down the Times o£ the Other, and the two Ebbs intervening, by fubdividing 
the Differences, he afsignes between two Tides, equally amongft them. In 
all which, though there may be Errors, that is not to be eonfidered, feeing 
the Diffeiais to Correft and State the Times of the Tides exaUlj by Expert 
ments, after this method. Mr. wing ftates the High waters to fall out at 
London- Bridie conftantly, when the Moon is 4 6* deg, 30, min. to the 
Weft- ward ot the Meridian , For the Times ,he marks for them, are made 
op by adding every day 3. hours, 6 minutes, to thole in his Table for know- 
ing the Time of the Moons coming to the South. 
\ The Fir ft Table confifts of tVc>o Parts, and each part ofjW Columns. 
The fir ft part marks the Tides and Ebbs from the day of the iVcw-Moon to 
i ts Full : The other , from the Full to the next New, The firft Column in both 
parts hath the day of the Month and Week ; M. Handing every where for 
Morning , and A. for Afternoon. The third Column, hath the Character 
of the day of the Week prefixt to the Hour and Minute of the High-water, 
md anfwefingto the day of the Month. The /^/Column hath the fame for 
the time of Low-water, varying the Character of the day, as often as the 
Low-water falls out more early than the High-water. In this Example be- 
tween the fold New Moons there falls out in all juft 57, periods of the Tide 
or Flowing water, and 5 8. of the Ebb or Low- water • which numbers vary 
according to the Intervals of the Moons changes ; but with what conftancy 
and exadmefs, is to be inquired after : Which whofoever undertakes to do, 
may keep luch a Table , as is here propofed, in a Book by it felf, 
T he Other Table doth in 9. Columns comprehend the particular Obferva- 
tion$ of the Degrees of the Rifing and falling of the Tides, and the other 
things fpecified at the Tops of them : The firfi Column marking the Hour 
m.d Mi nut common to all the feverai Obfervations. Each hour is divided in 
3 , equal Parts, 1 hat nu mber of Obfervations being only pitchYupon by way 
of Example : The numbers may elfe be varied at pleafure, when other more 
frequent Obfervations are thought fit to be made, or when they prove too 
frequent and laborious • though the moft frequent are moft definable till 
competent information of all particulars be attained, * 
The Rifng of the Tide from Low- water to the higheft pitcht of the Full 
Sea, is here fuppofedto be 60. foot: And the Degrees of its rifing every 20. 
■ Minucs, to be in the Froportion of Signes , The whole time of Flowing fup- 
pofed to be 6. hours. But this Example will ferve for marking the Spaces of 
the Increasing or R ifing, as well as of thefalling of the water, in order to the.ir> 
veftigation of their Proportions to one another, when the Duration of the Tide 
exceeds 6, hours by any number of minuts, as well as for juft 6 . hours - 
feeing they may be eafiiy colleded from any Number of Obfervations their 
precileTime and that of the Duration of the waters Rifing and Falling^ that 
is, the juft interval between the High-water and Low- water) being known * 
This Calculation l>y Signes being only fet down as a Conjecture, flowing
