320 Dr. Herschel’s observations of the satellites 
J The first satellite was 20{° np ; its distance being 2P3 it 
could not be seen. The second was 62^° nf. 
1792, February 12, 8 h 28'. The first and second satellites 
are in the same line, and I measured their position together, 
it is 88° 19' np ; a supposed third is 84° 23' sp. 
J The first satellite was 86|- 0 np, and its distance 576; 
the second satellite was 83^-° np ; the third proved to be a star. 
] 792, February 13, 8 h 42'. Forty feet reflector, with 360, 
I saw the disk of the planet very well defined. Twenty feet. 
The satellites are advanced in their orbits ; the first is 
drawn much nearer to the planet than it was yesterday ; a 
very small star is 41 0 22' nf. 
+ The first satellite was 56^° np; its distance 389; the 
second was 66-§-° np. The very small star was left in its place. 
1792, February 20, I2 h 57'. The first satellite is 89° 58' 
nf ; 13 11 8', the second is 53 0 21' sf; a supposed third is 
66° if np. 
J The first satellite was 83I- 0 nf ; the second was 53-5- 0 sf. 
By an increase of 25 or 30° in the angle of the third it was 
the same evening proved to be a star. 
1792, February 21, g h 10'. Position of the first satellite 
73° 5%' n P- — 9 h 3°'> I suspected the second satellite to be in 
its calculated place, but even 600 would not verify it. 
J The first satellite was 783- 0 np ; the second was i7-§-° sf; 
distance 292. 
1792, February 26, n h 30'. The position of the first sa- 
tellite is 42 0 49 ' sf. — 8 h 2', that of the second is 73 0 49' np. 
A very small star between the planet and the second satellite 
is pointed out, and another towards the south at double the 
distance of the first is marked in the configuration.
