Letter from William B Hardy, Department of Scientific and Industrial Research, 16 Old Queen Street, Westminster, to Henry Dale Has had a talk with [A W] Flux, statistician at the Board of Trade, about bringing the food supply survey up to date, perhaps to include change in caloric values and introduction of vitamin content. Suggests that a small committee be got together to advise Flux. Thinks that the Society might publish a new edition of its own report. 21 March 1927
