MR. G. RADFORD MATHER, to whom the British Association owes the foundation of the Radford Mather lecture, is a retired engineer, now living at Wellingborough. Mr. Mather, who combines wide scientific knowledge with a deep*appreciation of the necessity for social service, has many and varied interests. He has given special attention to the study of those forces which govern minimal surface relations, and it was during a correspondence dealing with such matters that the attention of Mr. Mather was directed to the increasing interest shown by the British Association in the repercussions of advances in scientific knowledge on the well-being of the community. Mr. Mather has endowed a triennial lecture, to be given in London or the provinces, to be called the Radford Mather lecture, and to deal, for the most part, with the social implications of the advancement of science. Mr. Ramsay MacDonald gave the first lecture of the foundation, and portions of his address appear elsewhere in this issue. The scientific world is much indebted to Mr. Radford Mather for this foundation, and it is a matter for regret that, in view of his great age—he celebrated the ninety-sixth anniversary of his birthday on October 17—he was unable to be present at Mr. MacDonald's address.
