    * 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 bluifh 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 Acids. To difcover its rank in the feries of bodies fubjedted to the adtion 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 Dodtor 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-done 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 B attributed
