There is some reason to suppose that Sir W. Herschel 
has erroneously called this star ur Cygni, which it certainly 
is not ; u as far as my instruments can inform me is single.

Double; 6th and 12th, or 15th magnitudes; the small 
star bears no illumination ; it is the double star alluded to in 
the observations of 210 (Bode) Cygni, which star it follows a 
few seconds of time.

The measures are so extremely difficult, that the results are I fear little better 
than guesses. 210 (Bode) Cygni is in the field; is more easily measured than this 
star ; and, by very cautious estimation, the distance between the two stars of u 3 
Cygni is less than that of the two stars of 210 (Bode) Cygni, by six or seven seconds.

210 (Bode) Cygni which I have just measured is difficult enough ; it is however 
easy when compared with this. My confidence in the accuracy of these results is 
but little. Night at present tolerably favourable. 
* The star here measured is not IV. 24, in spite of the general agreement of their 
angles. The descriptions are totally at variance ; and in the MS. there is a remark, 
" My 24th star in class IV. is miscalled ; it should be Fl. 46* Cygni (a 3 ) adjacens, 
or ad 46 am Cygni a 3 Cygni is in fact IV. 23. (H),
