This little book, which bears a quotation from Oliver Goldsmith on its fly leaf, "Were angels to write books they would never write folios," must be a godsend to a student who is reviewing this subject for examination. It achieves brevity by selection and arrangement rather than by compression. The author aims to give the student who is beginning the study of pharmacology a readable short account of the scope and matter of the subject without making it a mere catalogue of facts. The author says "I can hardly hope that its sphere of usefulness will compensate for the time I spent in its compilation." We sincerely hope that it will.
