The qu eft ion then prefented itfelf very naturally, what to 
make of thefe protuberant points? To admit two or three 
more fatellites by way of folving fuch phaenomena appeared to 
me too hazardous an hypothefis ; etpecially as thefe lucid 
points, though fome of them had a motion, did not leem 
willing to conform to the criterion I had before ufed of coming 
off the ring, and {hewing themfelves as la..ellites. Ann yet a 
fufpicion of at leaft one more fateilite would often return ; it 
was even confiderably ftrengthened when I dilcovered, by 
means of re-calculating with great precifion the whole leries of 
obfervations, that in the beginning of the featon there had 
been fome few miftakes in the names of the fatellites, when 
the obfervations of them were entered in the journal. In 
fetting them right, which threw a great light upon the revolu- 
tion of the 6th, and more efpecially upon that of the 7th, I 
found alfo, that fome of the obfervations which were entered 
by the name of the 7th fateilite could not belong to that, nor 
to any other known one. It remained therefore to be examined 
whether there might not be fufficient ground to fufpedt the 
exiftence of an eighth fateilite. 
In this fituation of things, I thought it moft advifable to 
draw out the whole feries of obfervations in a paper, beginning 
at the 5th fateilite, and thus gradually through the 4th, 3d, 
2d, 1 ft, 6th, and 7th, to approach towards the center of Sa- 
turn ; that it might appear at laft what obfervations were left 
■unaccounted for. By this means alfo it will be feen clearly 
with how fcrupulous an attention the identity of every fateilite 
has been afcertained; and with a view to give the ftrongeft 
fatisfa&ion in this refpedt, at leaf!; one obfervation of each has 
been calculated for each night ; and the place thus computed is
