THE SCIENTIFIC MONTHLY-ADVERTISEMENTS

Hertha Ayrton, 1854-1923: A Memoir By EVELYN SHARP As a girl Hertha Ayrton knew George Eliot, William De Morgan, and William Morris. Later, she was the friend of educational pioneers like Madame Belloc and Barbara Bodiehon. Her laboratory researches led to important discoveries in electricity and she carried out fruitful re- searches in the effect of tide waters on shorelinies. She was elected the only woman member of the Institution of Electrical Engineers and won the high regard of scientists of many countries, including the brilliant Mme. Curie. "Hertha Ayrton appears a strong and fascinatinig personality in this attractive memoir. . . . If the account of her public life is absorbing, that of her private interests is no less charming.'-The Times Literary Supplement.

Illustrated, $5.50

A Study of the Oceans By JAMES JOHNSTONE In this volume the author first deals in a simple and lucid manner with the various theories as to the origin of the earth and the formation of the oceans in remote geological ages. He then treats of the classical geography of the ocean and from ancient maps shows how the original conception that the habitable world comprised only the lands around the Mediterranean was gradually abandoned. The various voyages undertaken to discover the extent of the oceans and the existence of other lands are next described, and finally chapters are devoted to the eircumpolar regions and to the Atlantic, Pacific and Indian Oceans.

Illustrated, $3.75

Sunshine and Open Air: Their Influence on Health, with Special Reference to the Alpine Climate By LEONARD HILL "There may be some room for controversy over the extent to which environment determines human characteristics, but there can be none on the score of its relation to health. And the new book, written by experts in this field, one of them a physiologist, the other a physician, drives home the lesson in many richly freighted chapters well within the comprehension of the general reader. " -Boston Transcript.

$3.75

The English Brass and Copper Industries By HENRY HAMILTON "All who have more than a 'living' interest in the copper and brass industry will procure and read this book, not only as history, but for its culture value. . . . This is a dry statistical subject made historical with a charm of style that evinces much skill and literary judgment."-Brass World.

$6.oo

On the Eaves of the World By REGINALD FARRER New edition "The expedition of which these two volumes tell the first half of the tale was definitely planned (though long dreamed of) in 1913, and got going on February 7, 1914. Its object was to ex- plore thoroughly, in the interests of horticulture and forestry, the whole of the Kansu-Tibet Border, from South to North." -From the Foreword to the book.

AMERICAN MEN OF SCIENCE A BIOGRAPHICAL DIRECTORY

The third edition of the Biographical Directory of AMERICAN MEN OF SCI- ENCE was published in June, 1921, and contains the records of more than 9,500 living men of science, as compared with about 4,000 in the first edition and about 5,500 in the second edition. No single book of reference can cover the whole of North America and all lines of activity; it therefore became necessary to prepare special works. This volume, devoted to the men of science, sets standards in its treatment of a group on which the material prosperity and intellectual leadership of the country depend. This directory should be in the hands of all those who are directly or indirectly interested in scientific work. Price: Ten Dollars, net, postage paid.

THE SCIENTIFIC MONTHLY-ADVERTISEMENTS in

VOLUME ONE Of Jerome Alexander's Great Compilation on

COLLOID CHEMISTRY Theoretical and Applied

JEROME ALEXANDER began his compilation of this great book in the fall of I922. Realizing that no one man or limited group of men couild write a satisfactory book

on the subject, he set out to obtain the cooperation of competent men in all countries. This book therefore is international so far as the source of its material is concerned. The broad subject of Colloid Chemistry is to be treated in several volumes and more than I75 contributors have promised papers. The present volume, No. i in the set, is devoted to the theoretical and applie-d phases of Colloid Chemistry.

SIXTY AUTHORS HAVE CONTRIBUTED TO VOLUME I This Volume is literally a Book of Books. The Authors are as follows:

This book, a revision of Plnht G&netics, has been written to meet an increasing need among botanical students. It is in- tended as a preparation for dealing with the general literature of plant genetics, and is well adapted to the needs of bot- any students, both beginning and ad- vanced.

By ROBERT A. MILLIKAN The Nobel Prize in Physics was

awarded to Professor Millikan on the basis of his researches into the subatomic world. He describes in The Electron his world-famed experiments; outlines the history of earlier electrical theories and earlier work on e from Franklin to H. A. Wilson; and discusses the two outstand- ing problems of modern physics: the structure of the atom and the nature of electro-magnetic radiation. His style here is semni-popular and designed to ap- peal not only to the physicist, but also to the reader of less technical training.

This is a completely revised edition which brings the discussion entirely up to date, including, for example, the Compton effect.

LIFE, MIND, AND SPIRIT By C. LLOYD MORGAN, University of Bristol

In this volume, the course of Gifford lectures delivered in 19,23 and supplementing those on Emergent Evolution, Professor Morgan argues that in the aseending hierarchy of stages of progress, regarded as manifestations of Divine Purpose, each higher stage is in turn super- natural to that which precedes it. He extends the hypothesis that Life is the synthetie unity of events in physical and physiological regard; Mind the different expression of like unity of events in mental regard; life and mind as the manifestations of God and Spirit, one and indivisible. A very important contribution to evolutionary discussion.

Manual of Injurious Insects By GLENN W. HERRICK, Cornell University

Treats every phase of the injurious insect, and gives the most approved methods of control. Contains simple synoptic tables, more than 100 maps of distribution, and 450 illustrations of insect pests and their work. "Herrick's 'Injurious Insects' is a most excellent work. It is clear and concise throughout, the author wastes no, time in approaching his subject and no words in dealing with it. For a book of its size the amount of material is surprising and nothing of importance appears to have beena omitted. Furthermore, for a text-book it is unusually up to date. "-Professor Raymond C.

A QUARTERLY REVIEW OF SCIENTIFIC THOUGHT, WORK AND AFFAIRS

Edited by COLONEL SIR RONALD ROSS K.C.B., K.C.M.G., F.R.S., N.L., D.Sc., LL.D.. M.D., F.R.C.S.

Assisted by D. ORSON WOOD, M. Sc., and J. BRONTE GATENBY, B. A., B. Sc.

SCIENCE PROGRESS owes its origin to an endeavor to found a scientific journal containing original papers and suimmaries of the present state of knowl- edge in all branches of science. The necessity for such a journal is to be found in the fact that, with the specialization which necessarily accompanies the mod- ern development of scientific thought and work, it is increasingly difficult for even the professional man of seience to keep in touch with the trend of thought and the progress achieved in subjects other than those in which his immediate interests lie. This difficulty is felt by teachers and students in colleges and schools, and by the general educated public interested in scientific questions. SCIENCE PROGRESS claims to have filled this want.

Published early in January, April, July, and October.
