The Leonid Meteor Shower.—Mr. W. F. Denning writes that “The nights of November 13 and 15 were alone suitable for observation at the period of the Leonid display this year, and very few meteors appeared. Mr. J. P. M. Prentice watched the heavens on the night of November 15 between 5.45 and 12.45 and recorded only 44 meteors during the seven hours, of which three were Leonids. At Bristol the sky was watched at a later hour, but only one Leonid was seen between 13h and 13h 45m, after which observations were discontinued. Mr. Prentice noticed several minor showers of which radiant points at 41°+29°, 42°+2i°, 53°+13°, and 55°+84° were the most actively pronounced.” The shower of Leonids was not expected to be abundant this year, as the parent comet (1866 I) will not return until 1933. It sometimes happens, however, that a moderately active display of Leonids occurs when the comet is far removed from perihelion, as in 1879 and 1888.
