Royal Observatory Greenwich - GA has just returned from observing lighthouses in France. He cannot tell WW everything about the Board of Visitors meeting since both GA and Adams [John C. Adams] were not informed that the meeting was to be an hour early: 'So I found Lubbock [John W. Lubbock] in full speech, very absurdly as I thought, in the same strain as his printed papers. I endeavoured to explain in reply that there was no notion of preferring numerical to algebraical expressions &c'. A vote was taken before GA left early for his train to Dover. Sir James South was there protesting against any recommendation of grant to any body for any thing. Hansen [Peter Andreas Hansen] has theoretically investigated the variation and evection, and concluded that these rays do not agree perfectly with those observed because of the figure of the moon - 'this is the whole that Lubbock means by empirical'.
