Astronomical Discovery.

In an article in the March number of the Atlantic Monthly entitled "Venus in the Light of Recent Discoveries," Perceval Lowell of the class of '70 publishes a discovery he has recently made, that Venus rotates on her own axis only once a year, thus keeping one hemisphere continually toward the sun, and the other hemisphere in perpetual night. Hitherto it has been supposed that Venus rotated more than once a year, though the exact length of her day was a matter of dispute.
