Admiralty, I believe) in favour of procuring for the Cape Observatory a Transit Circle similar to that at Greenwich.—­I had much correspondence about sending Pierce Morton (formerly a pupil of mine at Cambridge, a clever gentlemanly man, and a high wrangler, but somewhat flighty) as Magnetic Assistant to the Cape Observatory:  he was with me from May to October, and arrived at the Cape on Nov. 27th.—­I was much engaged with the clock with conical motion of pendulum, for uniform movement of the Chronographic Barrel.—­Regarding galvanic communications:  On Sept. 19th I had prepared a Draft of Agreement with the South Eastern Railway Company, to which they agreed.  In November I wrote to Sir T. Baring (First Lord of the Admiralty) and to the Admiralty for sanction, which was given on Dec. 18th.  In December I had various communications about laying wires through the Park, &c., &c., and correspondence about the possibility of using sympathetic clocks:  in June, apparently, I had seen Shepherd’s sympathetic clock at the Great Exhibition, and had seen the system of sympathetic clocks at Pawson’s, St Paul’s Churchyard.—­In the last quarter of this year I was engaged in a series of calculations of chronological eclipses.  On Sept. 30th Mr Bosanquet wrote to me about the Eclipse of Thales, and I urged on the computations related to it, through Mr Breen.  In October the eclipse of Agathocles (the critical eclipse for the motion of the Moon’s node) was going on.  In October Hansteen referred me to the darkness at Stiklastad.—­I went to Sweden to observe the total eclipse of July 28th, having received assistance from the Admiralty for the journeys of myself, Mr Dunkin, Mr Humphreys and his friend, and Capt.  Blackwood.  I had prepared a map of its track, in which an important error of the Berliner Jahrbuch (arising from neglect of the earth’s oblateness) was corrected.  I gave a lecture at the Royal Institution, in preparation for the eclipse, and drew up suggestions for observations, and I prepared a scheme of observations for Greenwich, but the weather was bad.  The official account of the Observations of the Eclipse, with diagrams and conclusions, is given in full in a paper published in the Royal Astr.  Society’s Memoirs.—­This year I was President of the British Association, at the Ipswich Meeting:  it necessarily produced a great deal of business.  I lectured one evening on the coming eclipse.  Prince Albert was present, as guest of Sir William Middleton:  I was engaged to meet him at dinner, but when I found that the dinner day was one of the principal soiree days, I broke off the engagement.—­On May 26th I had the first letter from E. Hamilton (whom I had known at Cambridge) regarding the selection of professors for the University of Sydney.  Herschel, Maldon, and H. Denison were named as my coadjutors.  Plenty of work was done, but it was not finished till 1852.—­In connection with the clock for Westminster Palace, in February there were considerations about providing
