The 6'2d Arietis is of the 5th magnitude, though only marked of the 6th. 

 The magnitudes of the 12th and 14th Lyncis are just the reverse in the hea- 

 vens to what Flamsteed has marked them. This denotes a double change of a 

 star from the 5th to the 7th, and from the 7th to the 5th magnitude. — The 38th 

 Persei, marked of the 6th magnitude, is increased so as to be equal to 8 and x 

 of the 4th. Also, is less than t contrary to Flamsteed. — The 8th Monocerotis 

 is less than the 76th Orion is, though the former should be of the 4 th, and the 

 latter only of the 6th magnitude. — The 23d Geminorum, though marked of the 

 5th, is less than the 21st of between the 6th and 7 th magnitude. 



The 26th Orionis is much too small for the magnitude of which it is marked to 

 be, or rather is lost ; for we can hardly take any one of the remaining telescopic 

 stars for it. 



£ Leonis in Flamsteed's time was of the 4th ; but is now less than a star of the 

 5 th magnitude. 



3. Stars newly come to be visible. — Near Lacerta's tail-end is a star of between 

 the 4th and 5th magnitude, not mentioned in Flamsteed's catalogue, though the 

 1st Lacertae, not far from that place, is recorded. 



The star of the 5th magnitude following t Persei, supposed to be u removed, is 

 most likely new, unless future observations we're to favour the supposed motion 

 of this star. It is among the double stars of my 4th class, so that it will be easy 

 to detect its proper motion. 



A very considerable star, not marked by Flamsteed, will be found near the 

 head of Cepheus. Its right ascension in time, is about 2 m 19 s preceding Flam- 

 steed's 10th Cephei, and it is about 2° 20' 3" more south than the same star. A 

 considerable star in a direction from the 68th Geminorum towards the 6lst is not 

 to be found in Fiamsteed. A star of a considerable magnitude preceding the 1st 

 Equulei is not contained in Flamsteed's catalogue. It is a double star of the first 

 class, the 6lst of Mr. H.'s 2d collection, where measures of it will be found. 



A considerable star following the 1st Sextantis, and another following the 7th, 

 are not inserted. 



Between (3 Cancri and S Hydrae is a very considerable star not marked by 

 Flamsteed, though its situation is very remarkable. As the constellation of Can- 

 cer contains so rich a collection of very small stars, it is to be wondered how a 

 star of such consequence could be omitted, if it had been visible in Flamsteed's 

 time. — Nearly 1^- degree north following $ Herculis, almost in the direction of S 

 and v, is a star of the 5th, or between the 4th and 5th magnitude, very visible 

 to the naked eye. We can hardly think Flamsteed could have overlooked it, had 

 it been there in his time. — About 3° south preceding y Bootis, a considerable star 

 not in Flamsteed's catalogue of the 6th magnitude ; and south preceding A, an- 

 other, almost as large.
