MACMILLAN & CO.'S NEW SCIENTIFIC BOOKS. BY J. L. KIPLING C.I.E. Now Ready, 8vo, 21s. BEAST AND MAN IN INDIA. A POPULAR SKETCH OF INDIAN ANIMALS IN THEIR RELATION WITH THE PEOPLE. By JOHN LOCKWOOD KIPLING, C.I.E. With many Illustrations by the Author. TIMES:-"Mr. Kipling's book is that of a skilled artist as well as a keen observer. He goes through the whole of the fauna of India in its relation to man, illustrating it copiously and effectively with his own and other pencils, including those of more than one native artist." PALL MALL GAZETTE:-"A volume of animal lore, and a right excellent one it will be pronounced by all those interested in folk and animal lore. Mr. Kipling has managed to compress into 400 pages an unusually large amount of really interesting information. He is scientific without being pedantic, and chatty without ever being garrulous. The general public will welcome the book chiefly on account of its more amusing and cheerfully instructive contents, and those who expect much will, for the nonce, not be disappointed. The book is full of good stories and of charming illustrations." ST. JAMES'S GAZETTE:-"A book which will give English readers a truer conception of the character of the natives than a whole library full of standard works. It was a happy idea to define the progress and limits of civilization in India by describing the relations between man and beast. . . . Mr. Kipling is equally clever with pen and pencil. The result is a very charming volume, which is at once entertaining and instructive. Of the admirable drawings.. we cannot speak too highly. Of the book itself, we can only repeat that it is one of the best about India we have seen for a long time." BY W. J. MCCLELLAND, M.A. A TREATISE ON THE GEOMETRY OF THE CIRCLE, AND SOME EXTENSIONS TO CONIC SECTIONS BY THE METHOD OF RECIPROCATION. With numerous Examples by WILLIAM J. MCCLELLAND, M.A., Principal of Santry School, Dublin. PROGRESSIVE Now Ready, Globe 8vo, 2s. 6d. MATHEMATICAL EXERCISES FOR HOME WORK. First Series. By A. T. RICHARDSON, M.A., Senior Mathematical Master at the Isle of Wight College. 8vo, Price advanced to 15s. net. THE THEORY OF LIGHT. By THOMAS PRESTON, M.A., Trinity College, Dublin. SPEAKER:—“It is the very model of what an advanced text-book ought to be, and the mathematical proofs are given with a crispness and simplicity which furnish a continual treat." SPECTATOR:-"A decidedly clear, straightforward, and exact treatise.' SATURDAY REVIEW:-"A remarkably clear and concise exposition of the undulatory theory as it stands at the present time." SECOND PART OF LOEWY'S COURSE OF NATURAL SCIENCE. Now Ready, Globe 8vo, Cloth, 2s. 6d. GRADUATED COURSE OF NATURAL SCIENCE, EXPERIMENTAL AND THEORETICAL, for Schools and Colleges. Part II. Second and Third Years' Course for the Intermediate Classes of Colleges and Technical Schools. By BENJAMIN LOEWY, F. R. A. S., &c. With Sixty Diagrams. IRON:-" Well adapted to the requirements of the growing number of middle-class and technical schools in which a general course of experimental and theoretical work is desired. He has throughout aimed at rendering the experiments feasible with a very limited apparatus, and inexpensive materials and appliances." BY WILLIAM SMART, M.A. Now Published, Crown 8vo, Cloth, 35. net. AN INTRODUCTION TO THE THEORY OF VALUE, on the lines of THE POSITIVE THEORY OF CAPITAL. By EUGEN V. BOHM BAWERK, TIMES:-"Mr. Smart has done his work excellently. His preface, analytical digest, and the actual translation are all admirable. We have to thank him for rendering accessible to English students a treatise which is certainly well worth attention as a specimen of contemporary Continental thought, and which, although its central theory is based, as the author frankly avows, upon certain ideas of Jevons, has carried those ideas further and given them a special application." BY DR. THORNE THORNE, F.R.S. DIPHTHERIA: ITS NATURAL HISTORY AND PREVENTION. Being the Milroy Lectures delivered before the Royal College of Physicians of London, 1891, by R. THORNE THORNE, M.B. Lond., F.R.C.P., F.R.S., Assistant Medical Officer to Her Majesty's Local Government Board. TIMES:-"To non-professional readers, perhaps the most important part of Dr. Thorne's work is that in which he deals statistically and etiologically with the serious increase in diphtheria in this country, attributable to the increasing aggregation of children in elementary schools.. Dr. Thorne's suggestive treatment of this subject may be commended to the serious attention of all who are concerned with elementary education.' WHITTAKER'S NEW BOOKS. CAMBRIDGE UNIVERSITY PRESS.
