Each of them noticed a flattening of the north-polar regions of the planet in the summer of 1848, when the ring was turned edgewise toward us. On the other hand, the same observers noticed that in 1855-57, when the ring was most widely opened, the polar regions did not always seem projected furthest on the outer ring in a symmetrical manner, but four times on the left of the pole, once on the right, and once only, exactly opposite the pole. "The outline of this region also occasionally appeared irregularly flattened and distorted," an appearance not satisfactorily explained by the juxtaposition of the dark shadow of the planet on the ring. Now, there can be no doubt whatever that the planet Saturn is not ordinarily distorted. In 1832, during the disappearance of the ring, Bessel carefully determined the figure of the planet's disk, and Main in 1818 (when the ring was again turned edgewise toward us) made similar measurements. Each of these trustworthy authorities came to the conclusion that the disk of Saturn did not, at the seasons when they respectively measured it, exhibit any distortion of figure such as Herschel had described. We seem almost compelled, therefore, to accept the conclusion that the planet Saturn is subject to the influence of forces wjiich either upheave portions of its surface from time to time, or cause vast masses of cloud to rise to an enormous height above the mean layer of Saturn's cloud-envelope. Whichever view we adopt, we cannot fail to recognize the fact that an intense heat must in all probability prevail in the great globe of Saturn; and doubtless the real mass of the planet must emit a brilliant light, though the cloud-strata surrounding him may prevent us from'recognizing...
