Its medical qualities are the fame as those of Glauber's and Rochelle salt. It deserves preference for weak stomachs, &c. by being less nauseous is to taste, and hardly perceptible if taken in water-gruel or iveal-broth.--Were it not for its high price, it would probably be in general use, instead of the two other above-mentioned salts.--Edit. 3. Phosphat of ammoniac affords crystals, permanent in the air, of quadrangular columns, possessed of an ammoniacal taste, readily dissolved by water, melting in the fire, and then parting with their ammoniac, while the phosphoric acid remains ( 873.--This salt and the preceding exist both in human urine. It is decomposed by both the fixed alkalis. '. 876. -. 4. Phosphoric acid, saturated with calcareousearth, or the phosphat of lime, is void of all taste, and absolutely insoluble in water. If, therefore, 2 some some phosphoric acid be dropped into lime-water, a white precipitate is produced; but, by an excess of the acid, this combination becomes capable of solution in water; and if the fluid be saturated with any alkali, it is not lime, but phosphat of lime, that is thrown down.--The habitudes of phosphated calcareous-earth, in a heat strong enough for fusion, are entirely similar to those of calcined bones.--The calcareous-earth has a stronger affinity with phosphoric acid than the alkalis. On this account limewater produces always a precipitate, when added to solutions of phosphated neutral salts. 877 5. Phosphat of magnesi...
