But of all the Obfervations that have been com- 
mmnicated to me, that of Mr. Long at Longframling- 
ton *, determines the Southern Limit with the greateft 
Exa&nefs. The Annulus, he fays, was very fmall there 
upon the upper Part, and the Duration 40 or 41 half 
Seconds, meafured by a Pendulum 9, 81 Inches long ; 
from which we may conclude, that the Limit was very 
near this Place. This curious Obfervation, with feve- 
ral others, was communicated by Mr. Mark at Dun- 
bar. I have received no Accounts concerning this 
Appearance from any Places on the Weft Coaft of 
England. At Alnwick in Northumberland the Eclipfe 
was Annular, but I have not heard that the Time of its 
Continuance was meafured. 
At Berwick^ the annular Appearance continued 
Betwixt four and five Minutes : The End of the Eclipfc 
.at Dunbar , by Mr. Mark's Obfervation, was at 4 Ho. 
48 Min. 1 6 Sec. but there was fome Miftake com- 
mitted in reckoning the Vibrations of the Pendulum 
in meafuring the Continuance of the Annulus. 
At St. Andrew's, this Appearance was oblerved to 
continue precifely fix Minutes, by a Pendulum Clock, 
by Mr. Charles Gregory and Mr. David Toung , Pro- 
feffors in the Univcrfity. By a Figure of the Annulus 
taken from its Image, projeded through a Telefcope 
upon a Paper Screen, the Breadth towards the South- 
eaft Part of the Sun's Disk is rather more than double 
of its Breadth towards the oppofite Part.
