pole, in all 7730 in number. e stars bear current numbers, 
in order of R. A., and the synonym in other catalogues, and 
the magnitude, together with the R. A. and declination are 
given for each star. f the number mentioned, 6733 belong 
to the southern heavens, and 997 to the belt of 10° in width, 
north of the equator. They belong to 66 different constellations.

of them exaggerating in general its brightness as seen at Cor-
