 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 32° 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° 27' sf; the only 

 mode to reconcile the differences is, to suppose that in one 

 instance the micrometer has been erroneously read lo de- 

 grees."
