It is not 

 necessary to cut off the hair if the blister is well 

 rubbed in. Let it remain on for 24 hours, then 

 wash off and rub on a little lard. Repeat every 

 second week until three blisters have been applied. 

 Keep the horse's head tied while the blister is on 

 so that he cannot get his mouth to the part. The 

 horse should have a few months' rest after this 

 treatment. If it does not cure the animal it is best 

 to have him fired by a qualified veterinarian.

 animals, especially in calves and young cattle, and

 rapidly when it finds a suitable place for develop- 

 ment. Ringworm may afi^ect any part of the body, 

 but its favorite seat is around the eyes, the face,
