Abstract

(1) THE “Preliminary Chemistry” by Mr. Bausor, which is issued by the University Tutorial Press, provides, as the preface states, a course of simple experiments for beginners in chemistry, from which most elementary principles of the science are deduced. There are six chapters dealing with air, water, carbon dioxide and lime, salt and hydrochloric acid, sulphur and its acids, and, finally, carbon and combustion. Each chapter is furnished with a summary, a set of questions, and some practical exercises. The experiments are simple in character so as to be well within the capacity of a schoolboy, and the sequence is so arranged as to illustrate fundamental ideas in a clear and logical fashion. For the most part they run on familiar lines. It may be pointed out that the definition of one term by using another, which is left undefined, does not leave the matter much clearer. “If by its conversion into ice or into vapour a new body had been produced differing in constitution from the water, we should no longer have been dealing with a physical change.” No doubt the orthodox way of beginning a book on practical chemistry is to direct attention to the fundamental distinction between chemical and physical changes; but is it really essential to start with it? Could not the question be more easily answered after a certain number of chemical changes had been observed?
