THE object of the Bureau of Human Heredity, which has recently been founded (see NATUBE, 137, 795; 1937), is collection on as wide a scale as possible of material dealing with human genetics. Later, the tasks of analysis of material and distribution of the information available will be added. It is affiliated to the International Human Heredity Committee, which ensures co-operation in all areas where research is proceeding. The Council would be grateful to receive all available material from institutions and individuals, furnishing well-authenticated data on the transmission of human traits whatever these may be. Pedigrees are particularly desired; twin studies and statistical researches are also relevant. Announcements in regard to the services undertaken by the Bureau will be published from time to time. The address of the Bureau is 115 Gower Street, London, W.C.1.
