Show 864 EGYPTIAN MIMOSA, Dub. Take of gumarabic, in coarse powder, four ounces ; —— boiling water, eight ounces, by measure : Digest with frequent agitation, till the gum be dissolved, then strain the mucilage through linen. It is very necessary to pass the mucilage throughlinen, in order to free it from pieces of wood and other impurities, which always adhere to the gum: the linen may be placed in a funnel. Mucilage of gum arabic is very useful in many operations in pharmacy ; it is also much used for properties peculiar to those substances of its own class; and ofall the gums, it seems to be the purest. Armonp Emutston. (Emulsio Amygdala Communis. EF.) Take of sweet almonds, one ounce; ————. water, two pounds and a half: Beat diligently the blanched almonds, in a stone mortar, gradually pouring on them the w ater; then strain theliquo r. Armonp Mit. zac Amygdale. L,. D.)

Take of gum arabic, in powder, two drachm s; ——— sweet almonds, blanched ——— double refined sugar, each half a drachn i ——— decoction of barley » one pint: Dissolve the gum in the warm decoction, and when it is almost cold, pour it upon the almonds previously well beaten with the sugar, and at the same time triturate them te 8 ether, so as to form an emulsion, and then filter. All these may be considered as possessing nearly the same MGYPTIAN MIMOSA. 865 qualities. They are merely mechanical suspensions of oil of almonds in watery fluids, by means either of the mucilage with which-it is naturally combined in the almonds byitself, or as. sisted by the addition of gum arabic and sugar. Therefore, on standing somedays, the oily matter separates andrises to the top, not in a pure: form, but like thick cream. 3y heat the same decomposition is immediately effected. Great care should be taken that the almonds have not become rancid by keeping, which not only renders the emulsion extremely unpleasant, (a circumstance of great consequence in a medicine that requires to be taken in large quantities, ) but like. Wise gives it injurious qualities. The almonds are blanched by infusing themin boiling water, and peeling them. The success ofthe preparation depends upon beating the almonds to a smooth pulp, and triturating them with each portion of the watery fluid, so as to form an uniform mixture before another portion be added. ‘These liquors are principally used for diluting and correcting imonious humours ; particularly in heat of urine and stranes, arising either from a natural acrimony of juices, or from the operation of cantharides and other irritating medi- cines. In these cases they are to be drunk frequently, to the quantity of half a pint, or more, at a time. |
