n Cygni is a brighter star than y^ though marked by Flamsteed of a less 

 magnitude. 



Tbe 2d Ursae minoris is marked of the 6th magnitude, but is certainly inti- 

 tled to the 5th. 



n Bootis is much larger than £. — i Delphini is much larger than x. — 13 Trian- 

 gnli is much larger than «. — y Aquilae is much larger than |3. — <r Sagittarii is 

 larger than S, y, and e, though marked of an inferior magnitude. — $ Canis ma- 

 ]oris is larger than (3, and yet is marked to be less. — n Serpentis is so much larger 

 than £, that they certainly should not have been put in the same order of mag- 

 nitude. 



x Serpen tarii is larger than y and i, though marked to be of a less magnitude 

 than either. 



(3 Equulei is so much less than a that it could hardly deserve to be put in the 

 same class. 



2 Delphini is larger than s, though placed in an inferior order. 



e Bootis is so much larger than £ that it should not be put into the same order. 



S Sagittae is larger than a and p, though placed in a lower order of magnitude. 



S Ursse majoris is less than either e, £, or n, though it is marked of a superior 

 order of magnitude. Besides, it is evidently visible, that J cannot be intitled to 

 more than the 4th magnitude, or at most to between the 4th and 3d; on the 

 contrary, e, £, and n, should be of the 2d, or at least between the 2d and 3d; 

 all which is very different from Flamsteed's account of those remarkable stars. 



a, Ursae majoris is less than any star marked of the same magnitude, and can- 

 not have the least pretension to be called a star of between the 1st and 2d, as 

 Flamsteed has marked it. 



The 1st and 2d Hydras are noted by Flamsteed as being of the 4th magnitude, 

 whereas they now are only of the 8th or 9th. It is remarkable, that the 30th 

 Monocerotis, which is situated between them, has retained the order assigned to 

 it by Flamsteed, and being of the 6th serves to point out the change of the other 

 two in a very evident manner. 



y Lyra? is much larger than (3. — The change in the magnitudes of the 31st 

 and 34th Draconis is very striking, these two stars being just the contrary of 

 what they are marked in Flamsteed's catalogue. The 31st, from the 7th is in- 

 creased to the 4th: and the 34th, from being a star between the 4th and 5th, is 

 reduced to one of the 6th, if not 7th magnitude. 



The 44th Cancri is much too small for the 6th magnitude. As s and others 

 arc marked of the 6th, this, on being compared to them, can be intitled to no 

 more than the &th or 9th order. 



The 96th Tauri is small enough to be of the 8th magnitude, though marked 

 as one of the 6th.
