DR. G. A. H. BUTTLE has been appointed to the chair of pharmacology at the College of the Pharmaceutical Society, in succession to Prof. J. H. Gaddum, who now holds the chair of pharmacology at the University of Edinburgh. Prof. Buttle returns from a long and varied experience in the Army, in which he held the rank of lieut.-colonel, R.A.M.C. He served for six years as officer commanding Base Transfusion Unit and adviser in resuscitation with the Middle East Forces and later with the 21st Army Group. Previous to the War, in conjunction with Henry, Trevan and Stephenson, he published work on chemotherapeutics from the laboratories of the Wellcome Foundation, including much work on the antibacterial action of sulphanilamide and allied substances in strepto-coccal infections. In conjunction with Colebrook and O'Meara he demonstrated the inhibitory effects that sulphanilamide compounds had on bacteria outside the body. During the War, in conjunction with Lieut.-Colonel G. Mitchell, he published investigations on the treatment of infected war wounds with powder of sulphanilamide and derivatives of acridine, and several articles on blood transfusion for service purposes. As director of the Pharmacological Laboratories in the College of the Pharmaceutical Society, he will be able to continue the work of Burn and Gaddum on biological assays, and will undoubtedly be a great asset to the team of research workers already engaged on the chemical aspects of chemotherapy.
