500 DISEASES OF THE URINARY ORGANS. 



>vhen injected at once into the bladder, they have proved 

 irritating and otlierwise hurtful in a high degree. Dupuy 

 injected vinegar and water for a long while, but was at 

 length compelled to desist in consequence of both the 

 bladder and hind quarters being seized with paralysis. And 

 of all lithontriptics, this, says D^Arboval, is in most repute. 

 It has been ascertained at Alfort that it is capable of effect- 

 ing the dissolution of calculi out of the body, the harder the 

 stones the more acid being required ; some demanding equal 

 parts, with an elevation of the temperature of the mixture 

 to 90 degrees of Fahr. If ever success should attend this 

 mode of treatment, it will probably be, as D'Arboval justly 

 adds, in the case of s?nall calculi. Professor Morton says 

 in regard to it, " The acetic, nitric, or hydrochloric acid, 

 may be successfully employed. I should prefer the last- 

 named, from the fact that it is the same as that met with in 

 the alimentary canal, although I believe either of the others 

 would prove as efficacious.^' And the Professor makes re- 

 lation of a case, in which the solution appeared to have 

 succeeded, in the hands of Mr. R, Hutton, Y.S., Great 

 Yeldham. 



The horse was eight years of age, and had for long suf- 

 fered much difficulty in urinating, and of late had gradually 

 fallen away. Mr. Hutton '^ detected two calculi in the 

 bladder,^' in addition to subulous matter. His owner ob- 

 jucting to operations, Mr. Hutton at once determined to 

 try hydrochloric acid ; of which he gave, at first, 5iij of the 

 acid in three gallons of water, which after a little difficult}', 

 the horse freely drank. There being but little improvement 

 after a fortnight, a purge was given, and in three days the 

 acid had again recourse to, the dose now being 5vj to three 

 gallons of water, thrice a day. This had the effect ; a large 

 quantity of calcareous matter was voided with the urine, 

 and the appetite improved. The treatment was persevered 

 in for four months, with occasional purging. The horse got 

 well, and now " stands his work well.''^
