use of very high magnifying powers. With 300, however, 
I have a glimpse of what I suppose to be the two large satel- 
lites. A haziness coming on will not permit the angle of posi- 
tion to be taken. 
I The first was 47 0 sf : distance 478 ; the second was 56° 
np; distance 509. They were therefore both visible. 
1809, May 12, n h o'. I viewed the planet with 300, but 
could not perceive the satellites. The planet is too low, and 
there is a strong twilight. 
J The first satellite was 72 £ 0 sp ; distance 578. The se- 
cond was 53 0 np ; distance 529. 
1810, Mav 25, io h 40'. I viewed the Georgian planet 
with the 40 feet telescope, power 400. The disk of it is very 
bright. Several small stars are near it, but without a series 
of observations, it cannot be possible to ascertain which of 
them are satellites. What I suppose to be the second is 65° 
or 70° nf. 
J The first was 87^° np; distance 594. The second was 
76° np; distance 588. Both satellites were therefore visible, 
but being among surrounding stars, could not be distinguished 
from them. 
Investigation of several particulars deduced from the foregoing 
observations , with an exposition of the method by which they 
have been obtained. 
The first use to be made of the numerous angles of position 
that have been taken, must be an investigation of the place of the 
node, and the inclination of the orbits of the satellites. When 
these two particulars are obtained, the times of the periodical
