Not illustrated. 1830 edition.

Not volatile by any heat hitherto applied. Form soaps with oils. g. In common with the other earths, combine with acids and form sa.lts. EARTH OF A MIXED CHARACTER-iNAMELY, MAGNESIA a. Not acrid or caustic. b. Applied in substance, affects the vegetable colors. c. Nearly insoluble in water, but absorbs it. d.) Equally difficult to fuse as lime, not volatile. e.) Combines readily with acids to form salts. Combines indirectly with oils to form soap. Destitute of alkaline properties, except that (a.)

No effect on test colors. e.) Very diflicult to melt, but less so than the alkaline earths; still the alkaline earths are powerful fluxes of the earths proper, and of common metallic oxides. Not volatile by heat. g.) In their pure state, do not combine with oils to form soap. 1. Drscovnnr.-Familiarly known from the remotest ages. 2. Pnnranarron.. "(a.)
