80th and 81ft. They are no more to be fecn. I locked for 
l hem, in October, 1781, but could not find them ; and have 
fince frequently examined that part of the heavens with no 
better fuccefs, though the fmall liars x, z, y, of the fixth 
magnitude, not tar from the place where the former thou Id be, 
appear very plainly in a fine evening.. On referring to my pre- 
ceding review in Augufl, 1780, I find, that I then alfo examined 
the left toot of Hercules, and had thefe liars been there at that 
time I mu ft have teen them ; for not only t of the fourth mag- 
nitude, but y of the fixth, is in the hid of ftars examined ; 
and the place of the Both and 81ft is very near directly be- 
tween them. 
In the northern claw of Cancer flamstead has placed three 
ftars of the fixth magnitude; they are the 53d, 55th, and ^6th 
of his catalogue. The latter of them is vanifhed. Its place 
and magnitude are fo well pointed out by the other two ftars, 
that there can remain no doubt of this remarkable change. We 
find a very fmall tclelcopic ftar near the place where the 56th 
fhould be : this may pofiibiy be the remains of that v an i firing 
flat ; but that mav be afcertained bv thole agronomical gentle- 
men, who, having fixed inflruments, can determine the place of 
this fmall ftar, and compare it with the 56th of Cancer, when 
it will appear how far their places agree. I milled it firfl in 
February, 1782, and have fince looked often for it in vain. 
The 19th Perfei, a ftar of the 6th magnitude, is either loft, 
or fo confiderablv removed from its place in flamstead’s 
time, that it is no longer to be known. What gives occafion 
for a fulpicion of its having been removed is, that we find no 
ftar of the fixth magnitude in the place where this fhould be ; 
whereas, about a degree following that iituation, there is one 
of that, or the fifth magnitude, not taken notice of by flam- 
stead*
