Abstract
A CHART OF MERCURY.—M. E. M. Antoniadi published a chart of Mercury in Comptes rendus of the Paris Academy of Sciences in the autumn of 1927. This is reproduced, with a few additions resulting from his 1928 observations, with the 33-inch Meudon refractor, in the B.A.A. Journal for January 1929. Some of the markings, in particular those in the northeast quadrant, closely resemble those in Schiaparelli's chart, reproduced in Ast. Nach., 2944; but the southwest quadrant is practically filled with a dusky shading; the darker regions of this coincide with narrow dark markings drawn by Schiaparelli.
