The title of the book, available on this page,
https://archive.org/details/howtokeepclockr01warngoog
is "How to Keep the Clock Right By Observations of the Fixed
Stars with a Small Fixed Telescope and a Little Arithmetic".
Nowadays, of course, what with smartphones setting their time
over the Internet automatically, and various other contrivances
for highly accurate timekeeping being available at little expense for
those who wish to do so, it is unlikely any amateur would feel the
need to set up his very own transit circle.
And, of course, the tables in the book are rather out of date due
to the precession of the equinoxes.
But understanding how a transit circle works - and how it can
work, because the complex Equation of Time affects the Sun's
position, but *not* that of the stars - is of course useful to a
sound understanding of astronomy, as a frequent poster here
is evidence of.

You spend too much time on the science fantasy forums and therefore are too wishy washy to know the difference between checking the accuracy of a clock daily using circumpolar motion as opposed to affirming the planet turns once in 24 hours using theaveraging process expressed by the Equation of Time(keeping).
Stick with what you know if that is all you can manage, but others can do better. The following statement is both crude and false, even though it was the RA/Dec framework by which Sir Isaac tried to rob solar system research of its interpretativequalities-
"... our clocks kept so good a correspondence with the Heavens that I doubt it not, but they would prove the revolutions of the Earth to be isochronical [constant]... " Flamsteed to Moore
The title of the book is fine if all it means is checking the accuracy of a watch of clock, when it overreaches and determines that RA/Dec displaces the 24 hour and Lat/Long systems then it would be bogus.
The guy is too busy sucking on mom's tits for that!!!!!!!

You need a therapist.
