 dissoK-ed in water, and I precipitated puve siles by adding 

 an acid in excess.

 Vunquella in urinary calculi, though they ana'y.ied a very 

 great nuinl)er ; which induced me to repeat my ope.aciou 

 with the 570 grains 1 had rese"ved. As I again found siiex, 

 and in a similar propotion, in these, I felt assured, that 

 there had been no mistake in my analysis. 



From, these experiments it follows, that 100 parts of this 

 calculus contained 



Uric acid 75*33 



Phosphate of iiine 17-35
