318 Dr. Herschel’s observations of the satellites 
J The second satellite was 32 0 sp. The supposed satellite 
was found to be a star. 
1791, February 5, n h 3'. The first satellite is 20° sp. 
io h 43', the second is 6,5° sp. With 6co, third, fourth and 
fifth satellites are marked : but as they are also visible with 
300, they are probably stars. 
J The first satellite was 41 0 sp ; the second was 74-p sp. 
The third, fourth and fifth, were lost for want of subsequent 
observations. 
1791, February 22, 8 h 23'. I cannot perceive the first satel- 
lite, probably owing to its nearness to the planet; I am pretty 
sure the orbits are contracted, so that the planet is approach- 
ing towards their node. 7 h 30', a measure of the position of 
the second satellite is 36° 18' sf. 
J The first satellite was 8^° sp ; distance 333, which may 
account for its not having been seen. The second was 39 0 sf. 
1791, February 23, 7 h 39'. Position of the first satellite 
36° 33' sp. 
J The first was 6o{° sp; the second was nf ; the dis- 
tance was 331, at which the satellite is sometimes invisible. 
1791, March 1, n h 47k The two satellites are in the 
places I had calculated. 
J The first was 73-j 0 np; the second was 20J 0 np. 
1791, March 2, 9 h 18'. The first satellite is hardly to be 
seen ; it seems to be in about the most contracted part of its 
orbit ; the second is only about two diameters of the planet 
from the edge of the disk, but the estimation cannot be very 
accurate, as I am obliged to hide the planet to see the satellite. 
J The first was 37-|°np; its distance 3 77. The second 
was 22~° sp ; its distance 338.
