274 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS growth in the membership of the Society. Several new members, some pre-eminent in their different spheres, had helped to make prog- ress in this direction not merely a matter of numbers but also of qual- ity and variety. (b) Mr. Wells then went on to detail the activities of the Society during the past year and mentioned the papers read by W. H. Dicken M.Sc., of General Metallurgical & Chemical Ltd., Dr. William Mit- chell of Stafford Allen & Sons Ltd., and the Symposium on Deteriora- tion 'in Cosmetics & Toilet Prepa- rations and the Olfaction Sympos- ium. Finally, mention was made of the highly successful social even- ing. (c) Mr. Wells then outlined the progress that had so far been made with the Society's ]ourna/. He told the meeting that the quotation for printing had been received and accepted. Editorial papers had been submitted for publication by J. Pickthall, Dr. R. Matalon, and Messrs. Chadwick and Pears. Ad- vertising revenue would be forth- coming. Finally, he mentioned that he was receiving valuable sup- port and assistance from Messrs. Holmes, Pickthall, and Bather. NECROLOGY Dan F. Nealon, Vice-Presideht of the National Toilet Company of Paris, Tenn., died on January 27th at the age of 54, of a heart ailment. Born and schooled in Chicago, he was a graduate of the University of Illinois. Originally he started work for the Walgreen Company, then moved to the Frank Betz Company joining the National Toilet Com- pany in 1923. He was known to many through years of writing for the trade jour- nal, Drug and Cosmetic Industry, where he carried a monthly feature of news items. After the passage of the 1938 Food, Drug and Cosmetic Act, he became active in establish- ing mercury skin bleach creams on a scientific basis and as a result was the author of a series of papers on the subject. As recently as May, 1950, he addressed the Society of Cosmetic Chemists on the "His- tory and Scientific Background of Bleaching Creams" illustrating his talk with photographs and slides describing his method of measur- ing the bleaching results. Dr. Owen Gibbs says of him-- "Undoubtedly the key to Dan Nealon's life lay in his outstanding personal charm. Although he was fundamentally a very modes{: man, yet he radiated his warm message of simple friendliness so clearly that virtually everyone responded. It was always a pleasure to be in his company for his quiet sense of fun stemmed from a very deep apprecia- tion and love of his fellow men. He was indefatigable in his efforts to help

NECROLOGY 275 those around him, which he did without a single selfish thought, in- deed, without sufficient heed for his own health. The list of his various activities, civic and other- wise, is but the bare bones of a life, unfortunately cut too short, which was richly clothed by the warmth and devotion to the welfare of any- one who asked his help. And many did." He was a member of the American Chemical Society (for many years a Councillor of the Memphis Sec- tion), the Society of Cosmetic Chemists, Masons, and Knights Templar. He is survived by his wife, two children, and a grandson, the child of a daughter Virginia who died about 2 years ago. BOOK REVIEWS PHYSICAL METHODS IN CHEMICAL ANALYSIS, Volume I, edited by Walter G. Berl, 664 pages, size 6 X 9 inches, illustrated and indexed. Academic Press Inc., New York 10, N.Y., 1950. Price $12. This is the first of two volumes. Its subject matter includes "all methods dealing with the inter- action of radiation with matter in addition to mass spectrometry." Twelve sections in all, with as many authors, comprise the text. More qualified scientists could not have been found to write any book. Volume I is not intended to be an elementary manual on physical methods, rather it is an advanced reference describing the latest in- novations in physical methods as tools of the analyst. Each section follows a fixed pat- tern in presentation, ending with literature references. The book is well made and easy to read. No printers errors were noted by this reviewer. It appears to be fairly priced. While a reference of this type has limited use in the toilet goods in- dustry, there are quite a few labora- tories which will be richer as a re- suit of its presence in their libraries. --M.G.DEN. THE ELECTRON MICROSCOPE, by D. Gabor, 51/4 X 8 inches, 157 pages, indexed. Published by the Chemical Rubber Publishing Com- pany, Brooklyn, N.Y., 1948. Price $4.75. ' This monograph began as a lec- ture delivered before the Cam- .bridge University Physics Society in 1943. Dr. Gabor presents the fundamental principles of electron optics in precise form. He has not sacrificed accuracy of description for the sake of popular presentation. The difficulties inherent in working with electron microscopes are care- fully outlined. Readers familiar with ordinary optical microscopes will appreciate these intricate prob- lems that arise when electron beams are focused by magnetic or electro- static lenses. The 63 mathematical equations diktributed throughout the mono- graph need not deter a reader un- versed in physics. Dr. Gabor makes an adequate interpretation of their physical meaning in his text. In the ten pages of Chapter 10,
