» I diftilled in the fame manner, as the 

 above mentioned calculus, fomeftones taken 

 out of a human gall bladder, they weighed 

 52 grains, (o their bulk was equal to i part 

 of a cubick inch, as I found by taking their 

 fpecifick gravity. There was 108 cubick in- 

 ches of elaftick Air raifed from them in di- 

 ftillation, a quantity equal to 64S times their 

 bulk i much the fame quantity that was 

 raifed from the calculus. About % part of 

 this claftick Air was in 4 days reduced in- 

 to a fix'd Irate. There arofe much more 

 oil in the diftillation of thefc Stones, than 

 from the Calculus, part of which oil did 

 arifc from the Gall which adhered to, and 

 was dryed on the furfaces of the Stones, 

 which oil formed large bubbles, like thole 

 which arofc in the distillation of DecrsKorn 



p. i?7. 



A final! Stone of the Gall Bladder, which 



was as big as a Pea, was difiblvcd in a Lix- 

 ivium of Sal Tartar in feven days, which 

 Lixi'. ium will aifo diffolvc Tartar; yet it 

 will not di Halve the Calculus, which is more 

 firmly united in its parts. •<*
