--The Camera Obscura was removed
from the N.W. Turret of the Great Room, to make way for the
Anemometer.--In Magnetism and Meteorology the most important thing was
the great magnetic storm of Sept. 29th, which revealed a new class of
magnetic phenomena. It was very well observed by Mr Glaisher, and I
immediately printed and circulated an account of it.--In April I
reported that the Planetary Reductions were completed, and furnished
estimates for the printing.--In August I applied for 18,000 copies of
the great skeleton form for computing Lunar Tabular Places, which were
granted.--I reported, as usual, on various Papers for the Royal
Society, and was still engaged on the Cavendish Experiment.--In the
University of London I attended the meeting of Dec. 8th, on the
reduction of Examiners' salaries, which were extravagant.--I furnished
Col. Colby with a plan of a new Sector, still used in the British
Survey.--I appealed to Colby about the injury to the cistern on the
Great Gable in Cumberland, by the pile raised for the Survey
Signal.--On Jan. 3rd occurred a most remarkable tidal disturbance: the
tide in the Thames was 5 feet too low. I endeavoured to trace it on
the coasts, and had a vast amount of correspondence: but it elicited
little.
