Excerpt from Practical Test-Book of Chemistry
In collecting these Tests and arranging them alphabetically, an effort is made to supply physicians engaged in practice, and pharmacists, with a ready means and safe guide for testing any substance presented for examination. And as only practical information is aimed at, the methods employed are very simple, and form a series of unpretentious experiments.
The Tests have been garnered from every available source, such as standard works on chemistry, "Proceedings of the American Pharmaceutical Association," and pharmaceutical journals; and in many instances are copied into the collection without undergoing any change. It is a recognized duty to give all authors credit for their work, but the plan and limits of this Test-book forbid particular citation of the many works consulted in preparing it; it is a book made from other books.
The spelling adopted for scientific and chemical words is that laid down by the rules of the American Association for the Advancement of Science, 1891. The temperatures are given in Centigrade.
