4lh of July was by computation only nine millions of miles. The follow- 

 ing elements have been computed from observations of JuljS, 13, and 23d.

 6. Comet II, 1862.— The discovery of this comet, July 18th, at the 

 Dudley Observatory, was mentioned in the last number of this Journal, 

 p. 294. On the same evening this comet was discovered at the Cam- 

 bridge Observatory by H. P. tuttle. On the 22d of July it was discov- 

 ered at Florence; on the 25th it was discovered at Rome; and on the 

 26th it was discovered independently at Copenhagen. 



The following elements have been computed from observations of 

 July 24, 31, and Aug. 6th.

 On the 15th of August this comet attained a north declination of 82°, 

 d for five weeks from its first discovery, it remained within the circle of

 ""^ t^^MnlL.nn of Omkron Ceti.—Th^ brightness of Omicron Ceti was 

 J;m:ZZ:nZr^^^ pasts»mmerbyM. Schmidt at Athens, 

 and the'time of its max^num fixed at July 2d It was then ^I'g^t 7 

 fainter than Alnha Ceti. As the period of this star is 332 days, the next 

 irxTmumwm occur May 30, 1863, which probably however cannot be 

 observed on account of proximity to the sun.
