No. CCCLXXXVII. R. A. o^ 26™ ; Decl. 17° 6^ N. 



Struve, 8 ; Hist. Csel. 478.

The measures are so excessively difficult, that I have but little confidence in the 

 results. 



North preceding, in the field with this, is a faint double star of the 4th or 5 th 

 class ; but it is not measurable with this instrument.

Measures of such difficulty, that I consider them little else than approximations ; 

 the small star will not bear the slightest illumination j would be a proper object 

 for Mr. Herschel's 20-feet Reflector.
