    COMET 1909a, BORRELLY-DANIEL.—Further observations of comet 1909a have revealed no striking features either in its form or in its behaviour. In No. 4334 of the Astronomische Nachrichten M. Chofardet records the observations made at the Besanon Observatory, and states that on June 17 and 19 the comet was of magnitude 11.0 or 12.0, had a round, diffused head of 1.5′ diameter, and a vague condensation which could be seen occasionally by oblique vision.
