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, 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. Here, io the space indicated. "seventy different learning and curricular studies" by Mty-seven different authors are abstracted and placed in a readily aece%sihleform. I t is surprising what a compass the phrase "learning and evrricuiar studies" can cover.

In the preface the author promires "other vo1umer bringing the work up-to-date." I t would he very helpful if a companion volume could he prepared giving a similar treatment to studies of tests for science subjects: the labore.. tory,itsequipment, arrangement,and administmtion; the science teacher, his job and his preparation for it. However. Doctor Curtis has, in this volume, made a distinct contribution t o the growing number of helpn for the science teacher.

The questions and problems a t the end of each chapter are exeellent.
