By directing the eye to another part of the field, I can suspect the star C to be 

 double ; if so, its small star is more minute than the small one of a Lyrae ; is south 

 preceding, and is rather nearer to C, than is B to A. Night remarkably fine; stars 

 very steady.

The small star is light blue, and bears only a very feeble illumination. Night 

 clear, but the stars of low altitude are very unsteady.

The night is very favourable for difficult observations ; but although the stars 

 are very steady, yet the measures are so extremely difficult, that I fear they merit 

 but little confidence. Sir W. Herschel having described it as a triple star, I 

 applied a power of 413, but no third star could be even suspected.
