The evening of Oct hpi “4th, — being beautifully clear, 
I ‘htained six observations of the comet with the ri Th 
my journal as A and B. A was of the 7th magnitude and Bb of 
the 63°; the former preceded the comet in right ascension’ me 
the latter followed it. The fourth comparison was made 
another star C of the 8th magnitude preceding the comet ee 
B following it. The fifth comparison was made with # and the 
sixth with C. A reduction of the transits in which A and 
were both observed gave the following results for diffconces of 
right ascension of the two stars, B being east of A :—

Tt was grees to determine with accuracy the difference of 
north p stance as B passed very near the centre of the

of the comet, the star . another star D of the 6% ye which

ollowing results for difference of right ascension and north
