Dr. Herschel's First Catalogue of the 
Notes to Aquarius. 
2 “ August 2, 1788. 2c-feet reflector 2 (e) 4.3m FL.5.4H1/' 
The difference amounts to one whole magnitude. In Flam- 
steed's observations no magnitude is mentioned. 
6 Is less than 13, and very little brighter than 18. The 
former is contrary to the catalogue, and the latter inconsistent 
with the magnitude assigned to 18. None of these stars ha\e 
any magnitude in Flamsteed's observations. 
8 Is larger than 9, contrary to the catalogue. In the ob- 
servations 8 is 6m, but 9 has no magnitude. 
13 Is less than 23, and is larger than 6 ; both are contrary 
to the catalogue. There are no magnitudes of either of these 
stars in Flamsteed's observations. 
23 Is larger than 13, contrary to the catalogue, and from 
the expression 2-23 (see 2) it appears that 23 is underva- 
lued by Flamsteed, or has changed its lustre. Flamsteed's 
observations give no magnitude of 23.
