COMPARATIVE BRIGHTNESS OF THE STARS. 445 



Note to Piscis austrinus. 



September 22, 1795. This constellation, on account of its low situation, can be of 

 no use for comparative magnitudes. The opportunities of observing it must be so 

 scarce that no discoveries of changes can be made in it. I can see no other star with 

 the naked eye but those I have equated [viz., 24 and 18. The observations of other 

 stars of this constellation were made two years later. J. H.]. 



Notes to Scorpius. 



16 Should be about 3 or 4 minutes nearer to 15. FLAMSTEED'S observation, p. 197, 

 leaves the ZD doubtful. 



21 Is of a very brilliant ruddy light. Is of a pale garnet colour : it seems to be 



the most coloured of all the large stars. Its low situation probably contributes to it. 



25 Either does not exist or is misplaced. There is a star about 4 from 23 and 

 2f from 22, which may be the star if misplaced. In that case the RA of 25 should 

 be 1 and it will be 22 7" 25. Several stars of Serpentarius are so small that 25 

 may exist. 



26 Being low it may be larger than 14, for I make no allowance in my 

 observations. 



Notes to Serpens. 



17 There are two of 17 but little different in brightness. I have taken the 

 brightest of them. 



33 Does not exist. FLAMSTEED never observed it. 



42 Does not exist. The place where it should be, according to the catalogue, 

 cannot be mistaken. FLAMSTEED never observed it. 50 Libra? not far from it is in 

 its place. 



(63) = I Aquila3 and less than X Aquilae. 



64 Is the largest of two. 



Notes to Serpentarius (Ophiuchus). 



3 (u) is misplaced in Atlas 1. It should be about +1 in RA. A star f north of 

 it, observed by FLAMSTEED, pp. 442, 443, is in its place. 



6 Does not exist. FLAMSTEED never observed it. 



13 3 np 13 is a star not marked in FLAMSTEED = 20. 



26 28 26 has another near it larger than 28. 



30 Seems not to be rightly placed. 



38 31 Scorpii is 38. 



46 A larger star than 46 is just by, but not marked in Atlas. 46 does not 



exist.
