This introduction furnishes a conceptual framework on which to hang the snccecding chapters, gives the hook unity, and helps place the subject matter in context as a branch of physical organic chemistry. One gets the impression that the authors have considwed carefully the comments and criticisms of reviewers of the earlier book. The result is not perfect, but one does not find in it a, great deal to criticize. A number of statement,s have been para-

The point of view of this new series, as expressed b y the editors in the Intraduction, is that ehelatiou is a "prominent chemical principle" which can serve "to unify a large area of analyt,ical chemistry." The editors stato flirther: "No grand scheme has been devised. Instead, an &tempt will nsoally be made to treat dissimilar topics within n single voh~me.. . . Same overlap of information from one article to another may occur, (but) it is hoped that as the number of valnmes in this series increases, a comprehensive treatment of chelating agents and chelates in analytical chemist,ry will he approached -at least asympt,otically." Volume I does present a diverse collection of topics, each treated with competence. Aft,er a. hrief history of analytical methods based on complex formation (including complexes wit,h monodent,at,e ligands, not generally treat,ed in this series), by F. SaabadvAry and M. T. Beck, there follow seven monographs ranging in length from 26 to 01 pages, with an average of one page of references per 10 pages of t,ext. The volume has a deliberate international flavor-of the eight sections, the authors of four are irom Csechodovakia, with Anstrin, Germany, I-Tungsry, and t,he USA each represented by one section. The v d ~ ~ mhas e ovwall ant,hor and subject indexes, and c~~mnletive indexes are planned. T'ery few errors were ionnd. Fonr specialized topics are t,xeated with relative completeness: Xylenol Orange m ~ d Methylthymol Blne, by B. BndE8inskjr, adds a new dimension to the use of these reagents as metallochromic indicat,om in ehelometric titrations: reactions with fifty different, met,al ions are t,t.eat,ed, with an amazing correlation between calc~daled and ohserved optimum pH values for complex format,ion.
