THIS welcome compilation of data and derived values for thermodynamic and transport properties of air, A, C02, CO, Hs, Ns, Oz, and HzO should be made itvitilable to every professional and student chemist. I'rofessors of physical chemistry will find the ceiling lifted on the type of problems they can assign to stn-
Tam book can be recommended t o the analyst as a practical guide in the selection of proved organio reagents for use in inorganic analysis. The book is critical rather than oomprehensive. I t consists of a collection of nome 27 monographs dealing with selected reagents. The selections are good and the conclusions drawn concerning them are quite well substantiated. The title of the hook is too restricted, ineidentally, because the Karl Fischer reagent for water is included as arc reagents such as nitron and indanetrionn hvdmte
