STONES IN THE KIDNEYS. 2T7 



STONES IN THE KIDNEYS. 



' These concretions, which are quite common in the horse, 

 are of a pale, dirty yellow color, elongated or conical in form, 

 and much softer than any of the other varieties heretofore 

 mentioned. " We have better evidence," says Mr. Blain, " than 

 mere supposition ; for urinary calculi (or stones in the kid- 

 neys), have been found in horses which have died with symp- 

 toms which might have been mistaken for very acute enter- 

 itis, or inflammation of the bowels. We may also suppose 

 that the early accumulations would occasion irregular and di- 

 minished secretion of urine, followed at length by a bloody 

 purulent mixture with the water, until more active symptoms 

 should arise, and carry off the horse. Concretions within tlio 

 kidneys might be removed in their early state by remedies 

 tending to decompose them in the urinary pelvis. For this 

 purpose we have mineral acids, of which the hydrochloric, as 

 holding the silicious matter in solution, is to be preferred. 

 The mineral acids pass through the body unchanged, being 

 emitted with the urine in a state of purity." 



A be'tter opportunity is afforded us of discovering calculus 

 In the urinary organs, than in any other parts ; for an examina- 

 tion of tlie urine, when placed under the microscope, will enable 

 us to detect its presence. When these deposits are ascer- 

 tained, give in every pail of water which the animal drinks, 

 two drachms of hydrochloric (muriatic) acid, which will in a 

 short time be drunk with a relish by him.
