Diurnal Method of Parallaxes.—Finding the parallaxby means of the daily revolution of the earth is… … Figure 15. The difference of these distances from the fixed star,allowance being made for the moons own motion andrefraction, will give the moons horizontal parallax. The moons horizontal parallax being known, to findits distance is, as already mentioned, solely the solution Celestial Measurements.…
