opportunity of ascertaining the efficacy of injections- iiito 

 the bladder, as recommended by Whyte, Fourcroy, and 

 myself. 



I shall conclude by observing, that it would be interest- 

 ing, to have it in our power to extend these researches, 

 to the urine of those, who live habitually on different ali- 

 ment and drinks, particularly of the acescent kind; as 

 well as to that of those, who drink waters, with mine- 

 ral alkahne impregnations. But this desirable object can 

 be only- obtained, by the concurrent exertions and atten- 

 tion of gentlemen of the Faculty, in different countries and 

 situations. In private practice it is not to be expected: 

 for here, wherever experiment is surmised to be the ob- 

 ject, mistrust and suspicion take place of professional con- 

 fidence. The use of the nitric acid, in our venereal hos- 

 pital, I hoped, would afford some useful facts, as to its 

 effects, upon the saline contents of urine; the uric acid 

 in particular. But I had not, as yet, sufficient leisure f6r 

 that enquiry; nor could I, hitherto, obtain the urine of 

 those using it, with all the circumstances, necessary to en- 

 able me, at this moment, to draw any direct conclusions, 

 from my examination of it. In many instances, a morbid 

 state of the urinary system (the urethra in particular) took 

 place. In otliel-s; the cbmbined eflects'o'f mercnry inter- 

 fered: and in all, no certainty of its not! being blendcA 

 with the urine of others, not using this acid. I could 

 not, however, help observing, that the few specimens, sent 

 to me, agreed in one particular, viz. their exceeding very 



little.
