39. The Flux and Reflux, or Ebbing and Flowing of the Seas, does conftantly refpect the Motion of the Moon, and in every place when the Moon is on a certain Point of the Compass, or at a certain Distance from the Meridian, it is then High Water at that Place; and fince fhe is twice at the fame Distance from the Meridian, or in two oppofite Points of the Compass, in her diurnal Motion; therefore in moft places there is a double Ebbing and Flowing in a little more than 24 Hours. There has been found by Obfervation, for the most remarkable Coafts, the Points on which the Moon is when it is high Water in each of them; as in the following Table. A Table of the most remakable Sea Coasts, in an Alphabetical Order; fhewing in each of them, the Points of the Compafs, the Moon must be on, when it is bigh Water.

By knowing the Point of the Compass, the Moon is on when it is high Water at any place, we know by Art. 38. the Time fhe takes to move from the Meridian to that Point; and fince we can find by Art. 29. the Time of the Moon's coming on the Meridian any Day; therefore to find the Time of high Water at any place, and on any Day, we have this Rule, viz. To the Hours and Minutes of the Moon's Southing (found by Art. 29.) add the Hours and Minutes anfwering to the Point of Flowing (found from the Table of Art. 38.) the Sum is the Time of full Sea requir'd; countingfrom Noon or Midnight Example. Requir'd the Time of High Water at Bristol Key, on the tenth of May 1731. First, By Art. 29. I find the Moon comes on the Meridian that Day, 48 Minutes paft 12 at Night, then because by the Table in the laft Article, the Moon must be on the Eb S, or Wb N Point of the Compass before it be high Water at Bristol; and fince by the Table at Art. 38. fhe takes 6 Hours, |
