Excerpt from Practical Organic Chemistry
The present volume is an enlarged edition of that published in 1887, and has been completely rewritten. The preparations have all been carefully revised, some of the former ones omitted and many new ones introduced. The chief additions are the introductory chapters on organic analysis and molecular weight determinations, and an extension of the appendix.
The book does not aim at being a complete laboratory guide, but is intended to provide a systematic course of practical instruction, illustrating a great variety of reactions and processes with a very moderate outlay in materials and apparatus.
The objection may be raised that the detailed description of processes makes no demand upon a students resourcefulness or ingenuity. It must be remembered, however, that the manipulative part of organic chemistry is so unfamiliar to the elementary student that he requires minute directions in order to avoid waste of time and material. Until he has acquired considerable practical skill he cannot accomplish the experimental work requisite for research, and repeated failures will be apt to destroy his confidence in himself.
To satisfy, to a legitimate extent, the prejudices of certain examining bodies, who still adhere to the old system of testing a students knowledge of practical organic chemistry by means of the qualitative analysis of certain meaningless mixtures, the special tests for some of the more common organic substances have been inserted.
