"The Science of Life: a summary of contemporary knowledge about life and its possibilities" was first issued in 31 fortnightly parts published by Amalgamated Press in 1929–30, bound up in three volumes as publication proceeded. A mail-order version of the book was also published, though this was dropped after the stock market crash. It was first issued in one volume by Cassell in 1931, and reprinted in 1934 and 1937; a popular edition, fully revised, with a new preface by H. G. Wells, appeared in 1938. It was again published as separate volumes by Cassell in 1934–1937: I "The living body". II "Patterns of life" (1934). III "Evolution—fact and theory". IV "Reproduction, heredity and the development of sex". V "The history and adventure of life". VI "The drama of life". VII "How animals behave" (1937). VIII "Man's mind and behaviour". IX "Biology and the human race". In New York, it was published by Doubleday, Doran &amp; Co. in 1931, 1934 and 1939; and by The Literary Guild in 1934. Three of the Cassell spin-off books were also published by Doubleday in 1932: "Evolution, fact and theory"; "The human mind and the behaviour of Man"; "Reproduction, genetics and the development of sex". "The Science of Life" was translated into French. During World War II a one-volume edition designed for use in military classes was issued. As late as 1960 the work was still being used in college classes in the US
