 The star C will not bear even the least illumination. No observations of 

 distance can be gotten ; but by estimation, it is about two-thirds of the distance 

 from A, that B is. The night is remarkably fine ; indeed on no other can either 

 of the stars B or C be seen with this instrument.

Of C no distances can be procured. The night is unusually fine, but the star will 

 not bear the slightest illumination.
