In this observation there was a difference of about a second in the rectifying -
the instrument before and after the observation, which I imagine was
occasioned by a small hair, or somewhat that stuck to the wire at the brass
edge, which I saw, but did not wipe it off till I, took up the plummet, in
order to lie down on the couch; so that I judge the rectification after the
observation was the truest.
y Drac. entering 7 24,7; at cross 7 27,7 [10]; going out 7 25,1;
B. & A. 5 20,5. Hence star 2 7,2.
This I take to be a very good and exact observation.
If we make use of the two numbers at coming in and going out, they will
make the star about a second more south than the middle observation, or
2 7,7 south of the mark.
