/. The Discovery of a Comet. By Miss Caroline Herschel. Vol. LXXXIV. 



Anno 1794. p. 1. 

 Last night I discovered a comet near 1st (<?) Ophiuchi, but clouds covering 

 the part of the heavens where it was, its place could not be obtained. My 

 brother has just now (7 o'clock) determined its situation, as follows : The 

 comet precedes the 1st {S) Ophiuchi 6[" 34' in time, and is 1° 25' more north 

 than that star. — Slough, Oct. 8, 1793.
