A New School Chemistry

Abstract

ALTHOUGH the subject matter of this elementary text-book is not new, the author's presentation of it is clear and attractive, the chapters being divided into descriptive text, practical exercises, and examination questions. Short summaries and experiments for demonstration are sometimes ap pended, and the time required for each exercise is also given. This should be very helpful to the teacher in organising his practical classes. In the section on chemical theory, the combination of the two equations representing the effects of pressure and temperature on the volume of a gas (p. 137) may cause some difficulty, and the reason for introducing the idea of ‘molecules’ is not quite clear; otherwise the reasoning which leads up to the determination of atomic weights seems to have been admirably condensed.
