_Ammonol._—This preparation is said to be Ammoniumphenylacetamid on one portion of its label and directly under it is said to contain 240 grains of paracetyl-phenetidin in each ounce. _Phenalgin_, marketed as an ammoniated phenylacetamide, is labeled as containing 50 per cent. of acetanilidum. _Benzosalin._—Methyl benzoyl salicylate occurs as a white crystalline powder having a slight aromatic odor and taste. The substance melts at from 84 to 85° C. It is nearly insoluble in water, but is soluble in 35 parts of alcohol and is readily soluble in chloroform but somewhat less so in ether. (_Phar. Centralh._, 1906, p. 1053.) _Borovertin._—This is the name that has been applied to hexamethylene tetramine triborate. The substance occurs as a yellowish white powder readily soluble in water and having a distinctly bitter taste. It may be given in doses of from 1 to 4 grammes daily. (_Phar. Centralh._, 1906, p. 928.) _Castor oil in form of powder._—A recently issued German patent describes a process for preparing a supposedly active preparation of castor oil in powder form. This is accomplished by the addition of light calcined magnesia to an emulsion of castor oil, or by adding a specific quantity of castor oil to the same weight of calcined magnesia that has been moistened with distilled water, and drying the resulting mixture and powdering the residue. (_Phar. Centralh._, 1907, p. 65.) _Cystopurin._—This is said to be a combination of one molecule of hexamethylene tetramine with two molecules of sodium acetate. It occurs as white, nearly tasteless crystals that are readily soluble in either hot or cold water. Cystopurin may be administered in doses of 1 or 2 grammes three times a day. (_Phar. Zeit._, 1907, page 48.) _Forgenin._—This is said to be tetra methyl ammonium formiate and responds to all of the known reactions for formic acid compounds. It is being recommended, in small doses, as a heart tonic. (_Phar. Zeit._, 1907, page 48.) _Levurinose_ is a name given to a yeast that has been desiccated by means of a current of cold air so as to preserve the individual yeast cells intact. This preparation has been recommended to be used in affections of the skin, such as acne, eczema, furunculosis, urticaria, etc. (_Phar. Zeit._, 1907, page 47.) _Mistura Strzyzowski_ is the formidable name, applied in Austria, to a mixture containing ferric pyrophosphate, quinine hydrochloride and sodium bromide. This mixture is directed to be prepared as follows:— Sodium bromide 8·00 is dissolved in distilled water, 40·00; syrup of orange peel, 20·00; alcohol, 10·00. Mix and add a solution of quinine hydrochloride, 1·00 in distilled water, 40·00; and syrup of orange peel, 20·00. Mix, and then add the following, prepared by slightly warming: Ferric pyrophosphate with ammonium citrate, 4·00 in distilled water, 40·00. Mix, and add syrup of orange peel, 40·00. Dose, one to two teaspoonfuls, with water, two or three times a day.
