Abstract
Comets.—A photograph of Skjellerup's Comet, 1922b, was obtained on July 31 at Greenwich: it confirms the short period, which appears to be very close to 5 years, thus making it definitely the second shortest cometary period. That of Encke's Comet is 31/3years, that of Tempel's Second Comet is 51/6; years. The identity with Grigg's Comet, 1902 II, is rendered almost certain, since both the period and the other elements accord closely. The perihelion distance has increased considerably, but only by an amount comparable with that which has occurred in the case of the Comet Pons-Winnecke.
