Guy's Elements of astronomy : and an abridgment of Keith's New treastise on the use of the globes . I Yertfu o 8 Me/*rt/7\ o Q Eizrffi \ jSr jifoo/f stn. ^ Jff/?fAu Saturns ring. 21 planet in 22 hours and a half; and that which is most remote takes 79 days 7 hours. The last Sfiiellife is known to turn on its axis, and in ts rotation lo>e subject to the same law whirh our moon obeys; that is, it revolvesin its axis in the same time in which it revolves about the planet Saturns Ring. Saturn is also encompassed with a kind of Ring^^or, according to Dr. Herschel, with two concentricrings, situated in one plane, which is not much inclin*ed to the equator of the planet. They may probably beof considerable use in reflecting the light of the sun tohim. See plate. From numerous observations it has been concluded, that the nearest is 21,(j00 miles distant from Saturn, and that the breadth of the innernng is 20,000 miles; that of the outer ring7,2C0 miles; and the vacantgjiace between the two rings 2,839 miles. Dr. Herschel conjectures that it is no less solid than the planet itself;and he has found that it casts a strong shadow upon the plane
