Mr. Ellis:—“The light of the planet, by contrast with the Moon, was very faint.” Mr. Carpenter:—“There was not the least alteration in the planet’s form.” Capt. Noble:—“Saturn appeared of a richly-greenish yellow when compared with the brilliant white light of the Moon.” Mr. G. C. Talmage:—“The difference in colour between Saturn and the Moon was most marked, the planet appearing of a yellow tint.” Mr. J. Carpenter:—“At disappearance the planet was a very dull object when in contact with the Moon; its light probably a twentieth as bright. At reappearance the planet was rather tremulous; no distortion was noticed.” On June 13, 1870, the Rev. J. Spear, of Bengal, watched the Moon pass “steadily over the planet without causing any change of form or giving any indication of the planet’s light passing through an atmospheric medium. When near the Moon’s limb Saturn assumed a sickly green hue.” I observed the occultation of Sept. 30, 1870, at Bristol, with a 4-1/4-inch refractor; but the event offered no novel traits, the most prominent feature being the difference of brightness in the Moon and Saturn. Mr. C. L. Prince observed this event with a Tulley refractor of 6·8 inches aperture, power 250. He says there was not the slightest distortion of either body, but he noticed that “the edge of the ring lingered somewhat upon the Moon’s limb about the time of disappearance.” Another occultation occurred soon after new Moon on April 9, 1883, and one of the observers, Mr. Loomis, described the disappearance of the rings as a spectacle of great interest, and said the impression was forcibly conveyed to his mind that the Moon was very much nearer to the eye than Saturn. _The Satellites._—The discovery of the eight moons of this planet ranged over the long period of 193 years. Five different observers share the honours between them. Our knowledge of the Saturnian satellites may almost be said to furnish us with a history of improvements in the telescope; for they were severally detected at epochs corresponding to instrumental advances. The following are the periods, distances, &c. of the satellites:—
