Abstract
DR. HUGHES' S recent remarks1 would appear to be based on the three wrong premises that, first, films of soft metals wiped on to steel surfaces on which a loaded steel ball was made to rotate2 never decreased the electromotive force ; secondly, the interpretation of earlier observations3 on the frictional behaviour of such films on a copper surface made on the Bowden-Leben apparatus had been criticized; and thirdly, frictional decreases due to these films should be taken as an indication that changes in the ploughing contribution to the frictional force were immaterial when such decreases were observed “during the first slide” with the Bowden-Leben apparatus.
