"In July the new constant-service water-pipes to the Observatory were laid from Blackheath. Before this time the supply of water to the Observatory had been made by a pipe leading up from the lower part of the Park, and was not constant.--In May the new staircase from my dwelling-house to the Octagon Room was commenced.--In the Report to the Visitors there is a curious account of Mr Breen's (one of the Assistants) personal equation, which was found to be different in quantity for observations of the Moon and observations of the Stars.--The most important set of observations (of planets) was a series of measures of Saturn in four directions, at the time when his ring had disappeared. They appear completely to negative the idea that Saturn's form differs sensibly from an ellipsoid.--Among the General Remarks of the Report the following appears: 'Another change (in prospect) will depend on the use of galvanism; and as a probable instance of the application of this agent, I may mention that, although no positive step has hitherto been taken, I fully expect in no long time to make the going of all the clocks in the Observatory depend on one original regulator. The same means will probably be employed to increase the general utility of the Observatory, by the extensive dissemination throughout the kingdom of accurate time-signals, moved by an original clock at the Royal Observatory; and I have already entered into correspondence with the authorities of the South Eastern Railway (whose line of galvanic communication will shortly pass within nine furlongs of the Observatory) in reference to this subject.'--I agreed with Schumacher in giving no medal to Mr G. P. Bond; his comet was found to be Petersen's. Five medals were awarded for comets in 1847 (Hind, Colla, Mauvais, Brorsen, Schweizer).--The Liverpool Observatory was finished this year: and the thanks of the Town Council were presented to me.--Respecting Fallows's Observations at the Cape of Good Hope: I had received the Admiralty sanction for proceeding with calculations in 1846, and I employed computers as was convenient. On July 20th of this year I was ready with final results, and began to make enquiries about Fallows's personal history, and the early history of the Cape Observatory. On Oct. 23rd I applied for sanction for printing, which was given, and the work was soon finished off, in the Astronomical Society's Memoirs.--In the month of March I had commenced correspondence with various persons on the imperfect state of publication of the British Survey. Sheets of the Map were issued by scores, but not one of them had an indication of latitude or longitude engraved. I knew that great pains had been taken in giving to the principal triangulation a degree of accuracy never before reached, and in fixing the astronomical latitudes of many stations with unequalled precision. Finally I prepared for the Council of the Royal Society a very strong
