Dr. Herschel’s Obfervations on the 
23 59. The ad, about i| or 1*. dia. of ^ p. the 
Obfervations on the firjt fatellite of Saturn. 
July 18. 19 50. The following part of the ring of Saturn, 
which is a very thin lucid line, ends in a bright point like a 
very faint fatellite (A). 
I fuppofe the bright point on the f. part of the ring to be a 
very lmall fixed ftar (B). 
20 14. The bright point on the following part of R. feems 
to have its whole dia. towards the north ; and in all appearance 
adheres to the line. 
o 48. Poffibly the bright point on the nf. part of the ring 
may be one of the fatellites, and one of the before fuppofed fa- 
tellites may be a fmall fixed ftar (C). 
(Y)6h. 7' 58". 3 ° 7 °> 8 - . . 
(A) 11 h 52' 21". 146,7. This lliews, that the bright point was the lit 
fatellite. , . . 
(B) Being the firlt night of my viewing the fatellites this year, their place. 
were unknown. The 6th, which was in view, I took for the ill fatellite but, 
the 2d, 3d, and 4th being alfo before me, there remained only the fuppofition ot 
fome fmall fixed liar to account for the bright point. _ 
(C) The motion of the bright point on the ring led me to the fuppofition 0 
its being a fatellite ; and, to make room for one, it occurred, that one of the 
others might be a liar : for ftill the thought of an unknown fatellite did not 
happen to ilrike me. I Ihould have made an attempt to calculate the places of 
the fatellites by the manufcript tables of M. oe u Lande, which are now 
printed in the Connofance des Temps for 1791 ; but as there chanced to be 
an erratum of one day’s motion in the epoch* of all the fatellites for 1788, 0 
which I was not aware, I had fo little fatisfaflion from them the year before, t at 
1 laid them by as ufelefs, and refolved to inveftigate the epoch* and revolutions 
:0f the fatellites from my own obfervations.
