Cadet de Gassicourt; and Pierquinprescribe one part of balsam and two partsof aether.
It is principally employed in the form ofvapour, with the aid of an appropriate ves-sel, in chronic affections of the lungs.
BARIUM.
The following compounds of this metalare employed in medicine.
SULPHURET OF BARIUM. (VAN MONs)
R. Sulphate of Barytes, eleven parts.
Charcoal, one part.
Spirit of Turpentine,
a sufficient quantity.
Pound the sulphate with the charcoal,and moisten them with the turpentine. Putthe mixture into a crucible, and heat itgradually to incandescence ; then let itcool, and enclose it in a proper vessel.

R. Pulverized Sulphate of Barytes,
one part.Pulverized Subcarbonate of Potass,
two parts.
Mix and put them into a large earthencrucible placed in burning coals ; stir themixture in proportion as it heats, and in-crease the fire for one hour, taking carethat the mixture does not become fused.When cold, wash it with a great quantityof water, dry the residuum, and treat it
with hydrochloric acid, till it ceases to pro-duce effervescence ; then set it aside, de-cant, evaporate to dryness, and heat it toredness in an earthen crucible : then dis-solve it in water, strain the solution, eva-porate it till a pellicle forms, and set itaside to crystallize. (Bata v. ; Belg. ;Dan. ; Ferr. ; Hann. ; Hass. ; Wirtem. ;Van Mons)
Borus. ; Ross. ; Sax. ; Brugnatelli ;and Van Mons prescribe the same process,but by the moist way, that is, to boil thesulphate of barytes and the subcarbonate ofpotass with a certain quantity of water,which is to be replaced in proportion as itbecomes evaporated. The proportions are:■— Borus. ; and Sax. — one part of sulphate,two parts of subcarbonate, and four of wa-ter. — Brugnatelli — one of sulphate, twoof subcarbonate, and five of water. — Ross.— two of sulphate, three of carbonate, andfour of water. — Van Mons — eleven of sul-phate, six and a half of carbonate, andthirty-five of water.
R. Sulphate of Barytes, in powder,
four parts.Charcoal, in powder, one part.
Calcine this mixture in a crucible, witha violent heat, for two hours. Dissolvethe residuum in hot distilla! water, strain,and add gradually hydrochloric acid, till itceases to produce effervescence. Set aside,strain, evaporate till a pellicle forms, andcrystallize. (Amer. ; Austr. ; Gall. ;Pol.; Brugnatelli ; Coxe ; Van Mons)
Fenn. ; and Suec. give the same for-mula, but substitute barley-meal for thecharcoal.
