The University of Pennsylvania Press is initiating an annual publication on the history of chemistry, entitled Chymia. A volume will consist of about a dozen articles, each of about 4,000–5,000 words, contributed by outstanding scholars from all over the world. The publication is sponsored by the Edgar F. Smith Memorial Collection at the University of Pennsylvania, a well-known collection of rare books, manuscripts, prints, and other items of interest in the development of chemistry. Publication will be under the direction of a board of American editors with a group of consulting editors, all of international prominence. The first number is ready for the press and will probably be issued this autumn. The Oxford University Press will publish Chymia in Great Britain. Requests for further information should be addressed to Eva V. Armstrong, secretary of the Board of Editors, Edgar F. Smith Collection, Harrison Laboratory, University of Pennsylvania, Philadelphia 4.
