~T. First Comet of 1846; (L’Institut. No. 638, March 25, 1846. fon 
This comet was discovered Jan. 24, 1846, in the constellation Erida- 
% . nus, by the Astronomers at the Observatory of the College at Rome. 
Although its light was feeble, it showed occasionally a distinct nucleus, 
and a small fan-shaped tail. It was observed up to March 4th, and 
probably somewhat later. The following approximate elements of its 
bs orbit were obtained by the Roman Astronomers:

2. Second Comet of 1846.—The comet discovered February 26, 
1846, by Mr. George P. Bond, at the Observatory of Cambridge, Mass., 
an account of whose elements was given in this Journal, ii. Ser. i, 447, 
» had been previously diateniad on the 20th of that month, by the 
Astronomers at Rome. It was followed until about the 20th of May. 
lis orbit has much resemblance to that of the comet of 1707. 
3. Third Comet of 1846.—On the 26th of Feb., 1846, Mr. Brorsen 
at Kiel, in Holstein, discoyered a telescopic comet near 7 Piscium. 
Its parabolic €lements computed by Mr. Petersen of Altona, are given 
Mr. Schumacher, together with the elements of Apian’s 
low, b 
comet of 1532 referred to the ecliptic of 1846-0. Its elements agree 
also very nearly with those of the comet of 1661. ;
