The number of stars between the north pole and the circle thirty-five degrees south of the equator is about as follows:—
Of the 1st magnitude about 14 stars.
Of the 2d magnitude about 48 stars.
Of the 3d magnitude about 152 stars.
Of the 4th magnitude about 313 stars.
Of the 5th magnitude about 854 stars.
Of the 6th magnitude about 2010 stars.
——
Total visible to naked eye 3391 stars.
The number of stars of the several magnitudes is approximately in inverse proportion to that of their brightness, the ratio being a little greater in the higher magnitudes, and probably a little less in the lower ones.
