My daughter was able to see volume 2 in the rare book room at the
University of Virginia where she copied out the following (looks quite
interesting):

Mackay Vol 2
Tables
I To convert time longitude
II To reduce longitude to time
III Depression of the Horizon
IV Dip of the Sea at different Distances from the Observer
V Correction of the Sun in Altitude
VI Mean Astronomical Refraction

IX Correction of the Moon's apparent Altitude
X To reduce the true altitude of the Sun to its apparent Altitude
XI  " Moon "
XII " Fixed Star"
XIII-XVI To reduce the Declination of the Sun to any given Meridian
and to any given time under that Meridian
XVII For selecting a proper Star from which the Moon's Distance ought
to be observed, that as little as possible of the Moon's proper Motion
may be lost
XVIII To reduce the right Ascension of the Sun to any given Meridian
and to any given time under that Meridian
XIX To reduce the Declination, Right Ascension, Horizontal Parallax,
and semidiameter of the Moon, to any given Meridian, and to any given
Time under that Meridian

Greenwich to the Time of its Transit over any other Meridian

altitude one minute before or after the time of its transit
LXXII For computing the final Effect of Parallax on the Distance
between the Moon and the Sun or a fixed Star

Appendix
1 Containing the Methods for calculating the Time of the Rising of the
Sun, Moon and fixed Stars; the time of the beginning and End of
Twilight

Table A Approx time of Rising / Setting of Sun
B Time answering to a change of Alt of one degree near the horizon

Problem I To find the Apparent Time of Rising or Setting of the Sun
II " of Passage of a Star
III " of the Rising/Setting of a fixed star
IV " of the Moon
V To find the time of beginning + end of twilight and its duration
VI To find time of Shortest Twilight + Duration
VII Given the Lat of a place (between limits 48-32 and 66-32, to find
when it ceases to be night

Notes:  Explains all the tables, has some equations and examples for a
few of them.  includes some plates as well.
