had fufpeded my telefcope, if I had not known it to 
have been rightly adj ufted. 
At i4 h 22' 4", the preceding part of the ring was 
emerged, and it appeared more bright ; and now the 
body feemed emerging or emerged, but fo very hazy 
and ill defined, both the body and the ring confufed 
together, clofely on the Moon’s dark limb, that I 
ihould not have taken it for Saturn, but for a comet 
emerging from behind the Moon, had I not known 
otherwife from the tables, or feen Saturn the preced- 
ing mornings. 
At 14 11 22' 30", the preceding end of the ring 
more plain and bright, the lubfequent end of the ring 
more dull; and the body, at this time, appeared a 
little more diftindt than before. I continued obferving 
to fee what would follow. 
At i4 h 22' 34", the fubfequent end of the ring 
appeared moft dull, and the preceding end clear; 
after which, in fome ftiort fpace of time, the whole 
ring and body of Saturn appeared fharply and well 
defined. 
Wherefore, I conclude, that this diverfity of ap- 
pearance muft have arifen from the effe&s of an atmo- 
sphere of the Moon.
