You may remember, Sir, that, not long before the 
beginning of the eclipfe, the air, from very ferene, 
turned hazy, and thin clouds came from the South- 
weft. I had fet a ftop watch of Graham’s, by a clock 
likewife of his, with which the Sun’s tranfit on the 
meridian was obferved* carefully two days before the 
day of the eclipfe, and the next day after it.. By 
comparing my watch with this clock on my return, 
I found it was 19 feconds too faft in mean time, at 
your houfe, when I obferved the beginning; and 
whereas it then fhew’d 9 h g' i 2 ", it fhould have 
(hewed no more than 9 h 8' 53", from whence fub- 
du&ing 3' 45", the equation of time, there remains 
9 h 5 ' %"> the apparent time of the beginning of the 
eclipfe, as I obferved it. 
But I muft remark, that, the ftate of the fky con- 
tinuing fuch as I have defcribed it, the beginning muft 
have really happened fooner, by 10 or 15 feconds, 
as I judge from the firft perceivable diftance of the 
cufps ; fo that, if I ftate it at g h 4' 53", I prefume I 
(hall err but a very few feconds. 
About the middle of the eclipfe, the air was very 
clear, and the cufps well defined, which wanted a- 
bout 60 degrees of joining. I could not then difcern 
any thing on the Sun about the Moon’s limb, which 
in the leaft indicated a lunar atmofphere. A full di- 
git of the Sun, or more, remained uneclipfed. The 
day-light was but inconsiderably diminifhed, fo that 
neither Jupiter nor Venus could be feen, though both 
in a favourable pofition, to the eaft of the Sun. 
Fahrenheit’s thermometer, placed without door 
to the north, (food at 50 when the eclipfe began, and 
fell but one divifion whilft it lafted.
