The Second Example.

Eight dayes after the moon hath beene new or at the full, I desire to know when the moone commeth to the south, at Embden, or Enckhuysen, and such like places, makes high water (for there a north and a south moone makes full sea) I seek under the north and south stroke the 8 day in the 1 columne, and by that in the second 6 houres, 24 minut. on that then shall the moone come to the north and south at 6 hour. 24 min. and make high water in that place.

The tyde 48 min. later every day, that is foure or fiv•• parts of an houre, then if you know at what houre the new or full moone make high water in any one place, you shall reckon from that first day every day foure or five parts of an houre later, and so you shall find the just tim•• of high water or full sea in that place.
