Auouft 26, A broad belt much inclined ; With 200, 250, 
•500, 400, faint appearances of a fecond and of a 
third belt. 
27, The belts lefs inclined. 
Sept* 2, A darkifh belt, but very little inclined ; and a fine 
white belt, clofe to the ring, 
5, The belt a little inclined. 
6, The belt not inclined. 
_ 8, The bright belt clofe to the ring, and two dark equa- 
torial belts. 
It will not be neceffarv to continue the account of thefe 
belts up to the prefent time; but I have conftantly obferved 
them, and found them generally in equatorial fituations, though 
now and then they were otherwife. 
We may draw two conclufions from what has been reported. 
The firft, which relates to the changes in the appearance of 
the belts, is, that Saturn has probably a very confiderable atmo* 
fphere, in which thefe changes take place ; juft as the alteia- 
tions in the belts of Jupiter have been fhewn, with great pro- 
bability, to be in his atmofphere. This has alfo been con* 
firmed by other obfervations : thus, in occultations of Saturn s 
Satellites, I have found them to hang to the difk a long while 
before they would vanifh. And though we ought to make fome 
allowance for the encroachment of light, wnereby a fatellite 
is feen to reach up to the difk fooner than it actually does, 
vet, without a confiderable refraction, it could hardly be kept 
fo long in view after the apparent contaCt. The time of 
hanging upon the dilk, in the feventh fatellite, has actually 
amounted to 20 minutes. Now, as its quick motion during 
that interval carries it through an arch of near fix degrees, we 
find, that this would denote a refraClion of about two feconds, 
provided
