SINCE it was first published in 1937 this volume has been one of the ~ t a n d a r d references for lecture demonstrators. At first glance the first 435 pages appear to he identical m+th the third edition. (J. CHEM. EDUC., 27, 170 (19.50)). This is somewhet misleading. The literature references a t the end of pages 12 and 13 have been revised and additions made. On page 19, experiment 5A, the gaseous diffusion of hydrogen chloride and ammonia has been added and four pages inserted as 19A, B, C, and I), which contain experiments dealing with the motion and diffusion of molecules snd ions in gels, tho dependence of the rate of diffusion on temperature, and an introduction to dialysis and Brownian movement. Numerous footnotes have been added throughout the text. On page 436 the electrolysis of molten silver nitrate has been added. Chapter 6 from the third edition, Physical Principles and Common Phenomena, has been subdivided into three additional new chapters. Chapter 7, Surface Chemistry, in which the material from the third edition on the calloidnl state has been largely rearranged uith new material added dealing with gaseous and vapor absovption, ion exchange, water softening, shsorption of dycs, and paper ehramatography. Chapter 8, Catalysis, is essentially a portion of the aame material which was previously included in Chapter 6. Chapter 9, Flame Combrtstion and Explosion, is also m a t e rial from Chapter6of the previous edit,ion. An addendum incorporating recent views and more recent rcfcrenc~sha8 heen added to the first appendix entitled The Aims and Methods of Teaching. Two supplements appear as in the third edition with the exception that additional expermcnts on the conductivity of water, the electrolysis of distilled \-atel., and the preparation of cuprammonium rayon and two (Conlinued on page A l S 6 )

I m p s of nates referring to varioor c.zlwim m t s have been added to part two. One ~.ouldnormally anticipate in a Irevised and enlarged edition that matr~.isls m r h as that inrluded in the sopplmwnts might have been vorked into the text nt the appropriate place f w logical srqwnce. Hawrvor, perhaps wr ahauld not 1 , ~too wibical of a n author and publisher who have perai~ted in suppl,ving chemistry teachers with an excellent hook on 1rctrlt.r dmnonstrations. They should not lr! m~t,igatndfor using the most inexpensive r a y possihle of preparing a new edition. At least this is far hettev than the situation in our own country where tu-o or thvw ~ r c e l l e n tbooks on lecture demonstlalions in chemistry have gone out of print and have long since been onavsilahlc a n the market,.
