The collection comprises two volumes containing off-prints of published articles by Professor Challenger. The volumes were compiled by Professor Challenger in 1954 and primarily concern the period 1908-1954. Occasional later items include an article written in 1978. The papers for the most part look at the preparation, derivatives, interaction and substitution of various organic chemical compounds. Exceptions include 'Frederic Stanley Kipping 1863-1949' (1951), 'The Chemistry Department of the University of Leeds' (1953), and an obituary of Andrew Jamieson Walker (1873-1935) (MS 740/1);
Challenger's research into the work of Professor F.S. Kipping is recorded in correspondence and photocopied papers, 1951-1975 (MS 740/2).
