30 Is 58 Camelopardali. 
35. Flamsteed has no observation of this star; but, as it is 
marked 7m in the British catalogue, and has a line allotted to it, 
my Atlas and stars have been numbered so as to take it in ; and 
the numbers I have used with double stars and other objects 
where the stars in Lynx after the 35th 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 i°. 
Notes to Lyra. 
10 This is one of our periodical stars discovered by Mr. 
Goodricke ; its period is about 6 days 9 hours. See Phil. 
Trans. Vol. LXXVI. page 197. The greatest variation of 
its light, as far as I have observed, is from “ 10 . 14 to 
“ 6 -{- 7i 10.” The expression 6 -f- 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 0 in 
PD ; and this star will then agree with 12 Lyrae Hevelii. 
19 The British catalogue requires a correction of + 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. 
12 “ Sept. 5, 1798, This star, which has no time in Flam- 
“ steed’s observations, is placed a little too forward ; or requires 
“ about 10' in RA.”
