Occultation of Regulus on April 6. Extensive preparations were made to observe this occultation at stations near the northern boundary, which crossed England from Liverpool to Dover. Both in the neighbourhood of Canterbury and in that of Hitchin, parties of astronomers occupied posts about a mile apart along lines at right angles to the boundary; but clouds prevented any useful results from being obtained. The only time-observation to hand was made by Rev. O. Walkey at St. Buryan, Cornwall; long. 5 ° 36′ 18″W., lat. 50 ° 4′ 58″N.; in a letter to the Morning Post he gave the time of disappearance as 20h35m23s U.T., but did not give the time of reappearance, though he stated that the star was hidden for 45m, which is the maximum for any point in the British Isles. The phenomenon was seen as a spectacle from Worthing, but no times were recorded. It is worth while to remind the public that they can do useful work by timing the disappearance of stars, using the wireless time-signals to find the errors and rates of their clocks. The times must be given to seconds, and the position of the station determined from a large-scale ordnance map.
