T he cloudy Weather here prevented us from fee- 
ing the Beginning of the Eclipfe, or of total 
Darknefsj but I obferved, pretty exadly, the firft-'- 
Appearance of Light, after the total Darknefs, and 
the End of the Eclipfe , and their refpectivc Times • 
are as follows, visz.

apparent Time. 
Some fmall Time before the renewal of true Light, 
there appeared a remarkable Brightnefs upon the Eaft- 
ern Limb of the Moon, which I am not certain how 
to account for ^ at firft I reafoned with niy fell in 
this Manner* That all the Light which the Moon 
has, during her total Immerfion in the. Shadow, is by 
Rays from the Sun, refraded through the Earth’s 
Atraofphere, and confequently thofe Rays muft be in 
greater Plenty, near the Edge , of the Shadow, than 
near the Axis. But this does not fully anfwer the 
Ph?enomenon, becaufe the Light I fpeak of, was not 
only upon the Moon itfeif, (on whofe Eaftern Limb 
there was a inanifcft increafe of Light, as Ihe ap- 
proached the Edge of the Shadow) but it was alfo 
diffufed about the Edge of the Moon, to a fendble 
2 ' Difiance^
