THE Royal Anthropological Institute has appointed a Mining and Metallurgical Committee to investigate problems 41 early metallurgy, as part of its scheme for group studies of the evolution of man. Among the fiit matters to be studied by the Committee is early use of copper. When found in its metallic form, the element is known as ‘native’ copper, and metal of this kind undoubtedly formed the earliest sources of copper supply. Samples from various parts of the world are being collected by the Committee and analysed with the object, if possible, of relating their particular composition to that of ancient specimens of copper work. The Committee includes the following: Mr. C. E. N. Bromehead (Geological Survey and Museum); Prof. V. Gordon Childe (Institute of Archaeology, London); Mr. H. H. Cogh-lan (chairman); Prof. C. H. Desch; Dr. Oliver Davies (Queen's University of Belfast); Mr. A. Digby (British Museum); Prof. C. F. C. Hawkes (University of Oxford); Dr. W. Lamb (secretary); Mr. T. K. Penniman (Pitt Rivers Museum, Oxford); Prof. Stuart Piggott (University of Edinburgh); Dr. H. J. Plenderleith (British Museum); Dr. J. Raftery (National Museum, Dublin); Mr. B. Webster Smith (Copper Development Association).
