SUGGESTED Course of Study in High-School Chemistry" sponsored by the Division of Chemical Education of the American Chemical Society is one of the outcomes of the 1940 summer Workshop in Chemistry a t the Western Reserve University. A copy of the outline will be sent to all teachers who will use it as a basis for t e a c h g and critical study. More information can be obtained from Martin V. McGiI1, Lorain High School, Lorain, Ohio.

The Second Summer Conferenceof the New England Association of Chemistry Teachers, held in August a t the University of Maine, was one of the outstanding events in chemical education in the East during the summer, due largely to the work of Chairman Theodore C. Sargent of Swampscott, Massachusetts, and his committee. Thirty-five discussion leaders appeared a t the ten sessions before a total attendance of well over two hundred. A complete social and recreational program was featured also. The association has accepted the invitation of the University of Connecticut to hold the Third Summer Conference a t Storrs, Connecticut, in August, 1941. George B. Savage of Loomis School, Windsor, Connecticut, is chairman, and Professor Lawrence H. Amundsen of the host institution is in charge of local arrangements.

D O F S hydrogen sulfide act on silver? The response to the inquiry1 about the equation

which apparently contradicts the electrochemical replacement series of themetals appears to be that the equation is incorrect. ' Basing his statement upon extensive experimental data upon this topic, Dr. C. E. White of the University of Maryland reports2 that he and S. Lilienfeld could detect no hydrogen from this reaction a t room temperature; and that unless air and moisture both were present silver was unattacked by hydrogen sulfide eicept a t high temperatures. Evidence is brought forward to support the view that the hydrogen sulfide in solution is oxidized to sulfur. The sulfur then joins the silver readily. , ' J. CHEM.EDUC..17, 118 (March. 1940) *I.Am.
