Noyes's College Text= Book of Chemistry

By W. A. NOYES, Professor in the University of Illinois 336 pages of text. 12mo

This College Textbook of Chemistry 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 of Chemistry, and its style is exceptionally clear and simple.

As with all textbooks for beginners, two purposes have been 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 tempted to present many more topics than the student can possibly remember. ln trying to avoid this difficulty many 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 already been acquired and on the cultivation of a logical as distinguished from an arbitrary memory. The exercises at the close of each chapter and questions occasionally inserted in the text are designed to assist the student in this direction.

A History of the Sikhs From the Origin of the Nation to the Battles of the Sutlef

By JOSEPH DAVEY CUNNINGHAM $3.85

The third edition of this valuable work originally issued in 1849 corrected in minor details to con- forn 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.

Quantitative Analysis By GEORGE MCPHAIL SMITH, Professor of Chemistry in the University of Washington (recently at the University of Illinois). Cloth, Octavo, 206 pages. $1.75.

This new text-book in Quantitative Chemical Analysis is thorough 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 sufficiently detailed to permit 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, 1 2mo, 236 pages.

A text containing the material essential for a short course in Freshman mathematics which is complete in itself, and which contains no more material than the average Freshman 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 handicap.

Among the subjects treated are: Factoring, Radicals, Fractional and Negative Exponents, Imaginary Quantities; Linear and Quadratic Equations; Coordinates, and Simple and Straight Line Graphs; Curve Plotting, Maxima and Minima; Areas; The General Angle and its Measures, The Trigonometric or Circular Functions, Func- tions of an Acute Angle; Solution of Right and Oblique Triangles; Exponents and Logarithms; The Four Cases of Oblique Triangles; Problems Involving Triangles.

In Preparation

Plane Trigonometry By JOHN W. YOUNG and FRANK M. MORGAN, Professors of Mathematics in Dartmouth College. Cloth, i 7mo, about 120 pages.

This new Plane Trigonometry was prepared to supply the need for a brief text emphasizing the numerical aspects and applications of trigonometry. It embodies the characteristic features of the widely approved sections devoted to trigonometry in "Ele- mentary Mathematical Analysis," the earlier work by Professors Young and Morgan. The material has been carefully revised, and fully half of the present book is entirely new. Among 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 haversines and other new tables are included.
