Noyes's Co lege Text=Book of Chemistry

By W. A. NOYES, Professor in the University of Illinois 336 pages of text. l2mo

This College Textbook of Chiemistry is designed, more'es- pecially, for students of the freshman or sophomore years in college who have not studied chemistry in high school. It is considerably briefer than the author's previous Text- book ot Chernistry, and its style is exceptionally clear aild simple.

As with all textbooks for beginners, two purposes have beell constantly kept in mind while writing the book: the presentation of a few of the multitude of chemical facts which touch our modern life, in such a manner that they can be clearly understood, and the discussion of the theories and principles around which all our chemical knowledge is grouped.

The teacher of chemistry is embarrassed by the vast and ever increasing amount of knowledge at his disposal and is often tempte(l to presernt many more topics than the student can possibly remember. In trying to avoid this difficulty nmany facts ordinarily included in an elementary textbook have been omitted and those which are given are brought as far as possible into close logical relations.

The summary at the close of each chapter is a somewhat unusual feature of the book. It is hoped that these sum- maries will be found useful.

Success in the study of chemistry depends especially on the ability to learn new facts in their relation to those which have alrea(dy been acquired and on the cultivation of a logical as distinguished from an arbitrary memnory. The exercises at the close of each chapter and questions occasionally inserted in the text are designed to assist the student in this direction.

Quantitative Analysis By GEORGE MCPI-IAIL SMITH, Professor of Chemistry in the University of Washington (recently at the University of Illinois). Cloth, Octavo, 206 pages. $I.75.

This new text-book in Qiuaititative Chemical Anialysis is thorouglh and well-ar- ranged. It includes full laboratory instructions as well as the material for the lecture- room, and contains carefully chosen types of gravimetric and volumetric analyses. The laboratory directions are explicit and sufliciently detailed to perlmit the student to work largely without supervision. The sections devoted to stoichiometrical problems and to questions upon the subject matter will be particularly welcome to instructors, as they give the student an insight into a wide variety of processes.

A Short Course in Mathematics By ROBERT E. MORITZ, Professor of Mathematics in the University of Wash- ington. Cloth, 12mo, 236 pages.

A text containiing the material essential for a short course in Freslhman mathematics which is complete in itself, and which contains no more material than the average Fresllman can assimilate. The book will constitute an adequate preparation for further study, and will enable the student to take up the usual course in analytical geometry without any hlandicap.

Among the subjects treated are: Factoring, Radicals, Fractional aind Negative Exponents, Imaginary Qtiantities; Linear and Qtiadratic Equations; Coordlinates, ancl Simple and Straight Line Graplhs; Curve Plotting, Maxima and Minima; Areas; The General Angle and its Measures, The Trigonometric or Circular Functions, Func- tionls of an Acute Angle; Solution of Right and Oblique Trianigles; Exponents and Logaritlhms; The Four Cases of Oblique Triangles; Problemis In-Nvolviing Triangles.

In Preparation

Plane Trigonometry By JO HN W. YOUNG and F-RANK M. MORGAN, Professors of Mathematics in Dartmouth College. Clotil, 1z2mo, about 120 pages.

This new Plane Trigonometry was prepared to supply the neecl for a brief text emphasizing the numerical aspects and applications of trigonometry. It embodies the characteristic features of the widely approved sectionis devoted to trigonlometry in "Ele- mentary Mathematical Analysis,?' the earlier work by Professors Young and Morgan. The material has been carefully revised, aind fully lhalf of the present book is entirely new. Amon-g the distinctive sections of this Trigonometry are those which explain the use of the haversine. The authors stress the value of computation and of logarithmic tables; and therefore tables of haversiines and otlher niew tables aire included.

A History of the Sikhs From the Origin of the Nation to the Baities of the Suite!

By JOSEPH DAVEY CUNNINGHAM $3.85

The third edition of this valuable work originally issued in 1849 corrected in minor details to con- form with modern knowledge. It provides not only a history of the Sikhs as a people but also places Sikhism in the general history of humanity by showing its connection with the other creeds of India. The author writes from an extended first hand knowledge of the Sikhs gained in the Political Department of the East India Company. As a consequence of criticisms of the Govern- ment in his book he was dismissed from the department and sent back to regimental duty. He died in i85i, aged 39.
