EVAPORATING, CONDENSING AND COOLING APPARATUS. BY 

 F Hausbrand. Translated from the second, revised German edition 

 by A. C. Wright, M.A.. B.Sc. Second English Edition. Revised. 

 Scott, Greenwood & Son, London, 1916. American distributers, D. Van

THIS authoritative work by the chief engineer of C. Heckmann, 

 Berlin, and author of "Drying by Means of Air and Steam," 

 is of exceptional value to engineers because of its table of 

 coefficients giving positive answrers to all questions ordinarily 

 arising. Certain arithmetical and printer's errors of the former 

 edition have been corrected and conversion diagrams have been 

 appended by means of which the quantities in metric units may be 

 readily converted into British units. 



The treatise takes up transmission of heat, apparatus for 

 heating with direct fire, injection of saturated steam, super- 

 heated steam, evaporation by hot liquids, transference of heat 

 in general, evaporation in vacuum, evaporators of different types, 

 diameter of pipes for steam, alcohol vapor, air and water, losses 

 of heat by radiation, condensers, heating and cooling of liquids, 

 air pumps, etc. 



CHEMICAL DISCOVERY AND INVENTION IN THE TWENTIETH

In this volume one of the most distinguished chemists of 

 Great Britain and professor emeritus of chemistry in the Im- 

 perial College of Science and Technology, presents a thrilling 

 account of the momentous conquests of matter by human 

 knowledge during the past quarter century. The work is divided 

 into four parts, the first being devoted to laboratories and lab- 

 oratory apparatus for general teaching and special purposes. 

 The second part deals with modern discoveries and theories, 

 such as the disintegration and transmutation of elements, electrol- 

 ysis, catalysis, architecture of molecules, etc. The third part 

 treats modern applications of chemistry, including water and its 

 purification, petrol, coal tar, dyes, essential oils, vegetable fiber 

 and products from cellulose, explosives, fixation of atmospheric 

 nitrogen, and rubber. The fourth part takes up progress in 

 organic chemistry, particularly sugar, proteins, natural colors 

 and enzymes. 



The chapter on rubber reviews the principal sorts and sources 

 with statistical production and trade data in quantity and value, 

 both wild and cultivated. Plantation practice is sketched briefly ; 

 also the composition and constitution of rubber, rubber sub- 

 stitutes, the process of vulcanization, reclaiming, and concludes 

 with a history of synthetic rubber. It is pointed out that the 

 by-product, acetone, may become so profitable as to reduce the 

 cost of butadiene rubber considerably, and so assist the synthetic 

 in competition with the natural rubber. However, it is stated 

 that the tnany difficulties yet to be overcome are such that 

 rubber planters need entertain no alarm, particularly in view 

 of the many new uses to which increased production might 

 be put. especially if obtainable at reduced cost. 



THE WORLD'S COTTON CROPS. BY JOHN A. TODD, B.L. A. & 

 C. Black, Limited, London, England. The Macmillan Co., New York 

 City. [8vp, cloth, 460 pages. Price $4.25.] 



.A.t the present time, when the cotton trade stands in a critical 

 condition as regards its raw material, and when so much pioneer 

 development work is being done in connection with cotton grow- 

 ing, this volume will be especially welcome. It gives an account 

 of the sources and varieties of raw cotton in non-technical lang- 

 uage for the average grower and consumer, telling the former of 

 the final destination and use of his crop and his rivals in other 

 countries, and informing the latter of the conditions under which 

 tiis raw material is produced and how to estimate future pros- 



pects and determine the possibilities of new sources of supply. 

 The author spent five years in Egypt and visited practically the 

 whole of the American cotton belt and was born and brought 

 up in close touch with the west of Scotland cotton industry, so 

 that he has had exceptional opportunities to study his subject. 

 Aside from general chapters on the cotton plant, geographical 

 distribution of cotton, the uses of cotton and cottonseed, and 

 the effects of the war, special chapters are devoted to the dif- 

 ferent cotton producing countries, including India, China, Japan 

 and Indo-China ; United States, Mexico, etc. ; the price of Amer- 

 ican cotton ; British West Africa ; British East and Southeast 

 Africa; other African colonies; South America; hand-staple 

 .•\mcrican Upland; Egypt; Anglo-Egyptian Soudan; Sea Island 

 cotton ; Oceania, etc. Many excellent half-tones, maps, diagrams 

 and a statistical, appendix illustrate and supplement the text. 



The disproportionate space allotted to Egypt is fully justified 

 on the ground that Egypt is the world's chief example of cotton 

 growing under irrigation, which, in the writer's opinion, is 

 showing a tendency to become the prevailing method of cotton 

 growing, which is now responsible for at least half of the world's 

 crops, other than American, in Egypt, India, Russia, many parts 

 of Africa, Peru, Arizona and California. 



THE LAW APPLIED TO MOTOR VEHICLES. BY CHARLES J. BAB- 

 bitt; Second Edition by Arthur W. Blakemore, West Publishing Co., 

 St. Paul, Minnesota. [Large Svo, 1,262 pages, buckram binding. 

 Price, $7.50.J 



The universality of motor vehicles, for pleasure or business, 

 makes the questions of law regarding them, the rights and 

 privileges of their owners, their liability in cases of acci 

 dent, and the many knotty legal points which have been decided 

 upon matters of special interest. This volume, bound in the 

 modern law library style, contains, under nearly 1,800 heads, the 

 epitome of thousands of judicial decisions, so arranged that 

 the special circumstances of each case are set down as the rea- 

 sons for such decisions. An appendix gives the laws regarding 

 right of way, laws of the road, street-traffic regulations, head- 

 light laws, speed limitations, registration, fees, etc., of all the 

 states. The first edition was by the late C. J. Babbitt. This 

 second edition was prepared by Arthur W. Blakemore, of the 

 Massachusetts bar, who has added many decisions which have 

 been handed down in the interim. The work shows thorough, 

 careful and conscientious study in its preparation.
