Excerpt from Plattner's Manual of Qualitative and Quantitative Analysis With the Blowpipe: From the Last German Edition, Revised and Enlarged The present Work is a translation of plattner's book, in Which nothing of the slightest importance has been omitted, While its size has been reduced as much as possible by avoiding unnecessary repetitions and by using concise language. Several new qualitative tests, a quantitative assay for mercury, descriptions of new appa ratus for measuring silver assay buttons, a complete general index, and other matters of minor importance, have been added. In the formulas of the silicates Si 02 has been substituted for Si and upward of one hundred and fifty new minerals have been intro duced. For most of these the translator is indebted to Dana's Mineralogy, Which has also rendered invaluable service in translat ing the names of the minerals. In order to secure uniformity.
