CHARGE OF THE CAMBRIDGE OBSERVATORY
TO HIS
RESIDENCE AT GREENWICH OBSERVATORY AS ASTRONOMER
ROYAL.
FROM MARCH 15TH 1828 TO JAN. 1ST 1836.
1828
“I attended a meeting of the Board of Longitude on Apr. 3rd. And again on June 4th; this was the last meeting: Sheepshanks had previously given me private information of the certainty of its dissolution.—On Apr. 4th I visited Mr Herschel at Slough, where one evening I saw Saturn with his 20-foot telescope, the best view of it that I have ever had.—In June I attended the Greenwich Observatory Visitation.—Before my election (as Plumian Professor) there are various schemes on my quires for computation of transit corrections, &c. After Apr. 15th there are corrections for deficient wires, inequality of pivots, &c. And I began a book of proposed regulations for observations. In this are plans for groups of stars for R.A. (the Transit Instrument being the only one finished): order of preference of classes of observations: no reductions to be made after dinner, or on Sunday: no loose papers: observations to be stopped if reductions are two months in arrear: stars selected for parallax.—The reduction of transits begins on Apr. 15th. On May 15th Mr Pond sent me some moon-transits to aid in determining my longitude.—Dr Young, in a letter to me of May 7th, enquires whether I will accept a free admission to the Royal Society, which I declined. On May 9th I was elected to the Astronomical Society.—Towards the end of the year I observed Encke’s Comet: and determined the latitude of the Observatory with Sheepshanks’s repeating circle.—On my papers I find a sketch of an Article on the Figure of the Earth for the Encyclopaedia Metropolitana.
