Stars that have changed their magnitude mice plamstead’s 
time. 
Draconis is fo much lefs than / 3 , which is fet down as a 
fmaller ftar in flamstead’s catalogue, that the change of 
magnitude cannot be doubted. 
/3 Ceti marked of the 3d, and a Ceti of the 2d, are evidently 
the reverfe, (3 being by much the larger ftar. I have men- 
tioned this circumftance in my obfervations on the periodical 
ftar in Collo Ceti *, and it feems now as if the difference be- 
tween the magnitudes of thefe two ftars was ftill increafing. 
£Serpentis is not near fo large as r n and yet we find flam- 
stead has placed them in the fame clafs : however, we cannot 
intirely confide in the marks of the magnitudes when two ftars 
are placed in the fame clafs, fnce every order admits of a 
conliderable variety ; but when the marks contradict experience 
fo far as to defcribe one ftar, forinftance, of the third, and ano- 
ther of the 4th magnitude, when obfervation fhews the latter 
to be of the 3d and the former of the 4th, I think we can 
hardly doubt but that there muft have been a change. 
7] Cygni is a brighter ftar than though marked by flam- 
stead of a lei's magnitude. 
The 2d Urfe minoris is marked of the 6th magnitude, but 
is certainly intitled to the 5th.

(3 Trianguli is much larger than a. 
y Aquike is much larger than jG.
