This volume is a comprehensive exposition of the arithmetical computations with which the pharmacist may be confronted. Designed primarily as a text for a course given by the author, it may be adaptable to other situations. The author has done a thorough job of presenting the subject and has included numerous examples of practical pharmaceutic arithmetic, problems and review questions. He makes the justifiable assumption that most students have never learned or have forgotten all arithmetic and algebra except, perhaps, that two and two usually equal four. The metric system is introduced first and computations involving weights and measures, specific gravity, percentage preparations, dilution and alligation, and temperature conversion are discussed. The more complex apothecary's system is discussed in the second half of the book. The Appendix contains several useful tables. This book should prove useful as a teaching textbook in pharmacy schools, and parts of it could be used
