322 Dr. Herschei/s observations of the satellites 
J The first satellite was 70° np ; the second was 4 6|° sp; 
the third was not accounted for. 
1792, March 30, n h 18'. The first satellite by the confi- 
guration is at a great angle sp; the second is at a great 
angle sf. 
J The first satellite was 78^ 0 sp; the second was 83° sf. 
The first satellite (miscalled a star the 27th) is gone from the 
place where it was. 
1793, February 5, 9 0 18'. Neither the first nor second 
satellites are visible. A very small star is 19 0 3' sp. 
J The first satellite was 30° sp ; distance 282 ; the second 
was 23 0 sf; distance 2 45. There is no subsequent observa- 
tion of the small star. 
1793, February 7, 9 h 38'. The first satellite is 79 0 39' sp. 
9 h 20', the second is 39 0 51' nf. The wind being very 
troublesome, the measures cannot be very accurate : The 
difficulty was in finding the parallel.* I viewed the planet 
with 240, 320, 480, 6 00, 800 and 1200, but saw no satellites 
nearer than the two known ones. The north following satel- 
lite being farther from the planet than the south following 
one, I take it to be the second ; the difference of their dis- 
tance appeared plainest with 1200. I viewed the planet also 
with 2400, 3600, 7200. 
J The first satellite was 86£° sp. Distance 590. The second 
was 68£ 0 nf ; distance 313; and supposing the radius of the 
orbit of the first to be to that of the second as 3 to 4, we have 
the apparent distance of the first to that of the second as 177 
to 203. 
* Telescopic vision in windy weather is generally very perfect, and except in cases 
which require an uninterrupted steadiness of the instrument, will admit of the highest 
magnifying powers.
