ABSTRACT
The author first met Rutherford in 1913, when he was appointed John Harling Fellow in succession to Moseley, to follow whom was a distinction not so clear at the time as it is now. Likewise at the Manchester colloquium, which met on Friday afternoons, Rutherford was, as in all his relations with the research workers, the boisterous, enthusiastic, inspiring friend. William Kay, the head laboratory steward, was an extraordinary man. Always busy, he was always good-tempered and willing to help. He made, in his spare time, a large number of drawings for Rutherford's Radioactive Substances and their Radiations. The author's apparatus for the work on the wave length of gamma rays included a large magnet for deflecting the beta particles out of the way. As Nature said of it 'That it should come from the laboratory of Prof. Rutherford and have for its authors two such distinguished workers on radioactivity, practically ensures its general adoption in advanced physical laboratories'.
