An Introduction to Chemical Science Part 29

"It seems to me the book is admirably adapted to its purpose, and that it accomplishes the difficult task of presenting to the student or reader not conversant with Algebra and Geometry, an excellent selection of what may with profit be given him as an introduction to the science of astronomy."

YOUNG'S ELEMENTS OF ASTRONOMY

With a Uranography. By CHARLES A. YOUNG, Professor of Astronomy in the College of New Jersey. 12mo. Half leather. x + 472 pages, and four star maps. Mailing price, $1.55: for introduction, $1.40.

Uranography.

From Youpg's Elements of Astronomy. 12mo. Flexible covers. 42 pages. besides four star maps. By mail, 35 cents; for introduction, 30 cents.

This volume is an independent work, and not an abridgment of the author's General Astronomy. It is a text-book for advanced High Schools, Seminaries, and Brief Courses in colleges generally. It was prepared by one of the most distinguished astronomers of the world, a most popular lecturer, and most successful teacher. It had every presumption in its favor, and the event has more than justified expectations. Special attention has been paid to making all statements correct and accurate so far as they go.

In the text no mathematics higher than elementary algebra and geometry is introduced; in the foot-notes and in the Appendix an occasional trigonometric formula appears, for the benefit of the very considerable number of High school students who understand such expressions.

G.B. Merriman, formerly Prof. of Mathemutics and Astronomy, Rutgers College, New Brunswick, N.J.:

"For a short course in elementary astronomy, it is by far the best book I have ever examined."

Warren Mann, State Normal School, Potsdam, N. Y.:

"Accuracy in use of terms is a marked feature. I consider it the best text-book on this subject."

H.N. Chute, High School, Ann Arbor, Mich.:

"It is just the book the scholars have been waiting for."

G.H. Howe, State Normal School, Warrensburg, MO.:

"It is indeed an admirable book, up to the times, clear, and complete."

Jeremiah Sloc.u.m, South Division High School, C&ugo, Ill.:

"It is well adapted both as to scope and manner of treatment to high-school work."

Ray G. Huling, Prin. of English High School, Cambridge, Ma.s.s.:

"It is delightfully fresh, full, and clear."

A.S. Roe, recently of High School, Worcester, Muss.:

"The book is extended enough to please the exacting teacher."

I.P. Bishop, State Normal School, Buffalo, N.Y.:

"The book seems to have all the essentials of a first-cla.s.s text for high school work; viz., conciseness, clearness, and the results of recent research."

YOUNG'S GENERAL ASTRONOMY

A Text-book for Colleges and Technical Schools. By CHARLES A .

YOUNG, Professor of Astronomy in the College of New Jersey. 8vo.

viii + 551 pages. Half morocco. Ill.u.s.trated 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 cla.s.ses, 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 Inst.i.tute, Troy, N.Y. NW. Cloth.

Ill.u.s.trated. viii + 158 pages. Mailing price, $1.60; for introduction, $1.50.

The book is intended for cla.s.s-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 Inst.i.tute, 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. Ill.u.s.trated. 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 const.i.tution, 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."
