952 Catalogue of Celestial Objects [May, 
VII.—Catalogue of the most remarkable Celestial Objects visible in the 
horizon of Calcutta, arranged in order of Right Ascension. 
We have obtained permission to give publicity to the following ca- 
talogue, which was drawn up by Sir J. S. W. HerscHe tt, to accompany 
the ten feet reflecting telescope sent out to India by that distinguished 
astronomer for the private use of his relations in this country. Tt will 
of course answer equally well for other telescopes, and will in some 
measure serve as a test of their goodness and space-penetrating power. 
The names and numbers in the last two columns refer to Bopr’s 
maps of the constellations, which afford a ready means of finding the 
place of the object in the heavens, as they represent the stars of the 
celestial sphere direct, whereas upon the globe they are necessarily 
reversed. But to those who do not possess Bopr’s maps, the right 
ascension and declination will, with a little more trouble, enable the 
common observer to discover their position, while the astronomer with 
his transit will find out the whole with ease*. 
Explanation of the signs used in the Catalogue. 
Column 1, contains an enumeration of the whole. One asterisk (*) placed against 
a number denotes that the object is striking ; two asterisks (**) that it is 
particularly curious. 
Column 2, contains the right ascension in hours, minutes, and seconds. 
Column 3, the declination in degrees and minutes. 
Column 4, N and S, indicate whether the declination is north or south. 
Column 5, gives the authority whence the objects are extracted. The Roman numbers 
‘LIL IIE.’ &c. refer to Sir W. HeRScHELL’s catalogue of nebule and double 
stars by classes. 
A refers to Duntop’s catalogue of southern nebule. 
A’ ditto to ditto, double stars. 
M ditto to Messier’s nebule. 
Column 6, describes the object by the following signs. 
N, nebula. 
D, double. 
@, globular cluster. 
O, planetary nebulz. 
&, cluster of irregular figure. 
©, nebulous star. 
Column 9, refers to the numbered maps of ‘‘ Bode’s Constellations.” 
* Our readers will remember the announcement at Bombay, in October last, of 
the discovery of Biela’s Comet, which from its being so stationary was supposed 
to be coming direct towards the earth: the situation of the object proved it to be 
the nebula in Andromeda, No. 3. When really seen by Sir John HerscueExt on the 
23rd September and again in November, the comet did however really appear ex- 
act.y similar to a faint circular nebula.
