11G ASTRONOMICAL OBSERVATIONS 



11th. Saturn's ring well defined; the ansae are evidently di- 

 minishing : — two satellites visible. 



14th. Emersion of the 2d satellite of Jupiter, observed at 

 12 h 41' 54" mean time, or 12^ 45' 52" apparent time : — night 

 clear: — magnifying power 100. 



16th. Saturn's ring well defined: — the ansae not perceptibly 

 diminished since the 11th. 



27th. Occultation of a star, supposed to be ? Leonis (SI) 

 observed at 8 h 17' 53" mean time, or S h 21' 10" apparent 

 time. 



Saturn's ring well defined : — the ansae decreasing, and appear 

 more luminous towards their extremities than near the body 

 of Jupiter: two satellites very distinct. 



June 6th. The night very clear and fine; Saturn's ring was 

 particularly attended to : the ansa? appeared more luminous 

 and sparkling toward their extremities, than near the body of 

 the planet: — three satellites were visible. 



9th. Saturn's ring yet visible: — the ansae were distinct during 

 the twilight, but faint afterwards. 



13th. Immersion of the 3d satellite of Jupiter, observed at 

 9 h 7' 56" mean time, or 9 h 8' 25" apparent time: — the planet 

 and satellites tolerably distinct: — magnifying power 100. 



15th. Saturn's ring decreasing: the ansae were scarcely de- 

 scernable after the end of twilight. 



17th. Emersion of the 1st satellite of Jupiter, observed at 

 9 h 45' 43" mean time, or 9 h 45' 21" apparent time. — The 

 night clear, and the planet and satellites well defined: — mag- 

 nifying power 100. 



Saturn's ring very faint: — the ansae were invisible after the 

 end of twilight. 



18th. Saturn's ring more faint than last evening: the ansae 

 disappeared before the end of twilight. 



21st. Saturn's ring almost invisible: — the ansae would fre- 

 quently disappear for whole minutes, and then become visible 

 for a few minutes more. 



22d. The ring of Saturn has almost disappeared : the western 

 ansa only visible, and that for but a few seconds at a time.
