Water, thus impregnated, abforbs hepatic air in great quan- 

 tity, and thus forms a Stronthian hepar. Marine acid, added 

 to this liquid hepar, produced a pale bluifli precipitate, accom- 

 panied with fome efFervefcence. 



Stronthian-Lime is precipitated from its folution in water 

 like the common by fpirit of wine. 



SECTION SECOND. 



Of its Relation to Adds. 



To difcover its rank in the feries of bodies fubjedted to the 

 adion of acids, I found it neceffary previoufly to examine fome 

 anomalous experiments relative to the powers of common quick- 

 lime, which, if left undetermined, would difFufe their obfcu- 

 rity over thofe which I meant to inftitute on Stronthian lime. 



About the year 1779, Mr. Sage of the Royal Academy of 

 Paris, and Doctor Demefte, afferted that quick-lime was a dif- 

 ferent earth from the calcareous ; and, to prove this difference, 

 they affirmed that lime-water precipitated a folution of gypfum, 

 and alfo of lime-ftone in the nitrous and marine acids. M. 

 Morveau, in examining the nature of various calcareous com- 

 pounds, allowed the truth of this experiment, and at that time
