thence alfo may proceed the non-appearance of any Clouds 
raiffed there* or oflmy Vapors conhderable enough to be 
feen , as there are railed upon this Earth , and that this ab- 
fence of Vapors is perhaps the caufe, that no Crepufcle is 
there , as it fee ms there is none , my felfe at leaft not ha- 
ving hitherto been able to difcerne any mark thereof : For , 
me thinks, it is not to be doubted, but that the reputed Ci- 
tizens of the Moon might fee our Crepufcle 5 tlnce we (ee, that 
the fame is without comparifon ftronger, than the Light afb
