by those astronomical gentlemen, who, having fixed instruments, can determine 

 the place of this small star, and compare it with the 56th of Cancer, when it 

 will appear how far their places agree. 



The 19th Persei, a star of the 6th magnitude, is either lost, or so consider- 

 ably removed from its place in Flamsteed's time, that it is no longer to be known. 

 — The 108th Piscium, a star of the 6th magnitude, near the head of Aries is 

 lost. — Two stars of the 6th magnitude, the 73d and 74th Cancri, in the southern 

 claw, are either both lost, or at least have undergone such a remarkable change 

 of magnitude, and one of them of place, that it is hardly possible to know them 

 any longer. — The 8th Hydrae is lost. There is a star just by, which may be the 

 31st Monocerotis. If this should be the 8th Hydras, and a small star near the 

 latter should agree with the place of the 31st Monocerotis, then the magnitudes 

 will be quite contrary to what Flamsteed makes them. There must, at all events, 

 have been a very remarkable change. — The 26th Cancri is lost. — The 62d Orionis 

 is lost; and a star near the 54th and 51st is not taken notice of by Flamsteed. 

 Perhaps the 62d has changed place; if this should be the case, it must have a 

 very considerable motion. — The 71st Herculis, a star of the 5th magnitude, is 

 lost. The 70th and 71st are so near each other by Flamsteed's catalogue, that 

 it cannot be determined without fixed instruments, which is the star wanting. 

 There is a small telescopic star, within about 30 minutes north following, in a 

 direction towards ju. Lyrae; if that should be the 71st, it is wonderfully changed 

 both in place and size. 



The 34th Comas Berenices is lost: Flamsteed has marked it as a star of the 

 5th magnitude. 



The 19th of the same constellation is also lost, or moved and changed in 

 magnitude. 



The 40th and 41st Draconis have undergone so great an alteration of place 

 that we cannot possibly mistake it; for in Flamsteed's time they were above 3 

 minutes asunder, whereas now their distance is much less than half a minute. — 

 There seems to be an alteration in the place of the 65th, 64th, 54th, and 57th 

 Orionis; but without fixed instruments it cannot be ascertained in which of the 

 stars it is. 



2. Hears that have changed their magnitude since Flamsteed's time. — a Draconis 

 is so much less than (3, which is set down as a smaller star in Flamsteed's cata- 

 logue, that the change of magnitude cannot be doubted. — (3 Ceti, marked of 

 the 3d, and a Ceti of the 2d, are evidently the reverse, (3 being by much the 

 larger star. 



C, Serpentis is not near so large as n, and yet we find Flamsteed has placed them 

 irTthe same class.
