BEYOND THE FLYLEAF Jecond Report on Viscosity and PlasJ ticity. Committee for the Study of Viscosity of the Academy of Sciences in Amsterdam. VII -+• 276 pages. (In English.) Nordemann Publishing Co., Inc., 215 Fourth Ave., New York, Ν. Υ., 1938. Price, $7.50. THIS second volume on viscosity and plas ticity is in accordance with the original plan. The Preface carries the name, which is well known in America, of H. R. Kruyt, president of the committee. There are six chapters: I. Recent Inves tigations, by J. M. Burgers; II. Viscosity and Chemical Properties and Physical Constitution, by F. M. Jaeger; III. Motion of Small Elongated Particles Sus pended in a Viscous Liquid, by J. M. Burgers: IV. The Yield Value, by R. Houwink; V. Recent Plastometers, by C. J. van Nieuwenburg; and VI. Tech nical Capillary Viscometers, by R. N. J. Saal. There is no question as to the com petence of the committee and it is worthy of note that although each chapter is the work of one man, all of the contributions have been the subject of discussion by the full committee, selected to represent vari ous fields. This volume is not intended to be a complete survey of the work in tins field. It is a critical discussion of various phases of the progress of the science with the authority that this committee gives. That is of very great value. The volume has a good index. It is to be hoped that the committee will continue its labors bringing out other volumes dealing with subjects yet un treated, such as viscosity and reaction ve locity, the viscosity of electrolytes, the significance in physiology of the viscosity of the body fluids. The vast significance of flow in metals or of the resistance to flow, which is the same thing, has thus far been dealt with very inadequately. The work of JofTé, Elam, Hough et al. suggests that the flow of metals will not always be simply "the imperfection of elasticity." EUGENE C. BINGHAM

THIS book, prepared primarily as "A Manual for Petroleum Technologists, Students, Engineers, Oil Salesmen, etc." is an outstanding compilation of the prin ciples and practice of lubrication and should be of interest to all producers and users of lubricants. The subjects covered may be divided into four groups: friction, and the de sign and lubrication of bearings ; chemistry, sources and manufacture of lubricants; chemical, physical, and mechanical test ing; and industrial applications and care of lubricants. The properties of the newer bearing materials used in automotive practice and the effect of fatigue on bearing life are omitted, but designers and engineers will find considerable valuable fundamental information in the chapter on The Design and Lubrication of Bearings.
The chapters on Source of Lubricants, The Chemistry of Lubricants, and In dustrial Lubrication Practice "summarize concisely the salient features'' of the chemistry, methods of refining, and ap plication of petroleum and animal and vegetable lubricants. The manufacture ana application of extreme-pressure lubri cants, cutting oils, and greases are also included. The oxidation of lubricating oils, especially engine crankcase oil, and the use of inhibitors or antioxidants have been dismissed by the authors too briefly in view of the commercial importance of these subjects. The chapters on Specific Gravity and Viscosity, and Chemical and Physical Testing give the principles involved in the conventional and commonly applied laboratory tests on lubricating oils and discuss the significance of these tests. The analyst is referred to the official method for complete details. An Ap pendix (22 pages) contains useful physical data and conversion tables. The mechanism of lubrication and the use of laboratory testing machines for determining coefficient of friction and loadcarrying ability of lubricants are treated under Mechanical Friction Testing Ma chines. An excellent list of references, particu larly of interest to the research worker, is given at the end of each chapter. It has been definitely established by a number of investigators that pour point determines only the ability of the lubri cating system to deliver lubricant to the bearing surfaces and that viscosity, at the starting temperature, alone deter mines the torque requirements in start ing an automobile engine. It is therefore surprising to read (page 254) that "the significance of the cold test has been shown to determine whether the oils will permit easy starting in cold weather." American automotive engineers will not agree with the authors (page 258) that, as a result of excessive dilution, "the sumps of motor-car engines operating in the United States need to be emptied every 500 miles, whereas in this country (England) every 2000 miles will suffice/' Despite these criticisms, this book con tains a wealth of information on lubri cants and lubrication and deserves a prominent place among the too few au thoritative works on this important in dustrial subject.

