OME time in the beginning of this fummer, Mr. Winflow 
fhewed me a paragraph of a letter from you, requefting 
him, if he could, to obtain the minutes of fome obéervations 
of the eclipfe of the fun, which happened the 27th of October, 
1780. lam fo unfortunate as not to have:any kind of appa- 
ratus for obfervations of that fort ; nor is there, that I know 
of, in this place, any thing of the kind,—thefe things, how- - 
ever ufeful, as well as pleafing, being very little attended to in 
this place. 
Since the faid application from Mr. Win/low, I have received 
from my friend, Do&or Yoġz Clarke, who was educated in your 
College, fome minutes of an obfervation of the fore-mentioned 
eclipfe, made by himfelf and a Mr. Wright, at Charlotte-town, 
on the ifland of Sz. Yobn, in the gulph of Sz. Laurence. 1 
take the liberty to inclofe you a copy of them. © ; 
Dr. Clarke fays, that the obfervation was made with a reflect- 
ing telefcope, two feet long; and compleatly fitted for the pur- 
pofe. A clock was regulated with great accuracy, by means 
of double altitudes of the fun, taken on feveral days before and 
on the day of the eclipfe. The obfervers were deficient only 
in a micrometer to o mntafore the antiy, They eftimated it at
