MANGE. 593 



should have regular exercise and good grooming, using the wisp 

 instead of the curry-comb. Surfeit differs from mange in not being 

 contagious. 



i Urticaria, Nettle Rash, Hives, etc., 



shown by pimples, or elevations, on the skin, may go and come 

 within twenty-four hours,' generally due to a disturbance of the 

 stomach, such as gastric derangement. In any case not serious, the 

 symptoms are as follows : The horse probably not having taken 

 well to his feed (apparently all right), a few hours later the whole 

 body will be covered with little eruptions or elevations all over 

 the skin. 



__ The treatment for it should be as follows : Give a cathartic* 

 and have his body well bathed with strong, salt and water. This 

 bathing may be repeated two or three times within twenty-four 

 hours ; feed lightly, and reduce the amount of grain feed. 



This disease is caused by overfeeding and want of exercise ; is 

 always common to fat horses, and makes its appearance during the 

 spring and summer months. 



' Mange 



is another eruptive disease^ and is very contagious, and is caused by 

 the repeated attacks of minute insects which burrow into the skin ; 

 these insects are called acari, and can be easily seen by means of a 

 magnifying glass. (I include illustrations of two varieties of mange 

 parasites.) 



Causes. — In the majority of cases it is v the result of conjagibn, 

 either from coming in direct contact with a mangy horse, or it may 

 be carried by means of his harness or blankets. It is also generated 

 by uncleanliness and insufficient nourishment ; the skin, from being 

 allowed to become covered with dirt, loses, in a great measure, its 

 highly important function *in maintaining an animal in health. 



Symptoms.— Generally, the first symptom observed is the an- 

 imal's rubbing his head and neck against the ( stall or manger ; small 

 pimples appear, ^nd the hair falls off; the skin is dry and hard, and 

 upon the hardened patches may be seen small red spots. A horse 

 affected with faange is kept in a constant state «f irritation, which 

 soon reduces him in flesh-
