OF THE TEXAS Сім STATE MEDICAL ASSOCIATION, SEVENTEENTH ANNUAL SESSION, HELD AT HOUSTON, TEXAS, APRIL 21, 22, 23, 1885. AUSTIN, TEXAS: PRINTED FOR THE TEXAS STATE MEDICAL ASSOCIATION. 1885. (MURIATE OF COCAINE.) AND COCAINE HYDROBROMATE PURE IN CRYSTALS. THE CRYSTALLINE FORM THE BEST GUARANTEE OF PURITY. The extraordinary demand for the Muriate of Cocaine has flooded the market with a crude product, hastily prepared, and having no appearance, even under the microscope, of crystalline structure. None of it has been free from a tinge of color, and it produces a solution more or less colored. Some of the European manufacturers have supplied a pure article, which is not only wholly free from color, but possesses a distinct crystalline structure. The price of this crystallized article has been held firmly at a higher figure than that of the amorphous salt, which, obviously, does not bear in its form the guarantee of its purity. CRYSTALLIZED MURIATE OF COCAINE. We have been the rst among American manufacturers to produce a crystallized Muriate Cocaine, and we invite comparison of our product with that of any foreign or home manufacturer. We find that the crude amorphous salt, with which the market is now largely supplied, yields only 80 to 85 per cent. of its weight of Crystals. The remainder consists of a mixture of alkaloidal salts, the most important constituent being apparently a compound closely related to Cocaine, and very possibly isomer with it, but having a much low fusing point, and assuming the crystalline form with difficulty, if at all It is clear, therefore, that the colored amorphous salts not equal in value to the crystalline, which latter is the only form in which we offer the salt itself. COCAINE HYDROBROMATE V. COCAINE MURIATE. Of all the salts of Cocaine the crystallized muriate is that which hitherto has given the most complete satisfaction; it is likely, however, to find a formidable rival in the Cy we also manufacture, andATALOGUEYDROBROMATE OF COCAINE, which ire to call the attention of physicians. Those who have used this alt declare that its effects are more powerful and more promptly produced than those of the muriate. While, therefore, we would especially commend to our medical friends these crystallized salts of Coche stace shall be pleased to supply to those who still prefer to used de in hest solutions of these salts, which are prepared with the greatest care of the strength stated below. We offer the following preparations of Cocaine, and shall be pleased to furnish on application prices and any desired information regarding their use: Cocaine Alkaloid (pure in crystals). Cocaine Citrate, 4 per cent solution. Cocaine Hydrobromate (pure in crystals). Cocaine Muriate (pure in crystals). Cocaine Muriate, 2 per cent solution. Cocaine Muriate, 4 per cent solution. Cocaine Oleate (containing 5 per cent of the alkaloid. PARKE, DAVIS & CO., NEW YORK BRANCH, 60 Maiden Lane and 21 Liberty Street. OFFICERS FOR 1885-6. PRESIDENT: E. P. BECTON, M. D., Sulphur Springs.
