Dr. Herschei/s Observations on the 
Supposing the satellite now to be not far from its greatest 
elongation, I measured the declination between the centre of 
Saturn, and the 5th satellite ; causing one to pass along one 
wire, while the other followed upon the other wire.

1' 43", 749 mean of the two 
measures. 
Not being satisfied with the considerable disagreement, I 
took another measure with the utmost precaution and care ; 
as the apparent curvature of the wires at so great a distance, 
required more than common attention.

the parallel of Saturn. 
The satellite not being perhaps arrived at its greatest elon~ 
gation, I took six other measures of its distal

In the last six measures of the 5th satellite, I used a method 
a very little different from that which I employed before, and 
which is probably more accurate. I used to observe, when the
