and now that currents of different voltage and character are commercially available, the operation of electro-plating takes rank among the largeplant industries. The book is especially designed to assist foremen-platers, works-chemists and engineers. Much that does not bear on these objects has been omitted. Metals have been chosen that are of the most importance. The omission of silver has been due to a desire to economize space, but seems to be a matter of regret, as that metal is so largely used in the industry. The treatment of the whole subject is quite elaborate, theory as well as practice being extensively considered. An unusual and pleasing frankness is exemplified in the preface, the author inviting those that do not understand the statements to inquire of him by letter. This is undoubtedly a commendable attitude, but he may find the reaction to the suggestion more active than expected. The numerous photomicrographs of deposited films add greatly to the value and interest of the book. The metals treated are: Iron, nickel, zinc, lead, tin, chromium, copper. Special chapters are devoted to theory and practice. and the structure of electro-deposited metals. An original idea is a chapter on " Reading," which is a bibliography of important literature of the subject with comments on some of the items. The book throughout shows the originality of the author and the information given shows his extended familiarity with the subject. The progress of the industry is strikingly shown by comparing the book in hand with the small, thin volume issued by Napier in the middle of the last century. The early workers in this field would have been skeptical if told that in the future such metals as chromium and iron would be available as plating. It is true, indeed, that the author states that chromium plating has not been developed to a workshop procedure, but the step from laboratory success to industrial success is almost always accomplished, though " patient search and vigil long" may be required to attain the end. The book is a valuable contribution to the electro-plating industry, and it is to be hoped that a second edition will be soon demanded and the author will see his way clear to include the plating by silver, gold and platinum. HENRY LEFFMANN. TREATISE ON GENERAL AND INDUSTRIAL ORGANIC CHEMISTRY. By Dr. Ettore Molinari. Second English edition. Translated from the third enlarged and revised Italian edition, by Thomas H. Pope, B.Sc., F.I.C. Part II, vii-44I pages, .305 illustrations, 8vo. Philadelphia, P. Blakiston's Son and Company, I923. Price, $8 net. This volume is paged consec-utively with Part I of the organic chemistry, and contains the conclusion of the discussion of the aliphatic compounds with the cyclic series, proteins, glucosides and some other substances of uncertain or unknown composition. A section is given to coloring matters and also to textile fibres. The general nature and value of the work have been widely and favorably known since the first translation was published. The translator is well equipped for the work and has done it well. This being the continuation of a volume, there is no introductory matter or .preface, but the index, of course, covers both parts. The index is quite comprehensive. About three-quarters of a page are

devoted to the vitamins, probably quite enough considering the field to which the book is devoted and the limited knowledge as yet of these substances. A very large amount of information is presented in a compact and convenient form. The original text, having passed through the hands of a British chemist of experience and ability, has necessarily been somewhat better adapted to English-speaking workers, though it is evident that the author has a wide acquaintance with the subject and has produced a book of value and excellence. HENRY LEFFMANN. NATIONAL ADVISORY COMMITTEE FOR AERONAUTICS. Report No. 176, A Constant Pressure Bomb, by F. E. Stevens. 8 pages, illustrations, quarto. Washington, Government Printing Office, 1923. This report describes a new optical method of unusual simplicity and good accuracy suitable to the study of the kinetics of explosive gaseous reactions; it deals with a part of an investigation of the rates of explosive gaseous reactions being carried out at the Bureau of Standards at the request of and with the support of the National Advisory Committee for Aeronautics. The device is the complement of the spherical bomb of constant volume, and extends the applicability of the relationship, pv = n R T for gaseous equilibrium conditions, to the use of both factors p and v. The method substitutes for the mechanical complications of a manometer placed at some distance from the seat of reaction the possibility of allowing the radiant effects of the reaction to record themselves directly upon a sensitive film. It is possible the device may be of use in the study of the photo-electric effects of radiation. The method makes possible a greater precision in the measurement of normal flame velocities than was previously possible. An application of the method in the investigation of the relationship between flame velocity and the concentration of the reacting components, for the sims ple reaction 2C0 + 0., ~ 2C0,.., shows that the equation k = describes Cc2o Co~ the reaction. An approximate analysis shows that the increase of pressure and density ahead of the flame is negligible until the velocity of the flame approaches that of sound.
