to your felf , give fome general account of my prefent imper- 
fect and undigefted thoughts. 
I conlider therefore^ that in the Tides, or the Flux and Re- 
flax of the Sea,befide3 extraordinary Extravagancies.or Irregu- 
larities, whence great Inundations or ftrangly high Tides do 
follow, ( which yet perhaps may prove not to be fo raeerly ac- 
cidental as they have been thought to be^ but might from the 
regular Laws of Motion,ii well coufidercd ^ be both well ac- 
counted for,and even foretold^ ) There arethefe three noto- 
rious Obfervations made of the Reciprocation of Tides, Ftrft^ 
the D/W;W Reciprocation i whereby twice in fomewhat more 
than 24. hours, we have a Flood and an Ebbs ; or a High-wa- 
ter and Law-water. Secondly, th^ Men fir ml ; whereby in one 
Synodical period of the MooLi^fuppofe from Full-moon to Full- 
moon, the Time of thofe Diurnal Viciffirudes doth move round 
through the whole compafs of the i^ux^i^-esv^ or Natural day of 
twenty four hours : As for inflancey'f at the Full-moon the full 
Seabeatfuch orfuchaplace juftatNoon ^ it {hall be the next 
day ( at the fame place ) fomewhat before One of the clock ^ 
the day following, between One and Two ; and fo onward, till 
at the New-moon it fliall be at midnight | (the other Tide, 
which in the Full moon was at midnight,now at the New-raoon 
coming to be at noon 5 J And fo forward till at the next Full- 
moon 5 the FullJea fliall T at the fame place) come to be 
at Isloon again: Again, That of the Spring-tides and Neap- 
tides (as they are called j ) about the Full-moon and New- 
moon the Tides are at the Higheft, at the Quadratures the 
Tides are at the Loweft : And at the times intermediate, pro- 
portionably. Tbirdly^thQ Annual ; whereby it is obferved,ihac 
at fometimes of the year, the Spring-tides are yet much higher 
than the Spring-tides at other times of the year : Which Times 
are ufually taken to be at the Spring and Aurumnc ; or the two 
JEquinoxes; but 1 have reafon to believe (as well from my 
own ObfervationSj for many years, as of others who have b.^en
