Satellites of the Georgium Sidus, & c. 6 1 
turned out, even when I have given up as improbable the ex- 
istence of a supposed satellite seen in that manner, that it has 
afterwards nevertheless been discovered that a small star re- 
mained in the place where the satellite had been suspected to 
be situated. An instance of this may be seen in the report of 
the observations that were made March 21 and 22, 1 794. Be- 
sides, in the present case, it is additionally mentioned, that the 
same object was examined with a power of boo, which conti- 
nued the suspicion. 
From the assigned place of this satellite, at^-of the distance 
of that of the first, it appears that this observation belongs to 
the interior satellite of Jan. 18, 1790, which has already been 
examined. The 1st satellite was this evening at its greatest 
elongation, one-third of which is about 11". The apogee dis- 
tance of a satellite whose greatest distance is 16", 1 would have 
been 6", 1 on the day of our observation; but, not being come to 
the apogee, by many degrees, it could not be so near the planet. 
For the sake of greater precision, let us admit that the satel- 
lite was exactly south following ; that is, 45 degrees from the 
parallel, and 45 from the meridian; then, by calculation, a 
satellite whose orbit is at i6",i from the planet, would, in the 
situation now admitted, have been 7",i from its centre, which 
might coarsely be rated at i of the distance of the first. But 
the estimation of 11" is probably more accurate than that in 
the 1st observation, where 2 diameters are given. And, by 
calculating from this quantity, we find that the greatest elonga- 
tion distance of the satellite is 25", 5 ; now, putting 2^ diame- 
ters in the first observation, instead of 2, the distance deduced 
from it will come out 19", 3; which is certainly an agreement
