Lowry participated in 2 magazines whilst at Cambridge - Venture and Experiment. He had 2 short stories published by Experiment - 'Port Swettenham', pp. 22 - 26 No 5 and 'Punctum Indifferens Skibet Gaar Videre', pp. 62-75 No 7.
The magazine was edited by William Empson, Jacob Bronowski, Hugh Sykes and Humphrey Jennings, published in Cambridge from November 1928 - Spring 1931. The publisher for: Nos. 1-2 was Cambridge University Press; Nos. 4-7 were published by G. F. Noxon, Trinity College, Cambridge/G. F. Noxton, 68a St. Andrew's Street, Cambridge. There were only seven editions which came out on a Quarterly-Irregular basis priced one Shilling and sixpence. Read more about edition on Modernist Magazine Project.
