1800 Excerpt: ...by whose lectures numerous chemical pupils have
been formed, and whose talents in chemistry are sufficiently known
by his valuable papers inserted in the Philosophical Transactions,
has introduced the phosphorated soda into the practice of physic
with great success. 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...
