226 DISEASES OF HORSES. 



constitutional, his hide is bound from the beginning, and his urine 

 will have a sweet taste ; but if his appetite were good and his coat 

 sleek, bright, and elastic, when the urine was first observed to be 

 immoderate, the evil arises from some fault in the feeding, clothing, 

 exercise, or other management of the horse. Examine into these 

 matters, particularly into the food, and next the water. Inquire 

 whether diuretics have been given, under an erroneous supposition 

 of increasing the condition, and alter what may be amiss. If this 

 do not remove the complaint, try the following, after Blaine's direc- 

 tions : liver of sulphur, two drachms; uva ur si, four drachms; oak 

 bark, one ounce ; catechu, half an ounce ; alum, half a drachm; give 

 as a daily drink in a pint of water. 



65. Stone or gravel. Calculous concretions are not uncommon 

 in the large intestines of horses, where they grow sometimes to an 

 enormous size, lodged in one of the cells usually, and where they 

 occasion but little inconvenience, except a displacement occurs, 

 when serious evils, as colic, inflammation, or total stoppage, follow. 

 In the bladder, stone is very seldom found ; and there is reason to 

 believe, that though gravel is a common term in the farrier's list, 

 that it seldom if ever occurs ; injuries of the kidneys and bladder 

 being usually mistaken for it. 



Diseases of the Skin. 



66. Mange is a contagious disease, not uncommon among low 

 bred and badly kept horses, but which is seldom generated in those 

 properly managed. When it is the effect of impoverished blood, a 

 different course of feeding must be substituted, not heating, but 

 cooling, though generous ; as carrots, speared oats, malt mashes, 

 stable soiling, &c. When it arises in full fed horses, bleed twice, 

 lower the feeding, substituting for corn, soiling, carrots, or bran 

 mashes. Give a nightly alterative, {Vet. Pharm. 129, No. 1 or 2) 

 and dress with either of the mange dressings. (Vet. Pharm. 171.) 

 After a cure has been effected, carefully clean all the apartments 

 with soap and water. 



67. Surfeit will now and then degenerate into mange, but more 

 generally it is brought on by a fulness of habit, acted on by sudden 

 transitions from cold to heat, or heat to cold : it is likewise not 

 unfrequently the consequence of over-fatigue. If it show a dispo- 

 sition to spread, and the skin become scaly and scurfy, treat as under 

 mange ; otherwise treat as directed under want of condition. (4) 



68. Warbles are of the nature of surfeit in many instances, in 

 others they are brought on by the pressure of the saddle, which
