gravate the complaint; for by flimiilating the kidneys, 

 and driving more blood to them, they heighten the 

 inflammation. Inflammation of the kidneys may 

 be diftinguiflied from the common cafes of llrangury, 

 by the fymptoms of fever that accompany it, and 

 by the very high colour of the urine. Bloody urine 

 is fometimes made after very fevere exercife ; here 

 likewife diuretics are hurtful : plenty of mild dilut- 

 ing liquids are the moft proper means of cure. 



Diuretics, though of great fervice in the cafgs above 

 noticed, fliould never be given too flrong, or too 

 long continued; otherwife they may bring on a weak- 

 ened fl:ate of the kidneys. Various fubftances are 

 ufed as diuretics ; and whatever is ufed as fuch, ads 

 with infinitely more certainty in the horfe than in 

 man : hence thefe medicines are much more fre- 

 quently employed in the one than the other. Water 

 given to a horfe who has been deprived of it for 

 twenty-four hours, proves a very flrong diuretic. 

 Nitre, mixed with the food, is frequently ufed as a 

 mild diuretic, and, when it does not gripe, is a very 

 good one. Ilefin is likewife a very common diuretic ; 

 but it is fl:rong and adive, and, whenever given, an 

 interval of three, four, or five days, according to the 

 force with which it ads, fliould be allowed between 

 each dofe. But, to prevent the fatal efieds of giving 

 improper fubllances, I would recommend, that when- 

 ever anadive diuretic is wanted,
