Times that were marked during the Obfervation.. 
The Latitude of this Place is commonly faid to be 
Degrees yy Minutes s and by fome Trials we have 
made lately, this muft be near the Truth, though in 
fome Maps and Tables it be reprefented greater. By 
comparing an Obfervation we had here of the End 
of the Eclipfe of the Moon, iVw. 20. 1732. with an 
Obfervation of the End of the fame Eclipfe by Mr. 
Graham at his Houfe in Fleetjireet , the Longitude of 
this Place is a little more than 1 2 Minutes of Time

Account afterwards of the Longitude and Latitude of 
this City. 
Some Days before the Eclipfe, the Right Honourable 
the Lord Aberdour fet up a Clock in the Caftle, and 
adjufted it with mine by a Watch that fhewed the Se- 
conds. The Clocks were compared together the Day 
of the Eclipfe at Noon, by a Cannon fired from the 
Caftle, fome Perfons being appointed to attend each 
Clock, and mark the Seconds when they heard the 
Sound : An Allowance of two Seconds and a half be- 
ing made for the Progrefs of the Sound, (which was 
determined by feveral Trials at Night) the Clock in 
the Caftle was found to be before the apparent Time 
12 Minutes 19 Seconds, and fo much is fubdufted 
from the Times that were marked in the Caftle during 
the Obfervation. It was agreed that we fhouLd give 
Signals to one another mutually at the Beginning and 
End of the Eclipfe, and at the Beginning and End of 
the annular Appearance. His Lordfhip's Signal from 
the Caftle was a Cannon, ours from the College a, 
Mufquet, Perfons being appointed to mark our Signal
