ORGANIC NOMENCLATURE RULES The Organic Division and the Nomenclature, Spelling and Pronunciation Committee of the American Chemical Society have distributed many copies of Austin M. Patterson's Translation with Comments of the Definitive Report of the Commission on the Reform of the Nomenclature of Organic Chemistry. The supply of reprints was exhausted some time ago but since strong demand for copies has continued arrangement has been made for planographic reprinting. The Organic Division and the Nomen-
clature Committee have cooperated in this undertaking. The new reprints have the advantage over the old ones of including the latest text adopted tentatively at Lucerne in 1936 and confirmed with dight modifications at Rome in 1938 of (1) the rule for the nomenclature of the derivatives of phosphorus, arsenic, antimony and bismuth and (2) the rule for the nomenclature of cyclic derivatives having side chains. The new reprints also contain an index prepared hy Doctor Patterson. Copies of the up-to-date report can be obtained by sending ten cents to the Chairman of the Nomenclature Committee, E. J. Crane, The Ohio State University, Columbus, Ohio.
