THE Right Hon. J. Ramsay MacDonald has recently accepted an invitation to join the executive of the Parliamentary Science Committee. It has always been the aim of the Committee to preserve an even balance between men of science and Parliamentarians on the executive, and on the Parliamentary side to secure representatives from all political parties. Mr. MacDonald's advent brings the Parliamentarians up to eleven—three peers, and eight members of the House of Commons. The three peers are the Earl of Dudley (president), Lord Melchett and Lord Rothschild. The members of the lower house are Sir Arnold Wilson (chairman), Mr. Alan Chorlton (deputy-chairman), Mr. Ramsay MacDonald, Prof. J. Graham Kerr, Sir Philip Dawson, Sir Murdoch MacDonald, Mr. Andrew MacLaren, and Mr. S. F. Markham.
