Riassunto

Excerpt from Manual of Qualitative Chemical Analysis

A series of very brief analytical tables has been appended to this edition. These tables are borrowed, with some changes, from Mr. Vacher' 8 English edition of 1869. No such tables, however elaborate, can take the place of Fresenius' systematic course, in the real work of the careful analyst, but they may be made very serviceable to the beginner in enabling him to survey his ground, as well as to the experienced chemist, when, being out of practice, he may need a brief outline of the order of operations to sharpen his memory.

In form the book is quite changed by the use throughout of the language and notation of modern chemistry a change called for by the universal adoption of the New System, as well as by its inherent advantages. For the convenience of the student, various developed formula are given on pages 49 and 50 and innumerous foot-notes. In these formulae each dash, either horizontal, vertical or inclined, indicates a bond or unit of quantivalence, and implies chemical combination between the atoms or groupings whose symbols are thus connected. The sign and period are used to express molecular combination, i.s., combination not amenable to the usually received quantivalences, as in case of crystal water.
