tially successful. H e has provided the novice with details of a number of methods which have been widely used by air pollution chemists. This pro cedure saves the novice the bother of going to the current literature, b u t it denies him to some extent the knowl edge of current critical assessments of methods and information regarding re cent developments which tend to be important in a field such as this which is changing rapidly. T h e author gives some assessment of interferences, limits of accuracy, and other typical consid erations b u t this is at a minimum, no doubt, with the intention of simplifying the position for t h e novice and holding the work to one-volume size. I n , for instance, t h e case of fluorine, such a procedure has a disarming simplicity for it is well-known that much contro versy surrounds techniques for this ele ment. The experienced analyst is less likely to be satisfied with this t y p e of book. The book is published in 1960 but there is only limited reference to new work in 1958 a n d 1959. T h e experienced will, therefore, in many instances be forced to review the literature for three yearsback. This is doubtless a problem in programming the production of any book but if handbooks are to be of real value, t h e publishing industry will have to overcome this problem. I n this con nection one of the notable bibliographic omissions is the author's failure to refer to the biennial reviews of ANALYTICAL CHEMISTRY

on applications to the air
pollution field which have appeared m the April ( P a r t I I ) issues for 1957 a n d 1959. Some persons m a y find the biblio graphic arrangements disappointing, as references are grouped a t the end of chapters, and furthermore they are not alphabetically arranged. There are a great many references to papers pre sented a t meetings. It is difficult for readers to secure copies of papers pre sented at meetings, especially when ex tensive time has elapsed. F u r t h e r m o r e , one wonders whether papers presented at meetings are of lasting value if they remain unpublished for several years. The author has covered most of t h e important areas of his subject. T h e t r e a t m e n t of hydrocarbon analysis is fragmentary and this is peculiar con sidering t h e role which has been as signed to these substances in eye-irritat ing smog production and carcinogenic effects. Arsenic is a notable omission in view of its incrimination in a number of air pollution cases. For all its faults, the presenre of this book in his collection will be reassuring to the hard-pressed air pollution official.
