8h. 12m. to 10h. 30m. muft have moved towards the 
eaft about ,",th of its orbit, which correfponds with the 
arc kV. 
It is alfo worthy of remark, that we diftinguithed this fa- 
tellite with a thirteen feet reflector during ferene weather, 
by moonlight, and only at the diftance of 1; degree from 
the moon; and the circumftance that, in the courfe of fe- 
venteen days, we found it eight times exaély in thofe pofi- 
tions where, according to Herfchel’s period, it ought to 
ftand, confirms in the completeft manner the accuracy of 
that period. 
Obfervations which confirm what others have difcovered 
with large telefcopes contain indeed nothing new; but 
they are, however, ftill valuable not only to the obferver, but 
to many amateurs, who often wifh to try whether they 
have inftruments that poffeis a fufficiently ftrong power ; 
and under that view I have confidered it as my duty to give 
the above at full length, felected from a great many which I 
made in regard to the fatellites of Saturn. 
I fhall pafs over feveral made on the fixth fatellite of Sa- 
turn, which feem to betray irregularities in it; and only re- 
mark that, according to our obfervations, this fixth fatellite, 
like the whole of Jupiter’s four, and the five outermoft of 
Saturn, are, inall probability, fubjeét to a variation of their 
light.
