Some Recent Services of Metallurgy to Engineering

IN honouring me with the invitation to deliver the James Forrest lecture this year—the thirty-third of the series—the Council of this Institution expressed a desire that I should deal with recent advances in metallurgy which have a bearing on engineering practice. It is twentyone years since my distinguished predecessor Sir Robert Hadfield delivered the last lecture in which metallurgy constituted the main subject, and it would seem convenient, therefore, that I should deal with the progress made since that date.
