8vo: 10 pp. Three figures. Lightly aged, but good. In original green printed wraps. Two punch holes to inner margin. 'With the compliments of the authors' by Ellis on front wrap. Ellis was co-author, with Rutherford and Chadwick, of 'Radiations from Radioactive Substances' (CUP, 1930), a work said by A. R. Mackintosh ('The Third Man: Charles Drummond Ellis, 1895-1980', Notes and Records of the Royal Society of London, July, 1995) to have been 'often referred to as the "Bible" of nuclear physics', with Ellis's contribution to the work placing him 'third among equals'. Mackintosh argues that Ellis's 'achievements were very great', and that he was 'among the most accomplished and important experimental physicists of the century'. He is said by Mott to have 'practically discovered the neutrino'. For further details see his entry in the New DNB.
