Referee's report by Edward Mellanby, on a paper 'Appetite and choice of diet. The ability of the vitamin B deficient rat to discriminate between diets containing and lacking the vitamin' by Leslie J Harris, Janet Clay, J Hargreaves and Alfred Ward Sectional committee: Physiology Recommended for publication in Proceedings, in full. The summary and conclusion should be shortened. The word 'Bovril' should be replaced with 'meat extract', as some meat extracts now contain yeast. 'Marmite' should also be changed to 'yeast extract'. Some of the figured should be omitted. [Published in Proceedings of the Royal Society B, 1933]. Endorsed on verso as received 25 November 1932. November 1932
