![ACACIA GUMMI. Syn. Acacia U.S. X., Gomme Arabique, Gomme du Senegal, Fr. Cx., P. Belg. IV., P. Ital. V., F. E. VIII. A gummy exudate from A. Senegal, Willdenow (N.O. Leguminosce), | and other species, either colourless or with yellowish tint.—B.P. ’14. The gum consists, in the main, of a mixture of Alkali Arabinates. Soluble almost completely in water : insoluble in Alcohol. As emulsifying agent for oils, Powdered Gum Acacia is used, e.g., in Mistura Olei Ricini {B.P. ’14), the usual proportion being about 1 of Gum to 4 of oil. Less suffices in some cases. For suspending resinous ingredients of Tinctures vide Tincturse. For its use as a pill excipient, vide Pilulae. Mucilago Acacise (B.P. T4).—Gum Acacia 4, washed to re¬ move any adherent dust, dissolved in water 6. This quantity measures about 8|. Benzoic Acid 0 • 1 % added will keep it. Incompatibles.—Alcohol, Mineral Acids, Borax, Ferric Salts, Oxalic Acid and most Lead Salts. Bismuth Carbonate should not be suspended with Acacia Mucilage. Tragacanth answers better. Mucilago, U.S. Contains Gum Acacia 35, Sodium Benzoate 0-1, Water to 100. Potion Gommeuse. Fr. Cx. Gum Acacia Powder 1, Syrup 3, Orange Flower Water 1, Water 10, parts by weight. Gum Acacia Solution for Intravenous Injection. Syn. Solutio j Salina cum Acacia, U.C.H. and St. Th. H. (6% Gum); Injectio ] Salinje et Gummi Acacia:, R.N.H. (7% Gum). Gum Acacia 70 Gm., Sodium Chloride 9 Gra„ Water to 1 litre. : The solution to be sterilised after straining through fine linen. The addition of any antiseptic is not desirable. Gum Acacia Sterules are prepared. The contents of one Sterule, diluted to 250 Cc. with boiled water, produces a 7% injection in Normal Saline. jjseSt-j£o raise blood pressure after loss of blood, e.g., from a wound of the femoral artery. Many such cases could be saved if the blood pressure could be kept up for 24 hours or so. I he solution has the same viscosity as the blood and a content of colloids with osmotic pressure equal to that of the blood, hence aftei its injection there is little tendency for water to pass into the tissues. Large quantities may be used. In surgical shock the method has been found of great value. Solutions of 5% or over will restore permanently the due to loss of blood.—Sir W. M. Bayliss, B.M.J. 1./17,564 , n./i7,808 , i./i8,553f i./io,262. Jl. Ph. & Exp. Ther., Mar. 1920, p. 29. r*9°/ has also be<m suggested.—-Med. lies. Counc., B.M.J. i.[iy,1*06.

Normal Saline was first proposed, but it disappears from th0 c:iu m aion m - - - minutes. A colloid with an osmotic pressure equal to that ol the bloou ooiioiob must be added. Good gum answers the purpose well.—Sir W. M.
