There is some reason to suppose that Sir W. Herschel 

 has erroneously called this star «^ Cygni, which it certainly 

 is not ; w* 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 «' 

 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 («^) adjacens, 

 or ad 46 am Cygni ;" u^ Cygni is in fact IV. 23. (H).
