the changeable Stars . ^09 
Come fmall ftars of about the 8th magnitude, none of which 
are near as bright as the 2d v Libras, 
Ptol. and Ul. Beigh’s N° 6 of the unformed in Libra, 
In examining different Catalogues I do not find this ftar in 
any other than the above, though it is marked of the 4th 
magnitude. If Ptolemy had not the a it might be thought to 
be that. In 1785 I frequently obferved a ftar of the 7th mag- 
nitude very near its place, which appeared rather lefs than 
Flamsteed’s 41. Flamsteed has not this little ftar in his 
Catalogue ; but he obferved it May 9, 1 681 , 
n Librae. 
This ftar is thought to be variable. I am not of that opi- 
nion ; though certainly it is rather lingular that Hevelius, 
whofe attention was directed to this part of the heavens, to 
find Tycho’s i ith, did not obferve the x ; and the more fo, as 
he has noticed two much lefler ftars not far from it. During 
thefe three years I have found the x conftantly of the 5th mag- 
nitude, being lefs than ip or 0, equal to X 9 and brighter Lhan ^. 
Tycho’s n th Librae. 
Hevelxus fays he could not find a ftar of the 4th magni- 
tude in Libra noticed by Tycho. This muft be Tycho’s 
1 ith, fince he has all the others. It was not vifible in 1783, 
1784, and 1785, nor probably ever exifted ; for it is, I think, 
evident, that this nth is no other than the k 9 with an error of 
two degrees in longitude.
