The influence of Rutherford and the Cavendish laboratory at Cam-
bridge in relation to atomic research is continuously pervasive. Dr. W. B. Lewis, who has just been appointed Director of Scientific Research at the Canadian atomic energy plant at Deep River, Ontario, is another of Rutherford's men. He is still only 38 and since 193o has been in the centre of Nuclear Physics research at Cam- bridge. Whether in the end it will prove to be more good than ill that has emanated from the Cavendish in this field still remains to be demonstrated. But the volume of the emanation is immense.
