(' 15 ® ): 
from behind the Moon, now here, now there, on all Sides; 
but more efpecially on the Weftern Side a little before the 
Emerfion : And about two or three Seconds before it, 
on the fame Weftern Side where the Sun was juft coming 
out, a long and very narrow Streak of a dusky but 
ftrong Red Light feemed to colour the dark Edge of the 
Moon; tho’ nothing like it had been feen immediately af- 
ter thelmmerfion, But this inftantly vanfthed upon the 
firft Appearance of the Sun, as did alfo the aforefaid lu- 
minous Ring. 
As to the Degree ofDarknefs, it was fuch that one might 
have expededto have feen many moreStars than I find were 
feen at London : The three Planets, Jupiter , Mercury and

of our Atmofphere as was above the Horizon and was 
without the Cone of the Moon’s Shadow, was more or 
lefs enlightened by the Sun’s Beams ; and its Refledion 
gave a difFufed Light which made the Air feem hazey, 
and hindred the Appearance of the Stars. And that this 
was the real Caufe thereof, appears by the Darknefs being 
more perfed in thofe Places near which the Center of the 
Shade paft, where many more Stars were feen, and in 
fome not lefs than Twenty ; though the Light of the Ring 
was to all alike. 
During the Time whilft the Sun recovered his Light, fe- 
veral Altitudes were taken to examine the Regularity of
