SECTION THIRD. 



Of the Jffinities of Stronthtan. 



Stronthian lime-water, poured on a folution of tartar vitrio- 

 late, immediately formed a precipitate, and fo it did in the 

 folution of glauber's fait and vitriolic ammoniac ; hence its affi- 

 nity to vitriolic acid is fuperior to that which any alkali bears to 

 this acid. 



It alfo formed a precipitate in the folutions of common fele- 

 nite, epfom and allum ; hence the affinities of common lime, 

 magnefia and argill, to the vitriolic acid, are inferior to thofe of 

 this earth. 



But barytic lime-water decompofes the compound of vitriolic, 

 acid and Stronthian, and alfo the combinations of this earth with 

 the nitrous, muriatic and acetous acids. 



Hence the affinities of Stronthian feem to be the fame as 

 thofe of barytes, but inferior in degree, though fuperior to thofe 

 of common calx.
