Report submitted by Darlington to N.M.V. Rothschild and to the Agricultural Research Council, 1955-1956. The material is in part a development of Darlington's memorandum of 1953 (MS. Darlington c. 11/B.48) and in part an expansion of views he expressed in an article 'Government Sponsored Research in Britain' (Science and Freedom, Apr 1955). Rothschild took particular exception to Darlington's reference to 'the business interests of those controlling research in the Agricultural Research Council'.
