hor.par

The minute of sun-rise and sun-set, shown under the hours given on
the first line thus on the 11th, the sun rose at 45m. past 3, and set
at 13m. past 8.

The Equation of time, or difference between the sun-dial and the clock,
or the apparent noon and true or mean noon: thus, on the 3d, the clock was
after the sun 2m 11s; and on the 16th, 19% before it.

The declination of the sun for every day: thus, on the 1st day he had
22° 7′ north declin.

The declination of the moon for every day: thus, she was north until
the 8th, and then, south until the 22nd day.

It is important to observe, that the times specified are those of the
moon's setting from new to full, and those of her rising after being
full.

This column gives the instant at which the moon souths, or comes to the
meridian of Greenwich, for every day.

The horizontal parallax of the moon, as she varies her distance from us whilst
performing her monthly ellipse: thus, we may learn she was in Perigee, or nearest
to us, about the 1st and the 28th, her parallax being then greatest. (See M on p. 18).

The Moon's latitude: thus, from the 5th (when she was in her descend-

ascending node.
