objects where the stars in Lynx after the 35 th are concerned, must be reckoned 

 accordingly. 



37 " Dec. 4, 1796, This star is nearer to 25 than it is marked in the Atlas." 

 The ra should be corrected + l °- 



Notes to Lyra. — (3 (10) This is one of our periodical stars discovered by Mr. 

 Goodricke ; its period is about 6 days 9 hours. The greatest variation of its light, 

 as far as I have observed, is from " 10 . 14 to 6 + 7 i 10." The expression 6 + 7 

 is borrowed from algebra, and is always to be understood as has been explained in 

 the note to 35 Draconis. 



^ (16) The British catalogue requires a correction of — 9 in pd ; and this star 

 will then agree with 1 2 Lyrae Hevelii. 



» (19) The British catalogue requires a correction of -J- 8° in pd. 



Notes to Perseus. — 5 Flamsteed has no observation of this star ; but there is a 

 star exactly in the place pointed out by the British catalogue. 



10 Does not exist. Flamsteed never observed it. 



q (12) " Sept. 5, 1798. This star, which has no time in Flamsteed's observa- 

 tions, is placed a little too forward ; or requires about -f 10' in ra." 



14. " Sept. 4, 1798- The time of this star is marked doubtful by Flamsteed, 

 p. 2 1 4 ; but it seems to be in the situation where the British catalogue places it.' 



15 Is lost. Flamsteed observed it Jan. 17, 1693, p. 186; but it is not to be 

 seen in the place pointed out by that observation. See Bode's Ast. Jahr-Buch for 

 1794, p. 97. 



19 Does not exist. There is an observation in p. 185, which has produced this 

 star, but it belongs to 18 ; for the star is lettered t, and a memorandum says, " Post 

 transitum." See also Bode's Ast. Jahr-Buch for 1788, p. 172. 



s (24) " Sept. 4, 1798. The place of this star in the British catalogue wants a 

 correction of + 56' in pd, and — 45" in ra." 



|3 (26) Is a periodical star. It has been noticed in the last century as subject to 

 change, by Montanari and Maraldi ; but its being periodical was discovered by 

 Mr. Goodricke, in 1783, who fixed the time of its change at 2 d 20 h 48 m 56 s . 

 I have seen it when brightest, " 6 Arietis , 26 -— 23", and when most diminished, 

 " 26 , 25". 



0' (38) Sept. 5, 1798. The British catalogue requires nearly + 2° in ra, and 

 — 13' in pd ; at least there is no other star that can be taken for it." 



n (42) " Sept. 4, 1798. The British catalogue requires a correction of + 13 

 in pd." 



Notes to Sextans. — 1 Is 10 Leonis. 10 Is 25 Leonis. 11 Is 28 Leonis. 



12 " March 17, 1797- This star is misplaced in the British catalogue; the pd 

 should be corrected + 1°." 



28 " March 21, 1797- This star is misplaced in the British catalogue, and re- 

 quires a correction of + 20' in ra, and + 1° in pd."
