eclipfe, the Moon’s body being entirely obfcured, the 
light of the Sun is behind, and comes through the fmal- 
left openings in the difk without any confufion. 
The time elapfed between the firffc appearance of the 
Sun’s body through the aperture of the limb of the 
Moon and the appearance of the limb of the Sun out of 
that of the Moon will ferve to determine the depth of 
the faid chink, aperture, or inequality, which is equal to 
the height of the eminencies which form it. 
The luminous point was towards the North-weft part 
of the Moon’s difk, a little more to the North than the 
part of its limb through which that of the Sun appeared 
at the beginning of the emerlion; and it is remarkable, 
that no other luminous fpeck was perceived in the difk 
beftdes this. This aperture is therefore the only one in 
that part of the difk through which the emerlion was
