To four ounces of healthy adult urine, were added some 

 drops only of pure tartarous acid. To the same quantity, 

 one drachm of acetous acid; which brought them nearly 

 to the same standard of acidity: a circumstance always 

 attended to in the comparative trials with different acids. 

 In that with the tartarous acid, the crystals were not only 

 larger and darker coloured, but exceeded in quantity any 

 thing before observed. In that with the acetous acid, sL 

 much smaller proportion of minute crystals took place. 



EXPERIMENT VIII. 



To four ounces of urine, were added two drachms of 

 a filtered solution of acidulous tartarite of potash, of the 

 temperature 55 degrees; The usual separation and crys-* 

 tallization took place, in large proportion: the crystals, 

 however, much smaller, and less coloured, than those with 

 the uncombined tartarous acid. The two last experiments, 

 frequently repeated, presented the siame .results. ■•
