AND PHARMACOPCEIA. 471 



in diffiised swellings of the legs or other pra'ts and grease : when 

 given in moderate doses, they may be continued for several 

 days ; and a horse niay work without danger during their ope- 

 ration. Tlie diuretic alterative in our Pharmacopoeia is an ex- 

 cellent medicine for horses that are subject to swellings of th.e 

 legs, and in slight cases of grease ; but in more violent com- 

 plaints we must employ more active remedies, these being 

 adapted only to mild cases which do not prevent a horse from 

 working. However paradoxical it may appear, there Is truth in 

 the assertion that diuretics are among the most useful, and like- 

 wise the most mischievous, medicines that are given to horses. 

 They are extremely useful in carrying off the Impurities and 

 superfluous serum from the blood, thereby producing the best 

 effects in many diseases. 



Horses that have good appetites will take a diuretic in the 

 form of powder with their food, and this form should then be 

 preferred. 



DIURETIC rOWDER. 



Powdered resin and nitre, of each 4 drs. 

 INPix for one dose, and let it bo repeated daily, until a sufH- 

 cient effect is produced.

 tine, of each 4 drs. 



Powdered caraway seeds, enough to form the ball. Mix for

Diuretics should not be kept till they become hard, as they 

 often are, but be given in rather a soft state, and recently made. 

 They should also "never be so given as to operate while a horse 

 is in work, as he may thereby be prevented from staling when 

 he has occasion to do so: from neglecting this precaution, and 

 from their frequent and immoderate use, arise those mischievous 

 effects before alluded to. The kidneys are often materially in- 

 jured by them, as v/ell as the bladder.
