This day the air was very clear, and the stars appeared very distinct and
bright, and moved steady; y Drac. was so bright as plainly to be seen several ¬
times (at once) on both sides of the wire. The wind blowed pretty
briskly from the north-east, and we had constant moist and rainy weather
for a week or ten days before this day; so that 1 imagine that the difference
of the adjusting the mark before and after was owing to the alteration in
the chimneys; for about 15’ before the observation, index stood at 7 6,7 ;
and a quarter of an hour after the observation, at near 9 0,0; so that in
30’ it varied near 1’ 1".
N. B. I had dropped down paper both before and after the observation,
so that this could not be owing to cobwebs, as is evident likewise from the
gradual alteration, it continually increasing all the time I observed it.

I scarce ever saw any star flutter so much as this did.
I looked out, but
could not perceive any thing more than ordinary in the air; but it soon
after grew very foggy.
