218 Dr. Herschel's Method of observing the 
Page 67 a star was observed without time, but by page 71 and 
122 it appears that the defective observation belongs to 2. 
There is a star 8 or 9m, about 50' from 2, T 20' from 9, and 
and i° 30' from 6 ; and calling that star 5, its brightness may 
be expressed by 9 — 5. 
10. “ Sept. 15, 1783. 10 is at least 4m. It is larger than 
13.” If the authority of the catalogue be good, there can be 
no doubt of a change since Flamsteed's time ; but in his ob- 
servations there is no magnitude to this star. 
12 Is less than 8, contrary to the catalogue. “ Sept. 7, 1784, 
12 ( (p ) 6m." In Flamsteed's observations there is no mag- 
nitude to either of the stars. 
13 Is less than 32, contrary to the catalogue. But in the 
observations 13 has no magnitude, 
17 Is less than 21, contrary to the catalogue. But in the 
observations neither of the stars have any magnitude. 
18 Is larger than 64, contrary to the catalogue. But in 
Flamsteed’s observations neither of the stars have any mag- 
nitude. 
21 Is larger than 41, contrary to the catalogue. But 21 is 
without magnitude in the observations. 
23. The expression 13 , 23 does not agree with the cata- 
logue. But 13 has no magnitude in the observations. 
27 Is less than 36, contrary to the catalogue ; but in F lam- 
steed's observations are no magnitudes of these stars. 
30 Is less than 32, contrary to the catalogue ; it is also 
contrary to the observations, which give 30 3m and 32 
6.5m. 
31 Is larger than 30, contrary to the catalogue. It is also 
contrary to the -magnitudes given in the observations 44 Sept.
