PROP. V. The Moon 5 days old, I demand the time of Full-Sea at Rochester, Malden, Blacktail, where S. b. W. Moon is Full-Sea.

Here you may note, That on the Change-day at these Places it flows S. b. W. which is but one Point from the South, being but ¾ of an hour, or 45 min. And it had been all one if it had been North-by-East. Multiply by 4, divide by 5, and the Quotient will be 4; to it add 45 min. S. b. W. shews you it will be Full-Sea at the aforesaid Places at 4 a Clok and 45 min. in the morning. But note, Had it been S. b. E. or N. b. W. it had been 11 ho. 15 min. By this time I hope I have made the Practitio∣ner able to know the time of Full-Sea in any Port, by Instrument and Arithmetick: Therefore I will leave him a small Table for his use.

A TIDE-TABLE.
  H. M.
Rye, Winchelsey, Culshot, a S. b. E. Moon. 11 15
Rochester, Malden, Blacktaile, S. b. W. 0 45
Yarmouth, Dover, Harwich, S. S. E. 10 30
Gravesend, Downs, Blackness, Silly, S. S. W. 1 30
Needles, Orford, South and North Fore-land, S. E. b. S. 9 45
Dundee, St. Andrews, Lisbone, St. Lucas, S. W. b. S. 2 15
Poole, Isles of Man, Dunbar, Diepe, S. E. 9 00
London, Tinmouth, Amsterdam, Rotterdam, S. W. 3 00
Portland, Hartflew, Dublin, S. E. b. E. 8 15
Barwick, Flushing, Hamborough, S. W. b. W. 3 45
Milford, Bridgewater, Lands-end, E. S. E. 7 30
Baltimore, Corke, Severn, Calice, W. S. W. 4 30
Bristol, Start-point, Waterford, E. b. S. 6 45
Falmouth, Humber, Newcastle, W. b. S. 5 15
Plimouth, Hull, Lyn, St. Davids, W. & E. 6 00
Quinborough, Southam. Portsmouth, N. & S. 0 00

Add any two Numbers together of the foregoing Table, and they shall be 12 hours; Except the two last, N, S. and E. W. So that you may perceive, what hath been said from the South, either Eastward or Westward, the same answereth to the North, either Westward or Eastward. And so much for the Tydes. But we will know the Moon's Motion, and the Proportion between Tyde and Tyde.
