SCOTSMAN :—" It is admirably suited for laboratory use. No other book in the English language covers the same ground." CHEMICAL TRADE JOURNAL:-"The work is well arranged, and constitutes a source of practical information upon the handiest and most reliable methods for use in technological gas analysis."

ENGLISH TRANSLATION OF MEYER'S HISTORY OF CHEMISTRY.

By ERNST VON MEYER, Ph.D., Professor of Chemistry in the University of Leipzig. Translated, with the Author's sanction, by GEORGE MCGOWAN, Ph.D., Demonstrator in Chemistry, University College of North Wales, Bangor.

SPEAKER: "A standard book on the subject. The conclusions are obviously the outcome of wide knowledge, independent research, and sound judgment.”

A NEW TRIGONOMETRY FOR SCHOOLS.

Now Ready, Crown 8vo, Cloth, 6s. 6d. ; or in Two Parts, 3s. 6d. each.

THE ELEMENTS OF PLANE TRIGONOMETRY. By RAWDON LEVETT and C. DAVISON, Masters at King Edward's High School, Birmingham. In Two Parts.

This book is intended to be a very easy one for beginners, all difficulties connected with the application of algebraic signs to geometry and with the circular measure of angles being excluded from Part I. Part II. deals with the real algebraical quantity, and gives a fairly complete treatment and theory of the circular and hyperbolic functions considered geometrically. In Part III., complex numbers are dealt with geometrically, and the writers have tried to bresent much of De Morgan's teaching in as simple a torm as possible.
