Abstract
THE ROTATION OF SATURN ON HIS AXIS.—On December 7 Prof. Hall, of the Naval Observatory at Washington, observed a very white spot on the disc of Saturn, just below the ring. At 6h. 18m., Washington mean time, the spot was central, and it was watched from 22h. 40m. sidereal time, to oh. 10m., as it moved across the disc. It was small, very well defined, and from 2″to 3″in diameter. A rough ephemeris of its motion was sent to various observers in the U. S., and the observations which have been received are as below. The second column gives the time when the spot was central.
