342 Dr. Herschei/s observations of the satellites 
following ; but a line from the second drawn through the 
planet, leaves the first satellite on the following side. 
J The first was 85^° sp ; distance 533. The second was 
78^ 0 nf ; distance 599. 
1801, April 17, io h 30'. The first and second satellites 
are in view at great angles north following the planet. There 
is a third satellite at a great angle south preceding ; in the 
configuration it is marked exactly in opposition to the second, 
and at half the distance of the first. Six stars are pointed out. 
J The first satellite was 77^° nf ; distance 598. The se- 
cond was 8i° nf ; distance 586 ; and the third by the confi- 
guration was 8i° sp. 
1801, April 18, io° 2 6'. The first and second satellites are 
in the configuration at great angles north following. The 
six stars of last night are in their places, but I do not see any 
star where the third satellite was marked. 
J The first satellite was65°nf; distance 438. The second 
was 74 0 nf ; distance 578. The third was probably the inte- 
rior satellite at its greatest southern elongation, which cannot 
be visible two days together. The configuration of this even- 
ing, compared with that of the night before, shows by the 
situation of the satellites, that their apparent motion is in an 
inverted direction. 
1801, April 19, io h 24'. The first satellite was not observed. 
I saw the second satellite advanced in its orbit in the inverted 
order. The moon is too bright to make observations on 
additional satellites. 
J The first was nf ; distance 144; invisible. The 
second was 66° nf ; distance 438. 
1808, May 27, io h o'. The planet is too low to admit the
