Excerpt from The Qualitative Analysis of Medicinal PreparationsThe correspondence received by the author since its publication has fully justified the expectations.In revising the work the general plan of the first edition has been retained. The scheme of separation has been elaborated in order to facilitate the identification of the substances removed by immiscible solvents from an acid solution, and procedures have been given for separating the alkaloids which are commonly found together in mixtures. A complete scheme for the identification of metals and inorganic acids has been added, and a method for identifying volatile oils proposed by Nelson has been included in the chapter on Liniments.Few changes have been made in the second portion of the work. The directions originally proposed have stood the test of many years of experimental work, and except for an amplification of the procedure for examining emul sions and for identifying the volatile constituents of liniments and the addition of a section on Chewing Gums, that portion of the book remains practically as it was in the first edition.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
