Copy letter from Robert William Frederick Harrison, to Rudolf Gustav Karl Lempfert, Meteorological Office, 63 Victoria Street, S.W. Harrison, in response to Lempfert's enquiry on behalf of Dr Van Rijckevorsel, states that he is not aware of the Royal Society possessing a publication entitled 'Meteorological Observations...1774-1883'. Such observations made by the Assistant Secretary were published annually at the end of Philosophical Transactions of the Royal Society between 1825 and 1843, but they cannot trace any other publication of these observations. 2 May 1906
