Abstract
THE PLANET MEBCUEY.—Revue, Scientifique of Aug. 11 contains an illustrated article on this subject by M. L. Rudaux, who has been observing the planet at intervals since 1893 at his observatory at Douville. His aperture of 4 inches is rather small for this purpose, but he enjoys a good atmosphere, and several of the sketches reproduced show a considerable amount of detail. His chart of the planet resembles in many of its features that published a year ago by M. E. M. Antoniadi from his studies with the great Meudon refractor. Both charts show the dusky regions much broader than the narrow streaks in. Schiaparelli's chart; for some markings all three charts agree, so these can be accepted with much confidence.
