AS stated by the authors, this book is intended for college and university students and represents the combined e5of experienced teachers of chemistry. The subject-matter is taken up in fifty well-selected chapters and is treated in modern fashion. Most of the chapters are followed by pertinent study questions and in a few instances references for r~pplementaryreading are given. There i n considerable repetition, although in most inStanCEs where a subject ir repeated i t is a p proached from a different viewpoint and by a different author.

This, no doubt, is a printer's error, but many sections of the book seem t o have beem printed without being subjected to careful prod-reading. Many of the cuts have been made from free-hand drawings and although they show what is intended, they add to ooe'r feeling that the book. as it stands, represents an unfinished piece of work. Much .-ace has been used in reproducing photographs of minerals and mineral products and there is scarcely an instance io which such cuts show anything of value. The index, a maat valuable part of any serviceable text-book. is wholly inadequate. T h e paper and binding are not first I Until this book har been subjected to considerable editmial and mechanical refinement, it cannot be expected to assume a place of importance among the text-books of geoernl chemistry.

"A

The eutomarJ, grouping of the experiments ha* been followed. Gravimetric methods are illustrated by 23 determinations, loeluding representative elcetrolytie determinations. Volumetric procedures are illustrated by 29 d e t e r minations and are subdivided in the customary manner to include procedures bared oo neutralization, oxidation, iodimetry, and colorimetry. Three proeeduren illustrate the deter. minatian of minute amounts of rubntanees. Interspersed throughout the text matfevare lists of carefully prepared questions and problems. "The methods selected are standard proeedurea having the advantages of amuracy coupled with rapidity." The first experiments deal with simple determinations in which interfering rubstances are absent. I n later experiments. separations and more difficult manipulations are required. There are no complete ore or rock analyrea described. I n eonoeetion with the determination of various of the elementary substaoces, intmdudory notes state the importance of the substance as a reason for its determination. The principle back of the determination is given brieny and references for the further study of the theoretical principles are listed.

the selection of those experiments whieh are best suited t o the needs of the individval course. The hook is well-written; the directions are clear and specific; and numerous helpful hints are given lor the aid of t h e student. By thoughtfully following the directions given for each determination, the student should be able t o obtain good results and should acquire the habit of cmreet manipulation. In the opinion of the re. viewer, the author has provided n excellent manual, and one which will be fotmd very useful i n college cour.es, in whieh the inexperienced student finds the more complete treatiees on the subject rather clrmbersome far his work. The author does not attempt t o d i r u r r fully the theoretical arpects of the subject, and the hook does not purport to he a dass-room tert. m to develop this important ,,base of the course in quantitative analysis, there will he required a wries of lectures and emphasis upon the collateral readings to which the author refers.

The appearance d the seeand edition of this well-known work will be a sowee of gratification t o the many users of the erst Edition. Proferror MaeDougsll has completely rewritten the c h a p ters on Ionic Equilibria, Electromotive Force, and the Third Law. An extensive discurrion of the Debye and Huckel theory has brought the presentation of t h e first two subjects thoroughly up-to-date, while a new treatment of the Third Law will render i t more readily grasped by students. In addition certain minor alterations have been made in other ehnpters. The arrangement of subjects renders this hook very ureful from the pedagogical standpaint After three chaotcrs of fundamental coneentr. . . etc., the First Law is discussed, followed hg itn eonreqllences and applications. In the same manner the author takes up the Second and Third Laws. This leading up t o and discnuion of practical applications is so thorovghly done that few students will remain vneonvineed of "the

For one interest~din science teaching, who has spent hours running down some promising reference perhaps to find that the results sought are scattered through pages of uoderirahle detail or the volume containing the article not available, the book under review will find a ready nelcome.
