be earlier than the Calculation, I, for fome time 
before that, with my 24 Foot Tube dire&ed to the 
Sun, kept my Eye fixed on that Part of his Limb 
where the Planet was to enter, as fteadily as I could 
for the Wind, which then blew frefii. This Precau- 
tion was not needlefs; for, at 4 h , 54', 59", I per- 
ceived that Mercury had made an Impreflion on the 
Sun’s Limb j by the Quantity of which I concluded,

very little later than this; for I prefently after faw 
him fairly within the Sun. Upon which, I repaired 
to my Quadrant; but this being at my Lodgings, at

continued them till Sun-fet, excepting when I was 
interrupted by the Clouds; and 1 obferved fometimes

found it moft convenient. It will be needlefs, I
