BOOK REVIEWS 319 Scientific Section, is not mentioned. The authors state in their fore- word that they have not considered all the cosmetic materials, limiting themselves to approximately 1000 ingredients. It is unfortunate they did not divide the book into two parts, one on essential oils and per- fume materials, then putting all' cosmetic ingredients together in another section. Many questionable listings are present. To name a few--lyco- podium, calcium chloride, maleic anhydride, mercurochrome, ferric ferrocyanide, oxalic acid, turpen- tine, potassium and sodium iodate, and oil of tansy (and some other medicinal essential oils). In general, the proofreading is good. However, the word Xerol is spelled Zerol at least two times (pages 141 and 334), and sulforates for sulfonates (reference 80). There is some inconsistency in the entries. Thus cetyl alcohol is listed under "alcohols," but stearyl alcohol is under "stearyl" alcohol traga- canth is described under "gums," but acacia is under "acacia." The melting point given for cetyl and stearyl alcohols and stearic acid is for the c.p. material, though the commercial grade is the one used and mentioned. The latter have dif- ferent melting points. Eosine is badly handled am- monium, sodium, and calcium thio- glycolares are not given though the acid is described. It is unfortunate that Behrman's work on thiogly- colates is not mentioned. The .toxicity of 2-methyl 2-4 pentanediol is known but not given. The generalities under "soap, powdered" do no credit to the authors. The pH of water suspensions of talc are not correctly reported. They are usu- ally over pH 8 unless the talc is acid washed. One suggests the authors find another word for "cosmeticJan" on page 164. The instability of aluminum citrate solutions is not mentioned under its properties. The authors will be interested in knowing that there is an aluminum phosphate that is water soluble. The title "estrogenic hormone" is badly handled. No mention is made of estrogens derived from vegetable sources. The monobenzoate is not commonly used in cosmetics. How does one obtain glycerin from tri- stearin during the manufacture of either cold or vanishing cream ? The literature is freely quoted, both good and badly executed litera- ture. What is the point in quoting bad literature--just to have a lot of references ? Without an index, one has to look for a listing under several possible headings. Too often the item sought is not listed at all.--M. G. DENAVARRE. OP. OANIC ANALYSIS, V•l. I, edited' by J. Mitchell, I. M. Kolthoff, E. S. Proskauer, and A. Weissberger.

Between the advisory and edi- torial boards of this book, one could hardly find another name important in organic analytical circles. Yet the various chapters are written by almost a dozen other experts. This book is aimed at the gap in university level training in chemical analysis. Except for a minor inconsistency in using both terms glycerol and glycerine, (pages 43-44) the editors have maintained a uniformity in s.tyle between the several contribu- tions. Numerous perfumery and cos- metic materials are included in the analytical methods. The book looks very useful to analysts.--M. G. DENAvARRE.

The work is consistent with their previous writings. Some may consider portions of the book as too rudimentary. Other parts suggest an incomplete familiarity with the U.S. soap industry at which the book seems to be slanted. The writers' forte appears to be in their ability to translate into lay language, the complex phenomena that take place in soap production.. Sometimes scientific exactness is lost in putting a thesis into com- paratively easy reading--a certain liberty must be allowed in such cases. One questions the statement that ethyl (and amyl) salicylate is alkali resistant on page 407. Also the suggested use of ethyl alcohol in superfatting, must mean cetyl or stearyl alcohol. The superfat is not always added to the fat charge be- fore adding the lye. The formula on page 483 for golden shampoo, though quoted from another author has doubtful hair tinting value. While glycerin is spelled "glyc- erine" through the book, several places on pages 320-321 it is spelled as ".glycerol." This is a minor in- consistency. This reviewer feels that the last part (D) of the book dealing with special soap products is the weakest. However, the other parts of the book more than offset it. In general the discussion of raw materials is good. Many useful diagrams and tables supplement the text. The book seems a bit high priced until one realizes its limited market. Hence this reviewer looks forward to the completion of Volume II.--M. G. DENav^RRE. COMPREHENSIVE INORGANIC CHEM- ISTRY, Vol. I, edited by M. Cannon Sneed, J. Lewis Maynard, and Robert C. Brasted. D. Van Nos- trand Co., Inc., New York 3, N.Y., 1953. 232 pages, 6 X 9 inches, illus- trated and indexed. Price $5.00. First of eleven volumes on in- organic compounds. The editors are stressing extensiveness of cover- age in lieu of fullness of treatment. This volume is divided into three sections, one being written by each, W. N. Lipscomb, P. R. O'Connor, and G. T. Seabord, respectively. The entire volume covers various phases of atomic and nuclear chem- istry with 61 pages devoted to the Actinide series, an arbitrary classi- fication. One can question O'Connor's list- ing of the six fundamental particles in which the photon is not included. The editors' preface gives a some- what confused intent. This re- viewer finds the first volume to be well done and more coherent than expected. It is doubtful if the series are intended to, or can, be of the same stature as Gmelin's well- known treatise. But there is a need for a new approach to many old inorganic discussions, particularly in the light of the status of inorganic chemistry since the explosion of the first atomic bomb. The volumes appear to be fairly priced. This makes it more interest- ing to start the complete set.--M. G. DENAVARRE. COMPREHENSIVE INORGANIC CHEM- ISTRY, Vol. II, edited by M. Cannon Sneed, J. Lewis Maynard, and Robert C. Brasted. D. van Nos- trand Co., Inc., New York 3, N.Y., 1954. 248 pages, 6 X 9 inches, illus- trated and indexed. Price $5.00. This second of the l 1-volume series begins to follow the pace for the entire set. It was written by
