An Example.

WHen the Moone is 10. daies old, I desire to know•• at what houre the commeth to the south southeast to make full Sea at Callis, or in any other place where it floweth on that point•• •• say then 10 daies of her age shew∣eth her to bee 10. pointes, and three times ten minutes from the sunne and behinde him. Now for seeking of the houre of the full sea, the Moone being at south southeast, you must reckon the Sunne to be 10. pointes, and 30. min. before her to the westwardes, which falleth on the west point, and 30. minutes to the Northwards. And therefore the Sunne being on that point, and 30. minutes to the northwards of the west, I say the full Sea shall be at sixe of the clock and 30 minutes at Callis, and in all other pla∣ces where a south southeast Moone makes a full sea.
