and the general theory of spectra and of atomic structure. A general chapter on "Statirtics" provides an interpretation of energy ar applied to the modem eooceptsof heat and it=phmomena, discussed in the chapter on "Thermodynamics." "By resolving the object of phyrieal proceses. so-called matter, into an assembly of individual particlea, i t becomes po~sible f m theoretical phyrieo t o investigate all physical phenomena and states by means of methods which are Lnown quite apart from the province of physier ar st=. &ti-l methods." "The Theory of Relativity" deals with the special theory of relativity and the theory of gravitation. together with their ramificationr. In the appndiii sre found a summary of the whole baok by sertionn, and a "brief summary of the more important work carried out between the publication of the German edition and of the present English edition of Val. 11." ~

The purpose of the book is to present a series of study questions and problem^ which will require students to master the principles of organic chemistry and apply them to concrete cases. Although the hook has been written primarily for undergraduates, it includes large amounts of material of valve to graduatbstudents. The author has fulfilled his purpose admirably. Organic ehemirta of all degrees of advancement and proficiency can use the book with pleasure and profit. From the standpoint of chemical education, the book in thoroughly r o m d as far as its primary purpose in concerned. However, each chapter contains introduetoly material whieh is, perhaps. open to criticism in many cases. This is partly

Among the subjeetn taken up are: Fuels and Combustion; Gas producers; Sulfur Compounds: Lime and Cement; Furnace and Kiln Desipn; Metallurgy; Plant Design; and Crystallirstion. As a text-book i t is designed to provide means for enabling the student already versed in the arithmetic of quantitative analysis to become familiar with the technic of the more involved and difficult calculations of industrial ehemirtry. particularly. the computations of cootiouou. processes. But it is meant to serve no less the man in industrial work. The authors' names alone should vouch amply for the quality of this work and the reviewer wisher only to add that it will 611 a need long felt by teachers of chemical engineering for a tertbook on the quantitative aspects of the subject.

As indicated in the preface, this book is intended to correct the deficiency found in hiahschool and college students in the matter of simple chemical calculations. "Both teacher and pupil are handicapped by a dearth of properly graded oroblemn to eo hand in hand with the r e ~ u l a r daily assignment.. . .The aim of this baok i s to 611 the gap whieh teachers of chemistry in secondary schools have felt e&ts in moat of the text-books used.. .Problems in this book are p~~gressivcly arranged according to a number of types which the student soon learns to recognize. They are a130 graded according to the degree of dimculty and order of leeson assignment.. .
