advantages and disadvantages of each technique are not covered adequately and while problems surrounding whether or not to wash hair before analysis and the difficulties due to the variation of trace elements over a single head are properly discussed in the book, the attempts which have been made by numerous authors to carry out a statistically meaningful interpretation of the results are omitted. Arsenic, which has received considerable attention in forensic science because of its importance in cases involving suspected poisonings, receives scant attention in the book. There are obviously typographical errors; “anagen”, for example, is frequently misspelled and there are other errors too many to mention here. This is not a book that I could warmly recommend. It would be of limited value to those forensic scientists who have already made a detailed study of hair or who are trying to characterise hair by trace element analysis. However, those who want some light background reading about hair are likely to find it a helpful and readable book. Eric Pearson Toxicology Annual Volume 3 Edited by C. L. Winek. Publisher: Marcel Dekker, New York, 1979, pp. 356, price Sfr. 90 The present volume 3 comes close to the preceding volumes in appearance and editorial design. It consists of a collection of surveys and articles on a wide variety of topics, which have nothing or very little to do with each other. To give an impression of the contents it will be necessary, therefore, to cite the topics covered in this book: Toxicity of pyrithiones, of poinsettia (which is completely non-toxic), of heroin, phthalate esters, fluorescent whiteners, chloroprene and organochlorine pesticides (carcinogenicity), tin hydroxide, ethylene glycols, and of poisonous plants in Sudan. In addition, the use of the uricase-inhibited rat in studies of gout and the use of propranolol as a cocaine antagonist. Each subject is treated by experts in that particular field, ensuring thorough and up-to-date information for the reader.
