Emphasis in the preface on physicol meanurements leads one to wonder what other kind of measurement is possible. This new volume seems to be s worthy addition to the treatise. Again the set is recommended for a general persppctive of the hasis and spplicnhility of the tpchniques covered.

TRACE ELEMENTS IN HUMAN AND ANIMAL NUTRITION
E. I. Underwood, Institute of Agriculture, University of Western Australia. Academic Press, Inc., New York, 1956. 430 pp. 29 figs. 47 tables. 1 6 X 23.5 cm. $9.50 THIS book was written by an out. standing authority and worker in the field of trace element research and is the first hook to be devoted entirely to the significance of trace elements in the nutrition of
man and domestic animals. The author has devoted the first chapter to an intr* duction of the subject and an entire chapter t o each of the following trace elements: iron, copper, molybdenum, cohalt, nickel, zinc, manganese, iodine, fluorine, and selenium. Chapter 12 covers eight elements: aluminum, arsenic, barium, boron, bromine, silicon, strontium, and vanadium. The last chapter is s. summary of soil-plant-animal interrelationships. In each of the ten chapters devoted to a single element the author has considered the nutritionally important aspects as well as the toxicity of each of the ten elements. The author has included a historical treatment of the work which has been done on each of the elemunts so that the student may Lymalise the stepbystep development of knowledge regarding the nutritional implication of these trace elements. He is also s~tceessiul in his efforts to review the important original articles and has made reference to many of the reviews whirh have been written on each of the elements whieh the book is concerned. "Traoe Elements in Human and Animal Nutrition" ha8 been written especially lor those interested in the nubrition field, hut it should also he a welcome addition to the reference shelf of all scientists interested in the biological significance of theseelernents.

"TXE present hook comprises tho proceedings of a conference on biological waste treabmcnt, held a t Manhattan College in April, 19.55, a t whieh Limo leaders in this field delivered a series of papers reviewing advances and presenting new information!' Thirty-three papers are presented and are arranged into four parts: Part I , Theory and Mechanism of Biological Waste Treatment (10 papers), Part 11, Aeration-Theory and Design (10 papers), Part 111, Sewage Treatment (7 papem), and Part IV, Industrial Waste Treatment (6 papers). Each part is roncluded with a lengthy list of references. A t tho end of Part IV appear an author index and a subject index. As might he expected there is not a clear continuity between successive papers, and each must he considered as a separate ent,ity. A more adequate subject index would have helped to alleviate this lack of continuity. The papers artre written in a scholarly iashion. Photographs, tables. and figures are very legible. The brief amount oi chemistry included is col.wet (Continued on page A.?g4)

and pnsily understood. There are many formulae and equations, including t,he one of some raleulus. This book should be of value to persons concerned with problems of waste treatment in that i t presents under one cover material otherwise presant only in vnrioua ,ia,n-nnla.

CHEI~ICAL hi~tol.i&n~ will wekome this eamprehmsive, wcll documented tt.eat.ment of an important phase in educational and economic history. The entire rotme of British rhemianl history might have been greatly altered if the government and the Anglican Chnrrh had not so long neglceted or even opposed thorough training in t,he sciences. England x a s getting along without such programs, so why rhange? The function of the instit+ tiom of higher learning was t o turn out clergymen: t o educatp t,he great mass of the ~ x q h might lend them t o efforts to
~ . i f iabove ~ thrir n ~ t u r s l station. Thia attitude, which was not s h a l d hy the Scotch, led to n. sitnation in which young men bent on securing a scientific education were forced t o go ahroad. The German rulers had recognized the importance of the seicnco cnrrierrla, and they furthered the growth of the science faculties for both military and economic reasons. Prince Alhert, a native of Germany, had received a broad education; he was fully aware of the necessity of the training in sciences such as u.ns avai1;thle in Liehig's labomtory s t Giessen. Albert was rhicfly responsible for the founding of The Royal College of Chemistry but his early death was soon followed by the closing of this promising srhool, whose most famous student was the discoverer of mauve, o. feat whose ccntcnary w s celebrated in 1956. The xut,hor has traced the German influence particularly in hiology and chemistry. An extremely valuable feature is the extensive chart in which 325 scientists active in Britain during this period s1.e nnalyaed as t o nationality, place of training, and field of artivity. These valuable data reveal the tremendous contribution of German 8rhool~t o British science in the first three qnarters of the nineteenth century. This is an intermtino, ~rholarlyhook and n r e d rontril,ution to an important chapter in t h r hist,ory of chemical eduration. RALPII E. OESPER u ~ l v l n s l ~OF r C,AC,NS.,TL

MODERN METHODS OF MICROSCOPY Edited by A. E. 1. Vickers, Thermal Syndicate Ltd., Wallsend-on-Tyne. Butterworths Scientific Publications, London, 1956. 114 pp. Many figs. and tables, 1 8 X 24.5 cm. Hard paper cover. $3.50. THIS small volume comprises a series of articles on modern microscopy reprinted from Research. These articles cover recent developments in electron, reflecting, fluorescence, metallnrgicnl, phanc, interference, flying spat and X-ray microscopy. Also included are rhapte1.8 on numerical values and quantitative determinations and surface micra-interferomotry. While much mare extensive coverage of some of tho individual areas auch as electron, phase, metallurgical, and polnrining microscopy is available, and more extensive literature review eovwage l i k e wise is available in reviews such as thosf appearing from time t o time in Analytical Chemistry, no single comparable hook is svailable which treats all of the modern methods of microscopy. Most of the articles artre in the form of reviews, well referenced, covering not only rerent, d ~ v o l o ~ r n e n t sin instrumentation and application but also basin theory, historical and early developments. I t is a n excellent book for its siee and moderate priw. CHARLES M4RESH Crra*Ml" COMPINI ROUNDBROOX, N e r ~JBRBEI
