to implement these teaching activities. The present volume (Volume I) cov ering nmr and ir spectrometry and a projected volume covering mass, esr, and uv spectrometry grew out of sum mer institutes at Salford, England. They are a welcome addition to the list. The strong features of Volume I are the extensive correlation tables and a num ber of worked-out problems (11 for nmr and 14 for ir). The decisions to split the presentation into two volumes and to include the rather specialized esr technique seem unwise, considering the consequent cost increase. The second volume will contain prob lems involving the combined use of the methods presented. In my experience, it is the complementary aspects of the spectral probes that make their use so effective and catch the students' inter est. The emphasis on this complemen tarity and on a "Sherlock Holmes" ap proach to structure elucidation should come as early as possible, even at some initial sacrifice in expertise in an indi vidual area.

Now that the determination of trace elements in biomaterials is experiencing an upsurge, this monograph appears at an opportune time. It falls in that category of books whose authors have been able to draw on their own experi ence as well as on the contents of li brary shelves. The studies of Gorsuch on losses of trace elements in the de struction of organic matter, based on the use of radioactive nuclides, are well known. This method is examined. Ac counts arc given of wet oxidation, dry oxidation, oxidative fusion, and cog nate methods, with comparison of their advantages and drawbacks. More than half of the monograph deals with the behavior (recovery) of some 50 individual metals and metal loids, particularly at trace levels in the destruction of organic matter. The working analyst will be grateful for suc cinct directions for the more important decomposition procedures: digestion with nitric-sulfuric acid, perchloric acid mixtures and sulfuric acid-hydrogen peroxide, and by dry ashing. This book is a valuable source of in formation, eclectic in approach, and compact in presentation.

Wall Mounting Bracket— With Research Cartridge $ 2 4 . 9 5 With Universal Cartridge $ 2 2 . 9 5
With IWT Cartridges, the pure water flows freshly (5 gph) from the ion ex change cartridge. Only a length' of plastic hose links the pure water with the point of use. No contamination can take place. The solvent hunger of pure water has nothing to feed on: no meters; no metal; no storage tanks; no aircarried impurities. PURITY CAN BE 15 MEGOHMS/CM A Duplex Mounting Fixture with two Research cartridges in series even re moves silica and C 0 2 comparing favor ably to triple distillation. A single Uni versal Cartridge delivers water as good as single distilled but silica and C 0 2 re main. Both kinds indicate by a color change when resins are exhausted. Then you merely replace the cartridge for $ 12.95 (Research) or $ 10.95 (Universal). Bui. DX-470 describes the expanded IWT cartridge line. Five different models meet the need for varying levels of purity. Six page, 4-color bro chure describes fixtures, suggests systems, and contains prices. Yours if you ask for it.
