THE sixth edition of this well-known book requires no introduction, and it is a pleasure to note that Dr. Nicholls, who was responsible for so much good work in his revision of the previous edition, has now become the recognized author. This edition, which has been increased in size by about one third, contains several new sections ; in addition, previously existing sections have been extended and revised. Many references to recent original work recorded in The Analyst and elsewhere have been included, and these alone make the book of great value to the practising analyst. The great majority of the new sections have been added to the chapters dealing with food ; drugs now occupy only about a tenth of the book, an even smaller proportion than formerly. One might almost suggest that they could be omitted altogether ; the book could then be removed from the “aids” series nd published in more pretentious form as a text-book on food analysis.
