I diftilled in the fame manner, as the 

 above mentioned calculus-, fomeftones taken 

 out of a human gall bladder, they weighed 

 52 grains, fo their bulk was equal to | part 

 of a cubick inch, as I found by taking their 

 ipecifkk gravity. There was 108 cubick in- 

 ches of elaftiek Air raifed from them in di- 

 ftillation, a quantity equal to 64S times their 

 bulk ; much the fame quantity that was 

 raifed from the calculus. About f part of 

 this elaftiek Air was in 4 days reduced in- 

 to a fix'd Mate. There arofe much more 

 oil in the diftillation of thefe Stones, than 

 from the Calculus, part of which oil did 

 arife from the Gall which adhered to, and 

 was dryed on the furfaces of the Stones, 

 which oil formed large bubbles, like thofe 

 which arofe in the diftillation of Deers Horn 



A fmall Stone of the Gall Bladder, which 

 was as big as a Pea, was difiblved in. a Lix- 

 ivium of Sal Tartar in {even days, which 

 Lixkium will alfo diffolve Tartar s yet it 

 wi'i not diffolve the Calcitlus y which is more 

 firmly united in its parts. 



A quantity of Calculus equal to one half 

 of what was diftilled, viz. 1 15 grains, did,
