Obfervations on the feventh fatellite of Saturn . 
Sept. 8. 22 51. The firjl fatellite f the dia. or a little lefs of 
the projection ff. R. (A). 
Sept. 14. 1 29. A fuppofed 7th fat. exceffively faint, § pro- 
jection p. R. exactly in the line of the R. fainter than the laft 
new one. 
1 46. The fuppofed 7th half a projection p. the R. (B). 
Sept. 17. 21 o. A fecond new fatellite exceffively faint, f 
projection p. the edge of the R. (C). 
22 55. The new, or 7th fat. J projection p. R. fo exceffively 
fmall that, if I had not feen it before, it would have been 
irnpoffible to perceive it now. 
(A) Not being acquainted with more than fix fatellites, and having the 2d, 3d, 
4th, 5th, and 6th in view, it was natural enough to call the remaining one, on 
which this obfervation is made, the ill; but from the note M of the ill fat. it 
appears, that it could not be in the place where this was feen ; and by calculating 
from the tables of the 7th fat. we have its place for nh. 28' 45". io6°,o, 
which agrees exa< 5 Hy with the fituation pointed out. From a figure, it appears, 
that the fat. was extremely fmall, and lefs than half its diameter fouth of the 
dine of the R. 
(B) I was now on the look-out for very fmall flars that were in any fituation 
likely to be fatellites of T? , and always noticed them : for inftance, <s Sept. 11. 
li 20 h. 42'. A fuppofed 7th fat, exactly in the line of the R. or a very little 
4 1 fouth, exceffively faint, only to be feen when I hide b by the field bar. Sept. 
“ H- 20 h. 40'. The 7th of Sept. 11. is left in its place.” So here this fup- 
pofed 7th is marked down, and Sept. 16. 20 h. 13' I find it is laid, that “ the 
44 fuppofed 7th of the 14th is a fmall fixed liar, left in the place where it was that 
46 evening; but as the configuration of liars which pointed out this fuppofed 7th 
was very eoarfe, and hardly fufficient to determine the place, and as by calculation 
it appears, that the 7th fatellite was in thd fituation where this obfervation places 
it, at 13 h. 59' 43", viz. 278^2, it is probable enough, that I favv thereat 
Satellite this evening. (C) 9 b. 2' 43". 265°,6,
