[old form 2 To the Spirit of Phosphorus, contained in a graduated bottle, add the Oil of Anise and Glycerin, and mix them by repeatedly inverting the bottle, until they form a clear liquid. Then add Aromatic Elixir, in several portions, gently agitating after each addition, until a transparent liquid is obtained, and the product measures 1000 C.c. [old form 2 pints]. Keep the product in dark amber-colored, well-stoppered bottles, in a cool and dark place. Each cubic centimeter of Elixir of Phosphorus represents about one-fourth milligramme (0.00025 Gm.) of phosphorus. QUESTIONS ON CHAPTER XXIII. ALCOHOLIC SOLUTIONS. In pharmacy, what are spirits?

ETHEREAL SOLUTIONS. Collodia. Collodions. COLLODIONS are liquid preparations intended for external use, having for their base a solution of pyroxylin, or gun-cotton, in a mixture of ether and alcohol. (For a description of the properties of pyroxylin and collodions, see Part V.) Collodions are applied to the skin by means of a soft brush, and when the ether and alcohol evaporate, a film is left on the surface, which either acts as a protection or brings a medicating agent in contact with the epidermis. are official. Four collodions Collodium. Collodium Cantharidatum. Collodium Flexile. Collodium Stypticum. 30 Gm. Pyroxylin; 750 C.c. Stronger Ether; 250 60 Gm. Cantharides, No. 60 Powder; 85 Gm. Flex- 20 Gm. Tannic Acid; 5 C.c. Alcohol; 25 C.c. To the Pyroxylin, contained in a suitable bottle, add the Ether, and let it stand for fifteen minutes; then add the Alcohol, and shake the bottle until the Pyroxylin is dissolved. Cork the bottle well, and set it aside until the liquid has become clear. Then decant the clear portion from any sediment which may have formed, and transfer it to bottles, which should be well corked. Keep the Collodion in cork-stoppered bottles, in a cool place, remote from lights or fire. 22 22 337 Pack the Cantharides firmly in a cylindrical percolator, and gradually pour Chloroform upon it, until the powder is exhausted. Recover the Chloroform by distillation from a water-bath, and evaporate the residue, in a capsule, on a water-bath, until it weighs 15 Gm. [old form 231 grains]. Dissolve this in the Flexible Collodion, and set it aside to become clear by settling. Finally pour off the clear portion from any sediment which may have formed, and transfer it to bottles, which should be securely corked. Keep the Cantharidal Collodion in cork-stoppered bottles, in a cool place, remote from lights or fire. Weigh the ingredients, successively, into a tared bottle, and mix them thoroughly. Keep the product in cork-stoppered bottles, in a cool place, remote from lights or fire. Introduce the Tannic Acid, Alcohol, and Ether into a graduated bottle, agitate until the Tannic Acid is thoroughly incorporated and partially dissolved, then add enough Collodion to make up the volume to 100 C.c. [old form 3 fl. oz. 183 min.], and shake occasionally, until the Acid is completely dissolved. Keep the product in cork-stoppered bottles, in a cool place, remote from lights or fire. CHAPTER XXV. OLEAGINOUS SOLUTIONS OR EXTERNAL APPLI CATIONS. Linimenta. Liniments. THESE are solutions of various substances or mixtures in oily or alcoholic liquids containing fatty oils, intended for external application, and usually applied with friction and rubbing of the skin. There are nine official liniments, of which three are made with a fixed oil as the base, five with alcohol as the principal liquid, and one contains oil of turpentine. They are classified as follows: Proportions. 350 C.c. Ammonia Water; 50 C.c. Alcohol; 600 C.c. Cotton Seed Oil. Equal volumes Solution of Lime and Linseed Oil. 200 Gm. Camphor; 800 Gm. Cot- 50 Gm. Camphor; 950 C.c. Fluid 70 Gm. Powdered Soap; 45 Gm. 650 Gm. Soft Soap; 20 C.c. Oil of Lavender Flowers; 300 C.c Alcohol; Water, to make 1000 C.c. 30 C.c. Volatile Oil of Mustard; 200 C c. Fluid Extract of Mezereum; 60 Gm. Camphor; 150 C.c. Castor Oil; Alcohol, to make 1000 C.c. Linimentum Terebinthinæ. Oil of Turpentine. 650 Gm. Resin Cerate; 350 Gm. Oil of Turpentine. |
