The author's long experience as a teacher and his reputation as a chemist are sufficient evidence that the contents of this book are well chosen to lay a broad foundation for the study of analytical chemistry. Of new matter contained in this third edition, the chapter on "Generalities on Reactions in Solution" is especially interesting. Here the author discusses in a clear, concise and non-technical way the influences which chemical equilibrium, solubility products, hydrolysis, etc., have on reactions. A short chapter on the theory of indicators has also been added. Here the modern theories for indicators are outlined, phenolphthalein and methyl-orange being used as illustrations.
In this connection, it should be stated that, although Professor Long teaches chemistry to students of medicine, the book is not written especially for medical students. Professor Long takes the ground that the elementary courses of chemistry given to medical students should not differ from
