I viewed the fun with that part of thefe glaffes, which 
was not fmoked, I found the fun white, and a little 
bluifh,. the fmalleft fpots very diftindt, and the difks 
of the fun and Venus much better defined, than I 
could with the other glades ; but the edges of both 
limbs undulating, particularly thofe of Venus. 
Duiing the whole time of my obferving with the 
telefcope, and the Dlue and green glades, I perceived 
a light round about Venus, which followed her like a 
luminous atmofphere, more or lefs lively, according as 
the air was more or lefs clear ; its extent altered in the 
fame manner; nor was it well terminated, throwing 
out, as it were, fome feeble rays on all bdes. When 
I looked through the fmoked part, I faw but badly ; 
by the common fmoked glafs-, yet worfe ; and by the 
black glafs, not at all. 
The interior contaft of Venus with the fun’s limb 
Happened fooner than I expedled, by judging of the 
didances of Venus from the limb of the fun at dif- 
ferent times. As for the lad contadl, I fhould not be 
furprized, if there was a difference of io" or 12' be* 
tween two obfervers, who had indruments and eyes 
of equal goodnefs, and made their obfervations by the 
fame clock ; fo difficult a matter do 1 think it to deter- 
mine the exadt moment. But for the fird, I cer- 
tainly believe, that the difference could fcarce amount 
to more than 2 ." under the fame circumdances. 
However, the following are greater differences for 
the fird contadl, than were expedted :
