Orionis ; but the light of Rigel being more brilliant than that 
of Procyon, a continuance of its impression, when we look a 
good while, occasions an increase ; and it becomes 19 Orio-

29 There is no observation of Flamsteed of this star. 
41 There is no observation of this star by Flamsteed. 
51 Flamsteed observed this star Dec. 16, 1691. The ob- 
servation, however, is marked defective in zenith-distance. 
There is a star, about 9 or 10 m, near the place where 51

small stars about the place of 55.

52 and 53 are not laid down in Atlas as they are in the 
heavens ; and on examining Flamsteed’s observation on page 
208, it appears that the catalogue is erroneous ; for by that 
observation 52 is the most north, and 53 the most south, con- 
trary to the catalogue.
