That the dusky ring is not transparent throughout, contrary to all the observations made hitherto; and that it grows more dense as it recedes from the planet; so that, at about the middle-of its width, the limb of the planet ceases entirely to be seen through it. "8. And, finally, that the matter composing the dusky ring is agglomerated here and there into small masses, which almost totally prevent the light of the planet from reaching the eye of the observer."

Mr. Todd has employed his new 8-inch eqnatoreal, by Cooke, mounted in December 1874, in making a very valuable series of observations of the phenomena of Jupiter's satellites during the last opposition of the planet, extending from June 13 to October 15, 1876. He has recently forwarded to the Astronomer-Royal, for communication to the Society, a detailed statement of these observations, which consist of eclipses, occultations, and transits of the satellites, and also of the ingress and egress of the shadows. The local mean times of observation are given, as well as the corresponding Greenwich mean times, which are compared with the calculated times in the Nautical Almanac.
