Thursday May 10, 1894

Mr Hughes from Director of Stores Departt made out his list of Office furniture required for new building South Wing. Mr Simms Junr commenced mounting Simms & Cooke Equatorials & Water Telescope in South Wing Basement. Mr McGilicuddy[?] from Doching[?] & Son called about a mistake in no of copies of Astr. Results 1891, the 180 separate copies not having been struck off. I complained to him of the slow rate of printing. Settled [illegible] details of mounting of Spectroscope on 28 inch telescope. Went to meeting of R.S. (Papers on Eclipse of 1893 April 16) & to dinner of R.S. Club.

RH says..... E.Walter Maunder had this to say about the Water Telescope:
"An ingenious telescope was set up by Sir George Airy in order to ascertain if the speed of light were different when passing through water than when passing through air. Or, in other words, if the aberration of light would give the same value as at present if we observed through water. The water telescope, as it was called, is kept on the ground floor of the central octagon of the new observatory. The observations obtained with it were hardly quite satisfactory, but gave on the whole a negative result."
The Royal Society Club was a dining club, for the inner circles of the Royal Society. See Archibald Geikie's 1917 Annals of the Royal Society Club; the record of a London dining-club in the eighteenth & nineteenth centuries for background.
