Abstract
THE RING NEBULA IN LYRA.—Prof. Holden reports that this object, as seen with the great Lick refractor, shows far more detail than had been detected either by Lassell with his 4-foot reflector, or by the Washington observers with the great 26-inch refractor. With these telescopes thirteen stars had been seen in an oval outside the ring, and one star had been seen within it. The 36-inch Lick telescope shows twelve stars within the ring or projected upon it, and renders it obvious that the nebula consists of a series of ovals or ellipses: first the ring of stars, then the outer and inner edges of the nebulosity, next a ring of faint stars round the edges of the inner ring, and last a number of stars situated on the various parts of the nebulosity and outer oval.
