The Abstract of the Operation in finding the true Hour by the Moon according to the late Example.
AS for the Almanac, there are three things (we see) it informs us of, viz. 1. The Hour when the Moon came to her last Cardinal Point. 2. How many days she is going from the said Point to the next; and, 3. In which Days Journey she is at present. Knowing then, according to the late Example that the Moon will be eight days running throu' her Quarter, and that she is in the fourth Days Voyage; 'twill follow that the fourth day in the Table (whose title is eight dayes) will tell you that her present Elongation from the Sun is three hours; so that the Lunar-hour being two in the afternoon, the true hour must be just five at night; only twice two Minutes are to be abated, because she lacks 2 hours from compleating her said fourth days voyage; for your Almanack▪ (according to our supposition) in∣forming you that it was seven at night when she set out from her last Cardinal Point, it must be still seven at night before she compleat's any whole day's Journey during that Quarter.
This then is the summ of the whole Business, nor need you trouble your self with any other Reflexion unless it be to add six hours (as I already said) to the Elongation, in case she be go∣ing from her first Quarter to her Full, or from her Last to her Conjunction. And to conclude take notice, that the hour (if you see the Moon,) may be as well found by day as by night, for her Place on the Globe (which the third Operation show's how to find) is always the true Lunar hour.
