90 THP] PRACTICE OF VETERINARY MEDICINE. 



a cure, and unless treated energetically a failure may be 

 expected. A laxative should be given, to be followed by 

 pretty strong diuretics. In the meantime, the diet should 

 be carefully attended to, and should consist of light and 

 easily digestible food, given at regular intervals and in 

 regular quantities. If there is any local irritation, it is to 

 be allayed by the judicious use of fomentations. As a local 

 application, the ungt.iodi. comp., strong or weak, as judgment 

 dictates,may often be of great service; or corrosive sublimate, 

 as before mentioned, is in some cases useful ; and the parts 

 maybe touched occasionally with a pencil of nitrate of silver, 

 the healing process being accelerated thereby. Poultices are 

 highly beneficial, but it is very difficult to apply and retain 

 a poultice at this part. The treatment should be persevered 

 in, or a failure may be apprehended, in which event it may 

 degenerate into a case of elephantiasis. 01. morrhua applied 

 daily with a feather will prevent the attack of flies. Tr. 

 opii, in conjunction with glycerine, makes a good mixture to 

 allay irritation of the parts, as well as lubricating and keep- 

 ing them soft. A horse in season should have a laxative, 

 but if not in season, a brisk cathartic may be given. 



Sallenders. — This condition occurs in the flexures of the 

 hock, and with that exception it is exactly the same condition 

 iis mallenders. Its pathology, cause, symptoms, and treatment, 

 are the same as mallenders. Of the two conditions, sallenders 

 occurs probably with greater frequency than mallenders. 



Prurigo, or Pruritis. — This is a disordered condition of 

 the skin, caused by functional derangement of the nerves of 

 the part (neurosis). It occurs more particularly about the 

 roots of the tail and mane. It is a very trivial disease, but 

 is very hard to cure. 



Causes. — Generous feeding with irregular exercise, bad 

 grooming, etc., are the causes of pruritis. It is oftenest seen 

 during the hot months.
