of the Georgian planet . 30 9 
1787, February 16, 9 h 3s'. The two satellites are in the 
places where I had drawn them on paper. With a power of 
300, and a wire for the parallel in the focus of the eye glass, 
the first satellite is, by very accurate estimation, about 5 de- 
grees north following; at the same time, and with the same 
power and accuracy, the second is about 3 degrees south fol- 
lowing. A third supposed satellite is pointed out. 
J The position being so near the parallel, and by calcula- 
tion also near the conjugate axis of the elliptical projection of 
the orbits, and therefore less liable to an error arising from 
the application of correction, have been fixed upon as standards 
for the calculation of the periodical revolutions of the satel- 
lites. The supposed third was next evening observed to 
remain in its place. 
1787, February 17, 7 h 58'. I tried to measure the distance 
of the second satellite from the planet by a lamp micrometer. 
The lucid points were 246,4 inches from the eye, and when 
they were 14,4 inches from each other, I found that the 
adjustment of the distance, and angle of position could not 
be made to my satisfaction by an assistant, and gave up the 
measure. The magnifying power being 137, the opening of 
the points gives the angular distance T 17"; but the measure 
when given up was still much too large. 
J The satellite was 284- 0 nf, and the distance 505. 
1787, February 19, 7 h 53'. Having delineated the situation 
of the satellites on paper, I found them in the expected situa- 
tion. A third and fourth were added in the configuration. 
J The first satellite was 58° np ; the second was 82° nf. 
The supposed third and fourth proved to be stars.