2nd ed. 628 pages. John Wiley & Sons, Inc., 440 Fourth Ave., New York, Ν. Υ., 1938. Price, $9.50. THE Preface to the second edition of this book states: "Some of the material in the first edition is now out of date and it has been considered necessary to make certain alterations and additions." As the book is voluminous, an attempt to abstract the complete work is out of the question and reviewer's comments will be confined to brief discussions of the most important changes. As a matter of fact, so many additions and alterations have been made in the second edition that it would be impractical even to men tion all of them. Many alterations, which include rather extensive rearrangements of various sub ject topics within the chapters and also combination of certain chapters, make for improvement in sequence. For these rea sons alone the second edition is definitely increased in value for use as a current reference or as a text and guide for those who are undertaking a study of the sub ject matter for the first time. The out standing new contribution is the chapter entitled "Pyrolysis and Polymerization Process for the Production of Refinery and Natural Gases." Developments in this field, together with recently created demands for high octane number blending agents, have made polymerization and hydrogénation processes loom importantly in the petroleum industry. The authors are to be commended on their comprehensive historical review and the thorough description of processes and principles involved. That this field is rich in potentialities is evidenced in no small way by extensive current investigations and numerous published papers. For this reason the reviewer feels that the authors have justly devoted a comparatively large section to this subject and its allied problems. A number of improvements and additions appear in the chapter on cracking process, etc., from the point of view of practice within the United States alone. However, this chapter does not appear to be quite as comprehensive as might be desired and it will undoubtedly be found of greater interest to readers from other countries. These comments are made in spite of the fact that the authors have done an admirable job of discussing cracking processes in general. The chapters on Natural Gasoline Recovery and Finishing of Motor Fuels have been similarly improved, although again they are principally representative of pro-

cedures foreign to the United States. The chapter on shipping and storage prob lems, insurance matters, etc., might either be deleted or at least relegated to the po sition of an appendix, as it does not appear to be on a par with the thoroughness em ployed in the preparation of the other chapters on actual manufacturing prob lems. The chapters devoted to alcohol and benzol motor fuels constitute detailed considerations which might be regarded disproportionate to their current use, particularly in t h e United States. It is recognized that a fairly complete treat ment of these fuels may be justified in view of their more extensive use in other countries. The most recent information on this subject, which is partly substanti ated by data given in the chapter on al cohol fuels, suggests, however, that as time goes on substitute fuels may be rele gated to somewhat less important posi tions. Also it would seem that the chapter on benzol would be more logically located with that on alcohol fuels in the latter part of the book. In conclusion, it should be commented that this probably represents the most complete and carefully prepared book of its kind available. It is greatly to be hoped that the authors will continue their commendable policy of revising the book at as frequent intervals as possible for the purpose of keeping it well abreast of a rapidly changing industry. As was suggested in the review of the first edi tion, it might be found desirable to issue supplements to certain chapters, particu larly those on cracking, polymerization, etc., in which developments are currently taking place at very rapid rates.

ritish Chemical Industry. Its Rise ΒMorgan and Development. Sir Gilbert T. and David Doig Pratt. 372 pages. 56 illustrations. Longmans, Green and Co., New York, Ν. Υ., 1938. Price, $6.25. T H I S book is t h e outcome of a series of public lectures delivered at the University College of Wales. It is a summary of the beginning and rise, to its present state, of British chemical industry. At times the historical facts are brief and not revealed with as much detail as might be desired, but such a treatment would have extended the present book considerably and the admirable descriptions of present-day practice would have suffered. This volume should be interesting not only to those who received their chemical training in England, but to the American engineer who wishes to make a compari son of American and British methods. Throughout one feels the constant desire of England t o obtain a more self-sufficient chemical industry and in view of the pres ent European situation this study is timely. This desire is quite apparent when the authors discuss the sulfuric acid industry, for which England must import its raw materials. It is with some relief that they note that the alkali industries are no longer dependent upon sulfuric acid and that t h e fixation of atmospheric nitrogen has eliminated its necessity in the manufacture of fertilizers and explo sives. Subjects covered are salt; sulfur, sand, clay, and limestone; industrial gases; se lected metallurgical processes; borax and Îmosphate; paints and pigments; oils, ats, and waxes; cellulose; coal; oil shale and petroleum; explosives; dyestuffs and intermediates; plastics and rubber; industrial solvents; and fine chemicals.

