SJOGREN has reported that there is an annular negative gravity anomaly surrounding a small positive anomaly over the central basin of Mare Orientale (paper given at the NATO Advanced Study Institute on the Moon and Planets, Newcastle, April 1970). I should like to point out that outside this negative ring, there is a positive ring and perhaps further alternating rings. This outer positive ring contains as much apparent surface mass as the inner negative ring. The integrated mass anomaly associated with the Orientale region is very nearly equal to the central positive anomaly.
