The night having become hazy, the stars are now remarkably steady. During 
the observations of position, the haze took off the flare of the large star, and left 
the small one sufficiently distinct under a good illumination ; after however the 
position series was procured, a dense fog supervened, the small star became very 
indistinct, and shortly was invisible ; on this account, no more measures of distance 
could be obtained, and those gotten are deserving of little confidence.
