observers agree that it is as round and as sharply defined as 
possible ; neither of us can entertain the slightest suspicion of 
seeing it elongated in any direction ; with 787 it has the 
appearance of a planetary disc, and is a most beautiful object: 
it is so extremely steady, that with this high power there is 
not any difficulty in keeping it bisected by the wire of the 
micrometer, when placed perpendicular to the diurnal motion.

“ If the position 3 2° 58' sf be exact, there must be some 
monstrous error in that given to the Royal Society in the 
first memoir, where the position stands 45 0 27' sf; the only 
mode to reconcile the differences is, to suppose that in one 
instance the micrometer has been erroneously read 10 de- 
grees.”
