72 Dr. Herschel’s Discovery of four additional 
“ have however had several perfect glimpses of it. It seems to 
“ be about the most contracted part of its orbit.” 
March 6. The supposed 3d and 4th satellites of March 3th 
were imagined to have been gone from their former places; 
but were seen the 7th, with this memorandum. “ I mistook 
them last night for other stars, they being so large that I did 
not know them again.” 
“ March 9. The 2d satellite is nearer the planet than the 
“ first, and on that account appears smaller.” 
“ Dec. 9, 1791. I do not perceive the 1st satellite.” 
“ Feb. 13, 1792. 6 h 16'. The 3d supposed satellite of last 
“ night is a considerable star ; not much less than b” 
When the supposed third was pointed out the night before, 
it is said to be smaller than the 1st and 2d satellites. By the 
figure, it did not exceed the distance of the 2d ; and b is called 
a pretty large star. 
Feb. 20, 1792. The 2d satellite, being at a great distance, was 
mistaken for a pretty large star, till about four hours after, 
when its motion along with the planet was perceived. 
“ Feb. 21, 1792. 7 h 3b'. I cannot see the 2d satellite. By 
“ calculation, it should be about 8 °, 6 S.F. and I suspect it to 
“ be there, but cannot get the least assurance.” 
“ March 15, 1792. I cannot see the 1st satellite with 300; 
nor with 480 ; nor with 600.” 
“ March 19. 8 h 33'. I cannot see the 2d satellite with 300. 
“ With 480 I see it very well. I see it also with 800 ; and very 
“ well with.1200. With 2400 and 4800 the satellite cannot be 
iC seen ; but there seems to be a whitish haziness coming on.” 
March 4, 1794. The 1st satellite could not be seen.
