This is the third German edition, prepared from the fifth Danish edition, of a magnificent textbook of pharmacology. The preface lists the many sections that have been added since the second German edition. The list, too long to reproduce here, includes insect repellents, detergents, emulsifiers and macrogoles (polyethylene glycols of various molecular weights), antimorphines, new urea derivatives, carbonic anhydrase inhibitors, new antidiabetic drugs, ion exchangers, phenindione and other new anticoagulants, and tetracemin and other new chelating agents. Many other sections have been drastically revised. There is an up-to-date bibliography and a good index. In spite of the large size of the work and the rapid rate of change in its subject matter, the facts have been well assimilated and are clearly presented. The simple directness of the German does credit to the translator and will be appreciated by American readers. The book merits the attention of pharmacologists everywhere.
