the series of observations. It then exhibited an elongated 
orm, somewhat rounded at its anterior margin, and shading 
away to form the tail, which was but little inferior in bright- 
the telescope, although my ephemeris was so accurate as to 
leave no doubt concerning its position in the field. 
The positions of the comparison-stars employed on the 7th, 
8th and 11th cannot be sharply determined for several months. 
The observations on other days give the following results 
which are uncorrected for parallax, or aberration.
