Analyjis of the Air. 1 97 



cuius were diflblved in a few hours by oil of 

 Vitriol, into which there was gradually poured 

 near an equal quantity of fpirit of Harts- 

 horn, made with Lime, which caufedacon- 

 fjderable ebullition and heat. 



Tho' the remaining calx of the diftillation 

 of Tartar, in Experiment 73. run per deli- 

 fuium, and had therefore Sal 'Tartar in it ; 

 and tho* the calx of the diftilled Calculus did 

 not run per deliquiwn, and had confequently 

 no Sal Tartar in it ; yet it cannot thence 

 be inferred, that the Calculus is not a tar- 

 tarine fubftance : Becaufe by Experiment 74. 

 it is evident, that Sal Tartar itfelf, when 

 mixed with an animal calx, diftils all over, 

 fo that the calx will not afterwards run per 

 deli qui um. 



By the great fimilitude there is therefore 

 in fo many refpects between thefe two fub- 

 ftances, we may well look upon the Calculus ^ 

 and the Stone in the Gall Bladder, as true 

 animal Tartars ; and doubtlefs Gouty concre- 

 tions are the fame. 



From the great quantities of Air that are 

 found in thefe Tartars, we fee that unela- 

 ftick Air particles, which by their ftrongly 

 attracting property are fo inftrumental in form- 

 ing the nutritive matter of Animals and Ve-
