BOOK REVIEWS bromine in CCL added to tubes containing pentane and pentene would rtooomplish this beautifully and almost instantly. Within a few pages in the organic section the student is required t o describe the odors of fourteen organic compounds. This is a difficult, if not a n impassible, task since some have odors characteristic only t o themselves. Somewhat misleading is the number of experiments listed; 133 are contained within 94pages of the book. Experiments 108, 109, and 110 with space for answers utiliae one-half of one page. Experiments 111 t o 124 are on normal and pathological urine. The manual is the fill-in type with a place for every answer and many whale pages are required t o be filled in with physical and ohemicrtl properties of numerous chemical compounds. A mass of data is to be recorded but little or no attempt a t generalization is made. The reviewer's experience with courses of the type for which this manual was written leaves doubt in his mind of the ability of many of the students enrolled in suoh courses t o prepare formal labaratory reports such a s required in many manuals. If the student, unfamiliar with science, must be led through his experim e n t ~ ,then certainly a n attempt should periodically be made t o orient the student with respect t o the place and importance of the particular experiment with regard t o the course. Certain questions should

Arsenic, antimony, end bismuth from elements of Group V are treated in this volume. The general description and physical properties of arsenic and its inorganic compaunds are presented by R. Dolique, while the organic compounds are described by Pasoal himself. Bothorel is sole author of the section on antimony, and Domange is sole author of the material on bismuth. Comparison with other volumes of the treatise which have appeared previously shows that generally high standards are being maintained, but most of the criticisms may still be applied, such a s poor indexing, failure t o select a single date (1956-58) t o which t o bring all literature searches for the entire volume, and the like. As with the other volumes, coverage

is more extensive than that of Mellor but not as extensive as that attempted in Gmelin. The advantage over both is that the more modern concepts and materials from recent publications are being used in Pascal. ROGERV.

This volume of Pascal on chromium, molybdenum, and tungsten meets a ~ressingneed for a more comprehensive reference work a n these elements. The volume of Mellor which included them appesred in 1931, and the current edition of Gmelin does not yet include chromium. I n the latter set, tungsten appeared in 1933, and molybdenum in 1935, while supplements t o bring the literature surveys to 1950 have not yet appeared. An introduction to the three elements has been vritten by Pascal, and this is followed by the section on chromium by J. Amiel, with a description t o the complexes of chromium by Raymonde and Clement Duval. Exoept for a discussion on molybdates, molybdio anhydrides, and molybdic acids by L. Malaprade, the (Continued on page A848)
