 wardly. And I myfelf have tryed to diffolve fmall 

 Pieces of Gravel, by putting them into feveral 

 Kinds of Liquors, which fometimes anfwer'd my 

 Expeftation : But then fuch Liquors that had the 

 greatefc Power of dilTolving the Stones, were not 

 lafe for inward Ufe. Only this I mull obferve. 

 Juice of that the Juice of Onions approach'd neareft to the 

 Onions a Biffolvent I was feeking after. I obierve by the 

 of calculous Experiments of a late Author, the ingenious Dr.
