At 7 h 5' per clock I took, the altitude of the Sun’s 
centre 1 3 0 49' 55'', from which obfervation the clock 
was 4 feconds of time before the Sun. And the 
fame dav in the afternoon, 
At 4 h 23 per clock, I took the altitude of the Sun’s 
centre 18 0 49' 40" from which obfervation the clock 
was 5 feconds of time before the Sun. 
Thefe and other obfervations confirmed that the 
clock was 5 feconds of time before the Sun at the 
beginning of the eclipfe. 
At S h 45 / per clock, I fet my watch exactly by 
the clocks j captain Bentincke and captain Holland 
were prefent with curious watches. 
From 8 h 45' per clock, to the beginning of the 
eclipfe, I continued obferving with the refle&ing te- 
lefcope, and faw the limb of the Sun through the 
telefcope and thin vapours, without any dark glafs, 
as clearly as it could be feen by any heliofcope 
whatfoever. 
Captain Bentincke pronounced the feconds of time 
as they were fulfilled by the watch, and as the mi- 
nutes of time were fulfilled they were written down. 
At 9 h 4' 29" per watch, I thought I faw a little 
dull tremulous vibration obtrude itfelf on the limb 
of the Sun 5 and, 
At 9 h 4' 30 ' it became a little more fenfible; and. 
At 9 11 4' 31" a little more lenfible ; but it was 
At 9 h 4 7 32" per watch before I was certain the 
Sun’s limb was touched by the limb of the Moon j 
And, 
At 9 15 4' 33 I plainly faw, through this telefcope, 
and the thin vapours of the atmofphere, the lead: vi- 
able dent, perfectly well defined in the Sun’s limb.
