Of the scientific papers read before the British Association, those
dealing with radium were of the greatest interest. Mr. Boys, the president of the Mathematical and Physical Science Section, in his review of the events of the year described tha properties of radium as transcending all others in their intrinsic importance and revolutionary possibilities. Even more striking was the conclusion of Professor Schuster's paper. We had passed, he said, through fifty years in which the most prominent features of advance were connected with conservation of energy, conservation of matter, and conserva- tion of electricity. " Perhaps we should now pass through fifty years in which the most prominent features would be dissipa- tion of energy, dissipation of matter, and dissipation of elec- tricity." On Sir Robert Giffen's paper we comment elsewhere, but may note, among other papers of practical interest, those on the Garden City Movement read before the Economic Science Section. It is interesting to learn that a site of four thousand acres in the neighbourhood of Hitchin will be in the possession of the Garden City Company by Michaelmas.
