Abstract
THE APRIL METEORS.—These meteors are due on April 20 or 21, but the moon, being full on April 23, ‘will be a bright object at the time and obscure small meteors. However, the shower occasionally ex hibits brilliant objects, so that it may be well worth looking for though the character of its display this year cannot be definitely foretold. The period of revolution of its supposed parent comet was com puted to be more than 400 years, but rich showers of Lyrids were witnessed in 1803, 1851, 1863, and other years, so that a short period apparently corresponds with some of the most abundant returns of the meteors. It is important to note the strength of the annual displays, so that the time of revolution of its more active returns may be determined. Its radiant is at 271°+ 33° on the night of maximum, but the centre of radiation travels eastwards one degree per day.
