to the Ring and Saturn^ he found that Beit could not 
' axife from fuch a Caule, 
He fays, that at Times he has feen with this Tele- 
fcope three ditferent Satellites of Saturn^ but could 
never have the Fortune to fee all five. 
Aug. 1723. Mr. Hadley 2 lMs^ that he has feveral 
Times feen the Shadow of the firh, fecond, and third 
Satellites of Jupiter pafs over the Body of that Planet, 
and that he has feen the firfl: and fecond appear, as a 
bright Spot upon the Body of Jupiter., and has been 
i able to keep Sight of them there for about a Qjaarter 
of an Hour, from the Time of their entring on his 
Limb. 
Jupiter's, Satellites have of late Ye irs been fo fitua- 
ted, with regard to the Earth and Jupiter., that he has 
not had fufficient Opportunity of obferving the Tranfit 
of the fourth Satellite, or of its Shadow. 
The dark Line on the Ring of Saturn, parallel to 
its Circumference, is chieiiy vifible on the Anfji., or 
Extremities of the Elliptick Figure, in which the Ring 
appears •, but he has feveral Times been able to trace 
it very near, if not quite round , particularly in May., 
1712, he could difcern it without the Northern Limb 
of Saturn, in that Part of the Ring, that appeared be- 
yond the Globe of the Planet. The Globe of Saturn 
(at leaft towards its Limb) refleds lefs Light than the 
inner Part of the Ring, and he has fometimes diflin- 
guifh’d it from the Ring by the Difference of Colour. 
The dufky Line, which in 1720 he obferved to ac- 
company the inner Edge of the Ring crofs the Dilk, 
continues clofe to the fame, though the Breadth of the 
Ellipfe is corifiderably encreas’d fince that Time.
