BEYOND THE FLYLEAF of wetting on coal are presented and the theoretical bases of the methods are critically examined. The changes in internal surface caused by heating coals to higher tempera tures are also reported. An interesting dis cussion is given of the rolation of the ultrafine structure of coal to its strength and elas tic constants. X-ray studios of coals, cokes, and chare are reported in the second group of four papers, which, together with the discussion, cover 94 pages. One of the papers describes x-ray diffraction technique for identification of noncoal minerals in coal. Another paper presents in considerable detail the experimen tal evidence in support of a turbostratic struc ture of coal analogous to t h a t proposed by R. E. Warren for carbon black. A warning is sounded in the discussion against accepting the theory in detail until much further work is done. Preliminary reports are included on iow-angle scattering of x-rays by various coals and on the crystalling- of certain highash coals. Two papers on optical properties of coal make up the third group of papers. The first of these is an interesting presentation of the data on which was based the Melchett medal lecture by C. A. Seyler in 1941. The surpris ing but apparently necessary conclusion of Seyler's work is that there exist in the coal substance components with reflecting powers differing from one another in a quantumlike manner. In the fourth group of papers, preliminary reports are given on: (1) the magnetic properties of coal, (2) the infrared spectrum of coal, (3) the use of the electron microscope for the study of coal, (4) a new technique for demonstrating the plasticity of coal, and (5) the electrical conductivity of carbonized coals. The preliminary results in most cases d o not permit evaluation of the significance of the methods of study used. Further re sults will be awaited with interest. In the foreword to the Proceedings, Evan Williams stated: "Speaking on behalf of the coal industry, I wish to say t h a t we attach the greatest importance to long range and funda mental investigations into the nature and properties of coal." Tho papers in the vol ume under review must be recognized as contributions on which the importance en visaged by Sir Evan will later be demon strated. TT TT T H. H. LOWBY
Lead Poisoning. Abraham CatUaroic and Max Trumper. xiii + 257 pages. The Williams and Wilkins Co., Baltimore 2, Md., 1944. Price, $3.00. I N this latest contribution to the evermounting literature on lead poisoning, we have a short and concise résumé of the subject. The authors have fortunately selected only the most pertinent facts necessary for a comprehensive understanding of the nature, prevention, and management of lead poisoning, and they state in the preface: " I n presenting this information, we have sought to reflect the consensus of authoritative opinion. However, on many controversial issues, we have indicated our personal opinion, based on the study of hundreds ο workers exposed to lead hazards in vaiious industries." A N D

This book reiterates again the thesis taken by many authorities—namely, that since lead poisoning may appear in t h e guise of so many nonspecific signs and symptoms, it is essential for the clinician to have a thorough appreciation of the pathological physiology and clinical manifestations of lead poisoning, as well as of the significance and limitations of findings obtained by laboratory methods. Specialists in this field will find that the treat ment of t h e subject matter is not too critical, but since there is an ample bibliography, reference t o the original source material may be had. One feature of this book which is especially desirable is the bringing together in tabular form of the data of various authors on the levels of lead in tissues, excreta, foods, etc. T h e context may be roughly divided into four major sections: (1) absorption, transportation, deposition, and excretion of lead, with a special chapter on the lead con tent of blood, body fluids, and excreta; (2) pathology and pathological physiology; (3) clinical manifestations; (4) treatment. In addition, there are also chapters of more specialized interest, such as analytical meth ods for determining lead, lead products in industry, and a discussion of the occurrence of chronic lead poisoning in various indus tries. This book should have its greatest appeal to the industrial physician.
