Ac 1 7 h . ^9'. theEclipfe was thought to be ended ; and 
was vifibly fo at i7 h . 41': But by comparing the laft 
Obfervations of the Chords between the Horns, it follows 
that the true End of the Eclipfe was at 17 1 ). 38'. 20", At 
i7 h . 4 ) the Moon’s Diameter was 33'. 40'. 
The Middle cannot be fuppofed to be very accurately 
determined by thefe Obfervacions, which were *not fuffi- 
ciently diftant from the time of the greateft Obfcuration. 
However by comparing feveral of them together, the 
Middle will be obtained, viz.

By reafon of Clouds I could not fee the Beginning of 
theEclipfe, nor make fuch Obfervations of the Moon’s 
immerging into the Shadow as I did of her emerging out 
of it. 
By Obfervation 11. compared with Obfervation ry* 
the Digits Eclipfed were 8;-. 
The Angles weremeafured by a Micrometer in a iy Foot 
Telefcope. I have not confidered how far they are confi- 
ftent with one another ; they being fet down here exa&ly 
as they were firft taken. 
This Eclipfe is the more confiderable, as happen- 
ing very near the Moon’s Perigee, and therefore ufeful to 
verify her Anomaly ; as alfo to limit the greateft Diame- 
ter of the Shadow of the Earth, and confequently the 
Parallax of the Moon. This may very properly be com- 
pared with that of the 19th of Ottober , 1697, whole mid- 
dle was at 7 11 . 41'. P. M. at London , and Quantity the 
fame as now.
