Stuk 78 - Letter from George Airy

4 pp.

Royal Observatory Greenwich - GA has been presented with a great correspondence on the observation of tides, involving at least twelve stations selected between Aden and Cape Comorin: 'But how long observations were to be made, at what periods of year, with what meteorological observations these were to be connected, how long and under what regulations the latter were to be made, I cannot make out'. GA thinks 'the indication of the nature of the observations' came from WW - 'if you could rake up any recollection of the proposed plan...I should be glad to have it. It is partly necessary to guide me in answers respecting the choice and expense of instruments'.
