" November 15th, 1^ 30^. Examined the new ring of Saturn with 

 different powers, best definition with 400. New ring sharply defined ; 

 edge next the ball. VV. C. Bond thinks he sees the new ring clear of 

 connection with the old, but the side next the old ring is not so definite 

 as next the planet, so that it is not certain whether the new is connected 

 with the old ring or not* Where the dusky ring crosses Saturn^ it ap- 

 pears a little wider at the outside of the ball than in the middle. Where 

 the new ring crosses Saturn^ it appears not so dark as the shadow of 

 the ring below on the body of the planet.^' 



^'8 F. M. The best definition of Salurn'^s ring we have ever had. 

 G, P. Bond examined with powers 140 and 400. Cannot be sure that 

 the new ring is divided from the old one, but there can be' no doubt 

 that it exists ; its inner edge is sharply defined. I did once or twice 

 fancy, with the higher powers, that there was a division between the 

 old and new rings. All the southern region of Saturn is dusky and 

 striped with belts. 



Outer diameter of outer ring, . . . =:43'^'9 



Inner diameter of inner ring, i . . =29 "3 



Breadth of outer ring, . ♦ . . z=: 2 '3 



Inner diameter of dusky ring, . . , z=:26 "3 



Distance of its inner edge from old ring, . i=: 1 '5 



"According to Encke's measures, Aslr. NacL, No. 338, the inner 

 diameter of the inner ring should be, at the above date, about 29''*8; 

 whereas, by the above measures, we make the inner diameter of the 

 new ring to be only 26"'3." 



Our observations, continued to the 7th of January, fully confirmed 

 the deductions which we had drawn from those of the 11th and 15th 

 of November.

The same appearances were noticed by the Rev. W. R. Dawes, at 

 his Observatory, near Maidstone, in England, on the 25ih and 29lh of 

 November, and subsequetitly by Mr. Lassell, of Starfield, near Liver- 

 pool, An account of their observations is given in the Royal Astro- 

 nomical Society's Notices for January lOih, 1851. 



2. On the Total Eclipse of the Sun, of July 28, 1851 ; by R. T- 

 Paine, Esq. — Ahhough there will be*many inducements for travellers 

 from the United Stales to visit Europe this summer, it is believed there 

 is no one stronger than the total eclipse of the Sun which will lake 

 place on Monday, the 2Sth of July, and which being visible over a 

 great extent of the surface of the Earth, will be one of the most im- 

 portant that will happen for many years. 



On this occasion a total or partial obscuration of the Sun may be 

 seen throughout the greater part of North America, (Mexico and the 

 southern extremity of Florida being excepted,) throughout Europe, in 



the western, northern, and northeastern parts of Asia, in the northern 

 and northwestern parts of Africa, in Greenland, &c., whilst the line of 

 the central and total eclipse will pass over 191 degrees of longitude, or 

 from the vicinity of Sitka, the capital of the Russian settlements on 

 our northwest coast, to the southeastern extremity of the Caspian sea. 



But in no part of the United Slates will the eclipse be total; the 

 greatest obscuraiioa within our territory taking place at Cape Flattery,
