ides beingattended by no less than seven moons, is surroundedwith two broad, flat, rings, extremely thin, andnearly concentric with the planet. They lie in the same plane, and are separated from eachother by a very narrow interval. That which separates theinner ring from the body of the planet is much wider. Thethickness of this extraordinary appendage, according to theyounger Herschel, does not exceed 100 miles. The otherdimensions, as derived from the observations of Struve, areas follows: Exterior diameter of exterior ring 176,418 miles. Interior diameter of exterior ring 155,272 Exterior diameter of interior ring 151,690 Interior diameter of interior ring 117,339 Equatorial diameter of the body 79,160 Interval between the planet and interior ring 19,090 Interval between the rings .... ; 1,791 A telescopic view of Saturn is given in thefrontispiece. It is surrounded by its rings, andits body is striped with dark parallel belts resem-bling those of Jupiter, but less strongly marked,

Thatthe ring is a solid opaque substance, is evidentfrom the fact that it casts a shadow upon the sideof the planet nearest the sun, and on the oppositeside the ring receives the shadow cast by the bodyof the planet, as represented in the figure. Fromthe parallelism of the belts with the plane of thering, it might be conjectured that the axis aboutwhich the planet revolves is perpendicular to thatplane; this is found to be the case by observa-tions of spots which are occasionally seen uponits surface, the motions of which indicate a rota-tion about such an axis in lOh. 29m. 17s., accord-ing to Herschel; this period is, however, some-what uncertain. The axis of Saturn, like that of the earth, pre-serves its parallelism to itself during the revolu-tion of the planet round the sun. (See the draw-ing.) The rings rotate about the planet, in theplane of its equator, in nearly the same time asis occupied by the planet in
