Changes in analytical reagent specifications The ACS Committee on Analytical Reagents has reported the following change in the 7th edition of "Reagent Chemicals—ACS Specifications." On page 422, for Mercuric Sulfate, rewrite the procedure for Residue after Reduction, as follows: "Add 5.0 g to 50 mL of water plus 5 mL of formic acid (96%). Stir until all, or nearly all, of the mercuric sulfate is dissolved. Add, dropwise, 10% ammonium hydroxide reagent solution until a permanent precipitate is formed. Digest under total reflux until all the mercury is reduced to metal. Cool, filter through a wellwashed filter paper, and wash with a small quantity of water. Add 0.1 mL of sulfuric acid to the combined filtrate and washings, and evaporate cautiously, to avoid spattering, in a tared dish in a well-ventilated hood. Continue heating until the excess sulfuric acid has been volatilized. Finally, ignite at 800 ± 25 °C for 15 minutes. Correct for the weight obtained in a complete blank test. Retain the residue for the test for Iron." Any suggestions concerning this item, or suggestions for additional reagents and testing methods, may be directed to the committee chairman, Clarence Lowery, 492 Old Decoursey, Independence, Ky. 41051. •
Papers for nuclear fission conference The American Chemical Society is cosponsoring a conference on "50 Years with Nuclear Fission," April 26-28, 1989, Gaithersburg, Md. The other sponsors are the American Nuclear Society, the National Institute of Standards & Technology (formerly the National Bureau of Standards), and the American Physical Society. Commemorating 50 years of research on and the application of fission process, the conference will feature a recapitulation of progress by outstanding contributors together with presentations of current re84

search and applications. Topics include fission theory; experiments in support of theory; instrumentation; fission applied data; astrophysical and space applications; fission byproducts in biology and medicine; industrial fission by-product applications; reactor design and development; safeguards; peaceful uses of fission technology; and applications in general research and development. Some of these topics may be presented in poster sessions. A summary of 1000 words (three copies in English) and a 150-word abstract must be submitted by Oct. 1 to Jan Hauber, Conference Secretariat, Room B-109, Bldg. 245, National Institute of Standards & Technology, Gaithersburg, Md. 20899. Summaries should include an introductory statement indicating the purpose of the work, and a closing statement delineating significant results or conclusions. For further information, contact the Conference Secretariat in Gaithersburg, (301) 975-5567. •
AIC sponsors exchange visit to U.S.S.R. Chemists, chemical engineers, and their guests are invited to participate in a 13-day scientific exchange visit to the U.S.S.R. Scheduled to begin June 14, 1989, the trip is being sponsored by the American Institute of Chemists. Participants will arrive in Moscow on June 15 and engage in scientific interchanges with Soviet colleagues, as well as visit cultural and historic landmarks. On June 19, the tour will travel to the resort city of Tblisi, and then fly to Leningrad before departing for Amsterdam on June 25. The price of the trip is $3200 per person, and includes all expenses. There is an additional AIC Foundation registration fee of $100 per person. Send a one-half page curriculum vitae, a one-page statement on a topic you would be prepared to present or discuss with Soviet scientists, and a $350 deposit by Dec. 1 to AIC Foundation, 7315 Wisconsin Ave., Bethesda, Md. 20814, phone (301)652-2447. •
Cancer: The Outlaw Cell
C
ompletely revised and updated! Since the first edition of this bestseller was published over ten years ago, amazing progress has been made in the battle against cancer. This new edition presents information from leading scientists on some of the most promising aspects of cancer research and clinical treatment. Many of the original writers have completely revised their chapters to reflect the current situation. Other topics, such as angiogenesis, are introduced here for the first time. The underlying theme stresses the basic concepts of biology and medicine and their influence on the experimental study of cancer cells in the laboratory test tube. Throughout the 14 chapters of the book, you'll learn more on • theories about how cancer develops • how the body cooperates or fights back with a malignancy • chemicals and radiation • angiogenesis
plus many approaches such as immunotherapy that are being used successfully today Cancer: The Outlaw Cell is written in clear, non-technical language. It will be a help for anyone whose life is touched directly or indirectly by cancer. Students as well as the educated public interested in learning more about cancer will find this book an authoritative source of information on one of the most devastating diseases of our time.
