30 6 Dr. Herschel’s observations of the satellites 
namely 8of 0 sf ; which agrees sufficiently well with an esti- 
mation made without a direction for the parallel. The sup- 
posed 3d, 4 th, and 5th, by next night’s observation, remained 
in their places as small stars. 
1787, January 18, n h 45'. There are two supposed satel- 
lites ; the first is directly south of the planet ; the second is 
about 45 degrees south following, and a little farther from 
the planet than the first. With 480 the first is about 4 dia- 
meters of the planet distant from it ; the second is about 4^ 
or 5 diameters from the planet ; the first is from the second 
about diameters of the planet. There is no small star in 
the path of the planet that might be taken for a satellite to 
morrow. 
J The first was 7 6f sf. The second was 59^ sf ; both these 
positions agree sufficiently well with the delineated configu- 
ration. 
1787, January 24, n h 23'. The first and second satellites 
of January 18, are no longer in the place in which they were 
that night. There are two satellites ; the first is about 45® 
np the planet ; the second is about 8o° np ; it is brighter than 
the first. I had a glimpse of a 3d and 4th. 
X The first satellite was 49 0 np ; the second was 75^ np, 
which agrees well with the estimations and with the configu- 
ration. The observations of the third and fourth were lost, 
the planet not being seen again till eight days after, when it 
would have taken up too much time to look for them. 
1787, February 4, 6 h 2i # . The first satellite is about 8o° sp; 
the second is about 30° nf. There is too much day-light to 
see the satellites well. A third supposed satellite is south 
preceding the first ; it is extremely small. There is but one
