DETROIT MEETING OF THE A. C. S. D M S I O N OF CHEMICAL EDUCATION Tentative plans for the fall meeting of the Division of Chemical Education are already taking shape. At present these plans include a symposium on the popularization of chemistry, an inspection trip t o East Lansing t o inspect the new chemistry laboratory of Michigan State College and three half-day sessions devoted t o the presentation of miscellaneous papers. Dr. R. A. Baker, secretary of the Division, announces that no papers can be included in the program unless abstracts thereof reach his office, Bowne Hall, Syracuse University, Syracuse, N. Y., by July 15th. 0. E. Madison of Detroit'has just been appointed Assistant Secretary of the Division for the Detroit meeting. He will aid in the arrangement of the local details of the program.