T H I S book presents concise and systematic descriptions along with unusually complete literature references of the up-todate materials which are used for linseed oil substitutions. Although not chemically rigorous in its treatment, the author handles the subject in such a manner that it becomes of interest particularly to the consumer of these materials. A detailed description is given of the industrially important drying oils, and mention is made of the lesser known glycerides, which, however, have equal scientific interest. The fish oils receive due consideration, as do the drying mineral oils, because of their increasing interest. Concise treatment is given to the synthetic resins, with more detail, however, on the nitro and acetyl cellulose as well as vinyl compounds. The volume is recommended to the consumers of these materials and as an introduction for students who intend to make a more comprehensive study of the substitution products. H. J. ASBECK
aschenbuch fur die Lebensmittelchemie. A. Thiel and R. Strohecker, Twith cooperation of H. Patzsch. 172 pages, Preface and Index. Walter de Gruyter & Co., Berlin, 1938. T H E authors state in the Preface that the book can be regarded as a supplement to t4 Logarithmische Rechentafeln," by J. W. Kuester and A. Thiel, which it resembles to a great extent. The Preface, by A. Thiel, is followed by an index, dividing the book into 66 tables and giving the subject treated in each table. The introduction calls attention to one radical innovation. After taking up the definitions of density and specific gravity, it is stated: "The term 'specific gravity' does not occur in this book." Specific gravity is replaced by ratio of weights (Gewichtsverhaltnis) expressed by the formula 7L|0/|ot where L stands for air (Luft) and the upper t° represents the weight of the substance and the temperature at which it was taken, the lower r the weight of the same volume of water and its temperature. Another divergence from general American practice is that the amount of copper reduced from Fehling's solution in gravimetric sugar determinations is not given in terms of Cu*0, but as CuO. Therefore the cuprous oxide will have t o be oxidized to cupric oxide before weighing, or a corresponding calculation made before the value for sugar can be read from the table. The 66 tables are divided into seven groups. The observation data are given in the tables in red print, while the results to be found are printed in black. Tables 11, 14, 25, 48, 49, 50, 54, and 66, which give general information, are printed in black only. The titles of the groups are: Milk; Water and Sewage; Sugar and Extract (or Water); Wine; Fats; General Analysis. The book has been written specifically for German conditions and frequent reference is made to (German publications and even to official German regulations (Tables 28, 29, and 34 to 38). A typographical error has occurred on page 136, where the number of the table should read 43, instead of 34. A four-figure table of logarithms is attached to the book in a back cover pocket.
The information given appears to be correct and up to date. The tables are made easily available through the thumbcut general index, in addition to the detailed index of the tables. The small size of the book facilitates its use. The print throughout is very clear and easily legible. G. D . THEVENOT

THIS book, by a distinguished French en gineer, deals with the cleaning, drying, briquetting, and crushing of coal. It is a well-considered, descriptive appraisal of present-day practice in the coal prepara tion plants of Europe. Primary consid eration is given to plant operation and the problems encountered therein, although rinciples of processes are concisely stated, 'ypical results obtained in plants employ ing the various processes described are given. The book is illustrated with 111 figures, principally line drawings. Wet cleaning methods, as practiced with modern jigs and rheolaveurs, are critically discussed in 7 chapters comprising 75 pages. Those processes employing or simulating float-and-sink separation by means of dense liquid media are care fully treated in 3 chapters covering 46 pages. Especially interesting are the re sults obtained at plants employing the deVooys process, wherein clay and barium sulfate are used to give a high density medium. Pneumatic processes are dis cussed in 6 chapters of 6(5 pages, which give details of plants employing the Birtley. Revelart-Berry, Meunier, Sulary, and P. I. C. pneumatic cleaning processes, the latter recently introduced in France. Three chapters of 50 pages give the results obtained a t plants employing froth flota tion for cleaning fine sizes. The Kleinbentink process used at the Dutch State Mines, Lirobourg, and the LeChatelierPic as employed in France, as well as the familiar minerals separation process, are discussed with full descriptions and Une drawings of the apparatus and rather com plete information on the character and quality of the products resulting from this method of treatment. Briquetting processes are concisely cov ered in 2 chapters of 40 pages. Two chap ters, comprising 18 pages, discuss crushing problems, one of which deals with the crushing and retreatment of middlings. Centrifugal and heat drying are treated briefly in 3 chapters of 12 pages. A welcome addition to each chapter is a statement of conclusions and, in addition, the entire book has a concise summary at the end. A departure from other books on the same subject is a chapter describing two processes used for dehydrating lig nite without at the same time causing it to degrade excessively in size. These are the Ruzicke-Simek process employing superheated steam, as applied in Bohemia, and the Filiti process employing heated

