Excerpt from Chemical Problems and Reactions: To Accompany Stockhardt's Elements of Chemistry
This book has been prepared solely for the use of the undergraduates of Harvard College. It contains a collection of chemical problems and reactions, with references to the sections of Stockhardt's Elements of Chemistry, and also a few chapters on the chemical nomenclature and the use of chemical symbols, subjects which are not sufficiently developed in that text-book for the purposes of college instruction. In writing chemical symbols the author has adopted a uniform system throughout the volume, which, as he hopes, will be found to be at once expressive and clear. The problems and reactions cover the Inorganic portion of Stockhardt's Elements; the problems have only been extended to the section on the Heavy Metals. Beyond this, the reactions alone have been given, as it was supposed that, before reaching this section, the student will easily be able to propose problems for himself. In solving many of the problems it will be found convenient to use logarithmic tables of four places, which, with several other tables, will be found at the end of the volume. The student Is advised to remove the tables of logarithms, and paste them for use on a card. The difficulty of insuring complete accuracy in the printing of chemical formul? can be known only to those who have had to see a book of this kind through the press. Several errors have been already discovered, and discovered, but others unquestionably exist.
