BY PROF. MARIA MITCHELL. To the eye, Saturn is far less conspicuons than is farther from us, it is smaller, its color less might easily be taken for one of the countless stars. The first look at it, with a telescope, is an unexpecteddelight. 57 106 SATURN. Like Jupiter, it lias its moons ; like Jupiter it has bands-crossing its disc, nearly parallel to its equator; unlikeevery other planet, it is surrounded by a ring, usually soinclined that it stands out in front of the ball of theplanet. It is a broad, flat ring ; perhaps we might call. it a bottomless placque. At times, when the edge of thering is presented to the sun, or, when the plane of thering passes through the centre of the earth, it appears asa line across the ball, a line so narrow, that it can be seenonly by large telescopes. The thickness of the ring issupposed by some observersto be one hundred miles, byothers to be only forty powerful glasses, thering is seen to be made up of several rings. When theserings are tipped obliquely to the plane of Saturns equa-tor, dark open spaces are seen between the ball and thering ; these are supposed to be the sky ; dark curvedlines upon the plane of the rings are supposed to be- 58
