The clock was cleaned in November ; and when fet 
up again, loft, between the 1 8th and 28th, at the 
rate of 7"$ per day. The regulator was then altered, 
and clock fet, and from that time never meddled 
with. 
My obfervatory (if it deferves that name) is a 
room up two pair of ftairs, in a fquare compact 
brick houfe, pretty much expofed indeed to wind, 
from our high fttuation. The face of the clock 
turns due Eaft. I have fet down the throwing-out of 
the pendulum, as judged by the eye, on a fcale 
behind it divided only to every 10 minutes; and 
therefore fome of the variations may only be errors 
in judgment. How far a clock fo fttuated may be 
aftedied by any motion of the houfe in windy wea- 
ther, deferves confideration. I do not however 
perceive that it is, either in the rate or throwing- 
mt.
