Emerfion was about Ten Degrees below the Horizontal 
Line through the Moon’s Center on the Weft fide ; and at 
14 Minutes paft Nine, correct Time, I judged the Horns 
of the Eclipfe to have been exacftly perpendicular, and by 
confequence, the Centers of the bun and Moon to be in 
equal Altitude. 
It was univerfally remarked, that whenthe laftpartof 
the Sun remained on his Eaft fide, it grew very faint, and 
was eafily fupportable to the naked Eye, even through 
the Telefcope, for above a Minute of Time before the to- 
tal Darknefs; whereas on the contrary, my Eye could 
not endure the Splendour of the emerging Beams in the 
Telefcope from the firft Moment. To this perhaps two 
Caufes concurred ; the one, that the Pupil of the Eye 
did necefiarily dilate it felf during the Darknefs, which 
before had been much contra&ed by looking on the Sun. 
The other, that the Eaftern parts of the Moon, having 
been heated with a Day near as long as Thirty of ours, 
could not fail of having that part of its Atmofphere re- 
plete with Vapours, railed by the fo long continued a< 2 ion 
of the Sun ; and by confequence it was more denfe 
near the Moons Surface, and more capable of obftruding 
the Luftre of the Sun’s Beams. Whereas at the fame time 
theWeftern Edge of the Moon had fuffered as long a Night, 
during which there might fall in Dews all the Vapours 
that were raifed in the proceeding long Day ; and for that 
reafon, that part of its Atmofphere might be feen much 
more pure and tranfparent. But from whatever caufe it 
proceeded, the thing it felf was very manifeft and noted 
by every one. 
About two Minutes before the Total Immerfion, the re- 
maining part of the Sun was reduced to a very fine Horn, 
whole Extremities leemed tolofe their Acutenels, and to 
become round like Stars. And for the Space of about a 
Quarter of a Minute, a fmall Piece of the Southern Horn
