afcribed to their fmallnefs, and partly to being fo near the 
light of the ring and diik of Saturn. Strong fufpicions ot 
the esiftcnce of a fixth fatellite I have long entertained ; and, 
if I had been more at leifure two years ago, when the d.ico- 
very of the two Georgian fatellites took me as it were off the 
fcent, I fhould certainly have been able to announce its exift- 
ence as early as the 19th of Auguft, >787,' when, at tib> 
I*/ S 6 ", I faw, and marked it down as being probably, a 
fixth fatellite, which was then about 12 degrees paft its greateft 
preceding elongation. But, as 1 obferved before, not having 
time to give my thoughts to the fubject, 1 relerved a full m- 
veftigation of the number of fatellites, and the nature or the 
rino- of Saturn for a future opportunity. B Ji ks, not having 
tmy tables of the fatellites, 1 could not confidently lay, whether 
the fifth fatellite was not one of the live which 1 perceived m 
motion that night, though afterwards I found, that the nal 
fifth had alio been in view, and was marked down as a U .r, 
by the letter b, in a figure 1 delineated of datum and *» Utel- 
lites that evening. 
In the year 1788 very little could be done towards a diico- 
very, as my twenty-feet fpeculum was lo much tarmlhed by 
% enith [weeps, in which it had been more than utually expoted 
to falling dews, that I could hardly fee the Georgian l.udhus. 
In hopes of great fuccefs with my forty-feet ipeculum, I de- 
ferred the attack upon Saturn till that fhould be timlhed ; and 
having taken an early opportunity of direaing it to Saturn, 
the very firft moment I faw the planet, which was the 28th 
of laft Auguft, I was prefented with a view of fix of its iatel- 
lites, in fuch a fituation, and fo bright, as rendered it impol- 
fi'ble to miftake them, or not to fee them. Trie retrogra e 
motion of Saturn amounted to nearly 4i minutes per ay,
