JOURNAL OF THE
AMERICAN PHARMACEUTICAL ASSOCIATION
at the recent Prather Lectureship series a t Harvard University. The material is abundant in data of interest to students and teachers alike in the important functions and mechanisms by which inorganic elements affect plant life. Seven lectures are edited in splendid style covering first a survey of plant nutrition problems, the role of the nutrients, potassium and calcium, and the micronutrients, zinc, manganese, cobalt, boron, copper, iron, and molybdenum, in plant functions. This is followed by lectufes on special phases of plant physiology and plant chemistry. Included in the latter series are the absorption and accumulation of salts by cells, movement of inorganic solutes in plants, and various plant nutrition factors involved in water and sand culture media. Of great significance t o the pharmacist is lecture Number Six. Herein is a discussion of some biochemical problems associated with salt absorption, organic acids, nitrogen, protein and ion accumulation since these factors influence chemical processes throught to be important in plant biosynthesis. The author might have speculated further t o the advantage of the plant chemist. The review of the Krebs cycle and the allusion t o the importance of ammonia in plant amide synthesis are helpful. Only very general observations are offered rclative to the field of radio active isotopes as tools in plant nutrition problems. I n fact the reader finds himself wishing for more on this subject, especially data dealing with the methods. Nevertheless many useful references are included. In fact each lecture is well referenced at its conclusion. The series is accompanied by twenty-eight platephotographs showing experimental plant growth observations covering certain aspects of the text. Most of these appear t o be of material which is under experimentation in the Division of Plant Nutrition Laboratories, University of California. The pharmacognosist or plant chemist will gain much from each of Hoagland’s lectures and, more important still, he will find himself continuously in a speculative mood during his reading.-HEBER W. YOUNGKEN, JR.
International Rules of Botanical Nomenclature. By W. H. CAMP, H. W. RICKETT,and C. A. WEATHERBY.Waltham, Massachusetts : The Chronica Botanica Company. New York City: Stechert-Hafner, Incorporated, 1948. 120 pp. 17 x 26 cm. Price $3.50. Plant taxonomists and allied botanists have long had need of an up-to-date compendium of the International Rules of Botanical Nomenclature. I n this text the authors have assembled those major articles of the “Rules” initiated during the Botanical Congress a t Amsterdam (1935) together with those recommendations for further changes in nomenclature which have since been proposed by recent International Botanical Congresses. The text is not intended t o be an official printing of the format of the third (1935) edition of the “Rules.” Nevertheless i t follows the official form closely. Even the casual taxonomist will find stimulation in the many proposed recommendations. The index of conserved and rejected generic names in Appendix 111 is a decided feature.-13. it-. YOUNGKES, J R.

19.5 x 27 cm. Price $5.50. For review of Volume I see THISJOURNAL, 37, 214 (1948). Dr. Frear set UP a project at Pennsylvania State College t o catalogue all substances which have insecticidal and fungicidal properties as recorded in the literature. Like Volume I, Volume I1 gives the chemical names, synonyms, and complete forniulas as well as the results of tests on insects and fungi for chemical fungicides and plant insecticides. References and author indexes, patent lists, and R complete index of compounds listed in both volume5 are present. Keys to the literature of this type are useful t o both chemists and entomologists.

4632. For some time many chemists have wished for a n English “Beilstein” which would augment, and, to a certain extent replace, the original. This is one of the early volumes of an encyclopedia t o be produced t o answer such a need. The compilers started with a volume other than “I” in order to make available literature not so ~eadily accessible in “Beilstein” at the present. This volume, for example, covers the general literature up through 1944 and the literature concerning the structure gf compounds through 1948. The editors have kept in mind the fact that the organic chemist no longer works in isolation, and have introduced data of interest to the physicist and those working in the many fields of biology. The arrangement of compounds is simple and the system is set up so that compounds most closely related are placed together. In connection with each compound, its additive derivatives are described-the only exception being where the derivatives belong to a very important heterocyclic ring system. The generous use of tables makes i t easy for the reader to get information quickly. For example, on Pages 12-15 is a very complete tabulation of the solubility of naphthalene in a variety of solvents a t different temperatures. The table is usefully arranged and well documented. Wherever possible information is given as to the physic4 properties of a compound, its chemical preparation, its stability, analytical properties, physiological action, and the preparation of principal derivatives. Each volume carries a complete subject and formula index. The typography is excellent and the type size is conducive t o easy reading. Like “Beilstein,” the value of this work lies in its completeness. If the other volumes maintain this high standard and become available soon, research libraries and laboratories will have a gold mine of chemical information easily ;~cccssil)le.
