YOUNG, Professor of Astronomy in the College of New Jersey. 8vo. viii + 551 pages. Half morocco. Illustrated with over 250 cuts and and diagrams, and supplemented with the necessary tables. Mailing price, $2.50; for introduction, $2.25. In amount, the work has been adjusted as closely as possible to the prevailing courses of study in our colleges. By omitting the fine print, a briefer course may be arranged. The eminence of Professor Young as an original investigator in astronomy, a lecturer and writer on the subject, and an instructor of college classes, and his scrupulous care in preparing this volume, led the publishers to present the work with the highest confidence; and this confidence has been fully justified by the event. More than one hundred colleges adopted the work within a year from its publication, and it is conceded to be the best astronomical text-book of its grade to be found anywhere. Edw. C. Pickering, Prof. of Astronomy, Harvard University: "I think this work the best of its kind, and admirably adapted to its purpose." S.P. Langley, Sec. Smithsonian Inst., Washington, D.C.: "I know no better book (not to say as good a one) for its purpose, on the subject." AN INTRODUCTION TO SPHERICAL AND PRACTICAL ASTRONOMY By DASCOM GREENE, Professor of Mathematics and Astronomy in the Rensselaer Polytechnic Institute, Troy, N.Y. NW. Cloth. Illustrated. viii + 158 pages. Mailing price, $1.60; for introduction, $1.50. The book is intended for class-room use and affords such a preparation as the student needs before entering upon the study of the larger and more elaborate works on this subject. The appendix contains an elementary exposition of the method of least squares. Daniel Carhart, Act. Prof. Mathematics, Western Univ. of Pa., Allegheny, Pa.: "Professor Greene has supplied that which is needed to make the usual course in Astronomy in our colleges more practical." Rodney G. Kimball, Polytechnic Institute, Brooklyn, N.Y.: "The hasty examination which I have given it has left a very favorable impression as to its merits as a judicious compound of the practical work which it professes to cover." SCHEINER'S ASTRONOMICAL SPECTROSCOPY Department of Special Publication.--Revised Edition. Translated, revised and enlarged by E.B. FROST, Professor of Astronomy in Dartmouth College. 8vo. Half leather. Illustrated. xiii + 482 pages. Price by mail, $5.00; for introdoctiort, $4.75. This work aims to explain the most practical and modern methods of research, and to state our present knowledge of the constitution, physical condition alld motions of the heavenly bodies, as revealed by the spectroscope. Edward S. Holden, Director of the Lick Observatory, Mt. Hamilton, California: "I congratulate you on the appearance of this very important book; it is indispensable to all astronomers and students of spectroscopy." ELEMENTS OF PLANT ANATOMY By EMILY L. GREGORY, Professor of Botany in Barnard College. 8vo. Cloth. viii + 148 pages. Illustrated. Mailing price, $1.35; for introduction, $1.25. This book is designed as a text-book for students who have already some knowledge of general botany. It consists of an outline of the principal facts of plant anatomy, in a form available not only for those who wish to specialize in botany but for all who wish to know the leading facts about the inner structure of plants. It affords a preparation for the study of the more intricate and difficult questions of plant anatomy and physiology, while it is especially adapted to the wants of students, who need a practical knowledge of plant structure. ELEMENTS OF STRUCTURAL AND SYSTEMATIC BOTANY For High Schools and Elementary College Courses. By DOUGLAS H. CAMPBELL, Professor of Botany in the Leland Stanford Junior University. 12mo. Cloth. ix + 253 pages. Price by mail, $1.25; for introduction, $1.12. The special merit of this book is that it begins with the simple forms, and follows the order of nature to the complex ones. PLANT ORGANIZATION By R. HALSTEAD WARD, formerly Professor of Botany in the Rensselaer Polytechnic Institute, Troy, N.Y. Quarto. 176 pages. Illustrated. Flexible boards. Mailing price, 85 cents; for introduction, 75 cents. ELEMENTARY METEOROLOGY By WILLIAM MORRIS DAVIS, Professor of Physical Geography in Harvard College. With maps and charts. 8vo. Cloth. xi + 355 pages. Mailing price, $2.70; for introduction, $2.50. This work is believed to be very opportune, since no elementary work on the subject has been issued for over a quarter of a century. It represents the modern aspects of the science. It is adapted to the use of advanced students, and will meet the needs of members of the National and State Weather Services who wish to acquaint themselves with something more than methods of observation. The essential theories of modern Meteorology are presented in such form that the student shall perceive their logical connection, and shall derive from their mastery something of the intellectual training that comes with the grasp of well-tested conclusions. The charts of temperature, pressure, winds, etc., are reduced from the latest available sources, while the diagrams freely introduced through the text are for the most part new. A.W. Greeley, retired Brigadier General U.S.A., and formerly Chief of Signal Office, Washington: "A valuable and timely contribution to scientific text-books." Winslow Upton, Professor of Astronomy, Brown University: "The best general book on the subject in our language." Wm. B. Clark, Professor of Geology, Johns Hopkins University: "An excellent book and of great value to the teacher of meteorology." David Todd, Professor of Astronomy, Amherst College: "Clear, concise, and direct. To teach meteorology with it must be a delight." MOLECULES AND THE MOLECULAR THEORY OF MATTER Department of Special Publioation. By A. D. RISTEEN. 8vo. Cloth. Illustrated. viii + 223 pages. Retail price, $2.00 This work is a complete popular exposition of the molecular theory of matter, as it is held by the leading physicists of today. Considerable space is devoted to the kinetic theory of gases. Liquids also are discussed, and solids receive much attention. There is also a division discussing the methods that have been proposed for finding the sizes of molecules, and here, as elsewhere throughout the book, the methods described are illustrated by numerical examples. The last division of the book touches upon the constitution of molecules. The subject is everywhere treated from a physical standpoint.
