BOOK REVIEWS The section entitled Multicomponent Gas Svst,ems contains chapters on Liquefaction and Fractionation of Gases (54 pages), Adsorption (45 pages), and Refvigeration Practice (52 pages). The section on Liqnid-Solid Systems is the most romplete of this particular volume. This seetion contains chapters on Lcsching (20 pages), Crystallization ( 4 4 pngcs), Colloids (41 pager), Filtration (11 pages), Select,ion, Sizing, and Operat,ion of Filters (41 pages), and Centrihiging (39 p"ges). The final section contains the chapter Sublimation and Vacuum Freeze Drying (33 pages). Vohtme G carries on the t,hurnoghncss 3f t h previous ~ five vohlmes.

we understand by chemistry both the pure and applied subject. The contributors are far the most part English, but there are as well two articles from France, two from Russia, one from Wales, and one from Australia, giving the collection an interJ o a J. ~ M c K E ~ national flavor. The purpose of the Uniuersity of Tezas volume is to honor Professor N. K. Adam Austin as he retires far his achievements in the physics and chemistry of surfaces. It was in 1917 that Lmgmuir's classical Surface Phenomena in Chemistry and work on surfaces appeared in print, so the Biology subject to whioh thc "guest of honor" hits Edited by J . F. Danielli, K .

I t s purposeis t o be an This volume gathers together a series historical survey of work done on surface of essays, 23 in number. I t s title is films and soaps; this i t is, but a t the same accurately descriptive of these reports if time in i t the philosopher speaks. The old order is changing and students of chemistry who read Tms JOURNAL will be here made again aware of this situation. Mare than half of the reports deal with subjects in the physical chemistry of surfaces. Many of them are very good critical review articles which perform the function of sorting out positions which could be consolidated from those of weaker foundation. Relatively few fall into the oategory of original research reports, no doubt by intent of the editors. Several of the reports which have t o do with applications t o biology were of special interest t o this reviewer. One of them by Hartley and Brunskill is a study of the physical mechanism of the reflection of water drops from surfaces, a subject of importance in connection with tho application of ineectieides. Another is a oomprehensive review of eel1 membrane physics and chemistry by Ihnielli. Still another by Davson describes tho use of the Gibbs-Donnan equilibrium to study relationships between biological fluids. The editors and authors have done a very nice thing for their eminent scientist friend, Professor Adam. The publishers have produced a n attractive volume and have kept the prioe a t a. reasonable figure for this type of publication. It hss been a successful enterprise and all involved are to he congrstulnted upon their success in providing the ohemied world with a collection of interest and value.
