Note. Tho' the 2 mean Anomalies answering the 2 Places of the Moon should be, on account of an Error in the Apogee, half a Degree wrong in their Distance, yet that will not cause an Error above 2 or 3 Seconds of Time on the the Sum of the horary Motions; and tho' the Error were 60 Seconds or a Minute, that makes but an Error of 15 Miles, and the Act of Parliament allows an Error of 60 Miles. So that if the Sum of the horary Motions be right to 4 Min. of Time, he hath a good Title [[?]] to the Premium. 
     But because the Moon may be sometimes near 90 Deg. from the Node (and she cannot be more) in which case the horary Motions may be too many to be added, therefore having found her Place as a known Longitude, suppose on [[underlined] Dec. [[/underlined]] 10, at 8 o'Clock, If I add her periodic Revolution (rectify'd from the Place of Earth, the Apogee, and Node) I shall have her in the same Place again in [[underlined] January [[/underlined]] at a certain Time, and if to that Time I add her periodic Revolution rectify'd, I shall have here there again at another Time in [[underlined] February [[/underlined]], and so throughout the year. And having found her Place likewise the 12th of [[underlined] Dec. [[/underlined]] at 9 o'Clock, I add her Period again, and I have her in [[underlined] Jan. [[/underlined]] at another Time, and so in [[underlined] Feb. [[/underlined]] throughout the year. A Table being thus made of her Place and Time, if I find her at Sea in any of those Places, or near them, Then as her horary Motion is to the Difference of your Place and that in the Table, So is an Hour to a 4th to be added or subtracted to the Time in the Table (according as you are short of or exceed the Place in the Table) and you have the Hour at the known Longitude. Thus there is no need of the Equations of the Moon's Center, and of the Variation, or the 6th and 7th Equa-
