The above oblervations were minuted from a flop- 
watch of Mr. Ellicott’s, having no pendulum-clock 
or time-piece. 
The weather being cloudy for feveral days before 
that of obfervation, there was no opportunity of af- 
certaining the error of the watch ; but, on the day of 
obfervation, I found, upon comparing the watch with 
a meridian line in the town-hall, that when the cen- 
ter of the Sun’s image was on the meridian line, the 
time pointed by the watch was 4' 10" pad twelve. 
Comparing the watch the 7th, 8th, and 9th June 
with the meridian line, I found it had gained nearly 
two minutes each day, the time pointed by the watch 
on the 9th June being io' 5", when the Sun was on 
the meridian.