As THE title indicates this book has to do with the physico-chemical and eco nomic considerations of the chemical operations. It is divided into three parts, the first on the maximum yields as determined on the basis of chemical equilibria, the second on technical re action velocities, and the third on the costs of chemical operations. The theory and calculations of chemical equilibria at constant temperature for homogeneous and heterogeneous systems, the thermo dynamics and thermodynamic calcula tions of heat of reactions, molecular heat, and constants and formulas for accurate calculations of equilibria are given. A number of sample calculations are also presented. The second division of the book has to do with technical reaction velocities for isothermal and homogeneous systems, the fundamentals, experimental methods, activation and reaction temperatures of mono and polymolecular reactions. The subject of parallel reactions is also in cluded. Methods of reducing the time of reaction without decreasing the yields by catalysis are discussed at great length. Of particular interest is the section on gasification of solid fuels, the solution of metals, reactions in which porous products result and those that follow or are de pendent on formation of thick films. In addition reactions between solid phases and reactions between small particles and fine crystals are well illustrated. Another section has to do with the eflfect of diffusion, heat transfer, concentrations, etc., on the yield in technico-chemical reactions. The last chapter deals with economics of chemical operations with special con sideration of materials, energy, personnel and capital costs, depreciation, main tenance, and general costs. Kxamples of calculating costs are indicated. The author of this chapter discusses the difficulties and uncertainties in calculat ing cost and designing equipment from data obtained on an experimental labora tory basis though he suggests some value in using the method of similarity. The whole book is well and clearly written and is very comprehensive. I'nits and symbols differ considerably from American practice which makes for some difficulty in its use. It is a complete source of physical chemistry of chemical ojM?rations available to the chemical engineer.

Solution of Electrolytic Manganese Problem r
|^HE successful solution of the electroI lytic manganese problem, which pro vides a method for the recovery of highpurity metallic manganese from low-grade ores, devised by the Bureau of Mines, I'nited States Department of the Interior, is recorded in a progress report recently published. The process for the electrolytic produc tion of manganese from its ores as it now stands, and which is regarded as a com mercially feasible one, is much different from that described in previous publica tion*. It consists essentially of several ste|>s, which may be briefly outlined as follows: Roasting the ore in a reducing atmosphere to convert the higher oxides of manganese to maiiKune.se oxide. This is «lone in an exter nally heated rot at in κ kiln similar to that used in the Oaroti-C'levenger process. The ore must IK» cooled in a reducing atmosphere. The roastc»«l ore is then leached with the spent electrolyte from the electrolytic cells. This spent electrolyte contains alxmt 2.5 to 3 per cent of sulfuric acid. This insoluble is removed by settlitmand filtration. The leach li«nJr is then treated for the re moval of impurities. Iron ami arsenic are removed by the addition of manganese di oxide, which occurs as an anode product «lur ing electrolysis and agitation with air. The precipitated ferric hydroxide* with the oc cluded arsenic are removed by filt rat ion. The solution is then treated for cobalt and nickel, which have lieen found to lie highly iletrimcntal to the electrolysis of manganese. After filtration, the solution passes to the reservoir feeding the ele«*trolytic cell. The cell has lead anodes and stainless-steel start ing cathodes separated by canvas dia phragms. It i* fed continuously, and the spent anolyte is run off ami filtered to remove some manganese dioxide that is forme«l at the anode. The s|M»nt anolyte returns to the leaching circuit. The current density is approximately 20 amperes per square foot. The energy con sumed averages from 3.2 to 3.7 kilowatthours per pound of metal.
541 Analysis of the metal showed 99.63 per cent manganese. The principal impurity was sulfur from the electrolyte. Other impurities were in the third and fourth decimal places. Several hundred pounds of this metal have been produced for ex perimental purposes.

It is well illus trated, has many tables of information, maps that are informative, flow sheets that arc valuable; in fact, all the earmarks of a well-done publication. The commission estimates that electroprocess operations consume more than 0.1 as much electrical energy as the total amount generated for public use in the United States. Past requirements are est imat ed at 13,324,000,000 kilowat t-hours annually and within five years, based on trends and increasing demands in these industries, it is estimated that require ments will increase approximately onethird to 17,781,000,000 kilowatt-hours.
