about five minutes after, at 16^ 30' 51''' mean time, 
a thick darknefs came on the Moon’s upper limb, 
which was fiill difiindtiy to be feen through it. At 
16^ 39' 21''' the limb was broke. The middle of 
the eciipfe was reckoned to be the middle time be- 
twixt the difappearing of this limb, and the re- 
appearing of the other. I likewife fend yon the 
fidereal times, by which the oblervations were taken, 
each obfervation being corrected to lefs than half a 
fecond j the mean times are not fo near, being taken 
from the other by means of a table j but are flill 
corre» 5 t enough for obfervations which, of themfelves,. 
cannot be obferved with great precifion.
