Abstract
THE seventh International Congress of Mining, Metallurgy and Applied Geology was opened at the Sorbonne, Paris, on October 20, and will continue until October 26. The President of the Republic, M. Lebrun, was present at the inaugural session. Sir Robert Hadfield, the delegate of the Iron and Steel Institute, presented to M. Lebrun a copy of the picture in the Bodleian Library, Oxford, depicting Roger Bacon presenting a book to the Chancellor of the University of Paris. Sir Robert also presented a miniature knife of steel made by Michael Faraday during the years 1819–24 while he was residing at the Royal Institution. The steel contains 0.74 per cent platinum. The weight of the blade is one-hundredth of an ounce, and that of the complete knife, one-twentieth of an ounce. Sir Robert suggested that the knife should be handed either to Dr. Leon Guillet, head of the Ecole Centrale des Arts et Manufactures, or to the Ecole des Mines.
