There follow three more sections: detection and clctcrmiiint’ibn of the clc&~c~i&i %(30’ pages), preliminary c.xnminntion and general tests (9 pages) ancl detection and estimation (the Reviewer would prefer the word “clet.crmtnaiion”) of functional groups (299 pages). The last section is obviously the most important one of the book nncl deals with (K) the hydroxyl grou carboiiyl grou compounds,

enormous field within a reasonable space. Compression has necessarily been inevi- tnblc, but very full (and up-to-date) references to the original hterature arc given. In the Reviewer’s opinion, the book will prove not only of great value to University stuclcnts but also to industrial organic chemists who have occasion to ascertain the iclcntlty and/or purity of organic substances.
