Chemical Problems, with Brief Statements of the Principles involved. By James C. Foye, Ph. D. New York: D. Van Nostrand. Pp. 141. 50 cts.
The value of problems as means for securing accuracy in a knowledge of the subject, and as tests for attainments, is generally recognized by the best educators. The present work was prepared to meet a need felt by the author, who is a professor in Lawrence University, Wisconsin, in instructing his classes. Its plan is very simple. After defining the terms used, and briefly stating the principle to be illustrated, a typical problem is solved, and from the solution a formula of general application is deduced, which is followed by problems to be worked by the student. These, as a rule, bear upon the fundamental principles of chemistry.
Steam-Heating. An Exposition of the American Practice of warming Buildings by Steam. By Robert Briggs. New York: D. Van Nostrand. Pp. 108. 50 cts.
Unless some application of electricity is devised to supersede it, steam is, in all probability, destined to be the agent by which our houses will be heated in the future. Aside from its superior cleanliness as compared with most other methods of heating apartments, the facility with which the warming and ventilation are managed, when it is once established, is a strong recommendation in its favor. Mr. Briggs's treatise includes a great deal that the builder and householder will find useful on the subject, particularly on the practical side.
