stresses the value of a high equwalent weight m a standard substance, yet occasionally specifies quantities which are unreahstmally small for elementary work; and when her descrlptlon of the neutrahsatlon curve of phosphoric acid goes beyond what can be seen m her diagram But these are mmor blemishes m an excellent book The student who uses It will proceed with confidence to any of the standard works mentioned m the short blbhography The book 1s well printed and strongly bound. A few additional pages m a subsequent edmon would enable the author to Improve the exposmon m places and thereby increase the usefulness of the book to students J McG. JACKSON
The Routine Analysis of Copper Base Alloys. FRANK J VERSAGIChemmal Pubhshmg Co Inc , New York, 1960. pp 168 $5 00 THIS slim volume IS a collection of methods of analysis likely to prove useful to those for whom the author states it IS mtended Even though “theroretlcal” chemistry has been deliberately excluded as far as possible, it IS dlsqmetmg to find to be inaccurate some of the little there IS. For example on p 70 we are told that alummmm precipitates from a solution made alkaline with 10 ml of saturated caustic soda solution, and on p 71 that “bodmg with sodium hydroxide drives off the rutrlc acid ” The statement on p 15 that for routme work it IS never necessary to weigh beyond four slgmficant figures IS obviously nonsense when electrolytic methods are used as often as m copper alloy analysis. On the practical side, one may ask what 1sthe purpose and effect of adding 1 drop of 0 1N hydrochloric acid to the electrolyte before determmmg copper (p 30). The book 1snot free from typographical errors, the worst being the misplacement of a whole lme on p 157, and the consistent use throughout of Mu for rnp Although the book undoubtedly achieves Its avowed alms, one wonders whether they are completely desirable ones or whether It would be better to follow Hdlebrand m wishing to produce analytical chemists rather than chemical analysts Finally, five dollars seems a lot to pay for 168 pages, 20 of which are completely blank, being unsullied even by the page numbers they should bear R A CHALMERS
