Letter from John Roscoe, Orvington Rectory, Thetford, to Robert Harrison, Assistant Secretary of the Royal Society Notes that no notice has come regarding the change of the meeting time, so arranges to come up on Monday and hopes that it is at 2.30pm. Apologises for the trouble over the license for exporting goods - notes that the Army & Navy Stores told him it was only necessary to get a license for tea and sugar as other goods might go freely, hence his mistake. 28 March 1919
