To the fecond^wlixch concerns matter of Faft in Rumney-Marjb ; 
I fay, that (according to the beft account I can there get, and the 
unanimous confent as well of Fiflier-men and other Water-men, 
as of other Inhabitants,) it is conftant ^ hardly miffing (or very fel- 
dome) any one year (be the weather fair or foul 5) and as well a« 
bout CandUi^afs^ as ^hout AllhalJentide ^ every year, though not 
then fo high : Of which ( though they do not pretend to give a- 
By realbn of it,) I think a Caufe may be very rationally affigned. 
For, if you coniult the Tables of the Inequality of Natural Days 
(which parallel I make ufe of for the Explication of this, ) you 
will find J that about one of the Extreams (in January) the In- 
crcafeand Decreafe of the Natural Days fludiuates very much 5 
Ibmetime increafing , fometime decreafing , according as this or 
that of the two Caufts, thwarting one another^doth prevail: But 
about the other Extream {ixiO&ober^^ it ismuchotherwife; the 
iPtcreafngs and Decreajings going on in a continual courfefora 
long time together. And the fame Caufes, applyed to the bufi- 
nefsofTydes , may very rationally be fuppoftd to produce as 
unequal efFefts* 
Tothe/A;W, That the Sea men at have not obfer- 
vedanyfuchfignalEfFeds about AVhallontide and Candlemas: It 
is very poffible that they have not , and that nothing fignal on 
thofe Coafts ufeth to happen at thofe times : For, I fix that matter 
of Faft principally on Rumney'MarJht{zv\A that it doth there con- 
ftantly happen, I am pretty well out of doubt, ) and do but by 
conjefture extend it to the River of Thames (as having its Mouth 
not far from thofe Coafts,)where yet, I think^ you can be my Wit- 
nefi, that it hath been obferved feveral years to fucceed accord- 
ingly. What variety is on other Coafts, I am not certain;But(froin 
an Account read in the Society in my hearing, about the end of 
the year 1 667.)! underftand that about Chepjiom hridge^and con- 
fonantly, I fuppofe, on the Severne at other places, ) they obferve 
the like to happen about the beginning of March^ and end of Sep' 
t ember ^ (the one zsmxxch before the Vernal, zs the other h after the 
Autumnal Mqxxinox^ like as in our cafe it happens, ) which they 
call by the name oi St, Davids Jiream^ and MichaelmaS'flream 2s 
we do thofe in Rent, Candlemas fiream^md Allhallon-ftrectm: (hnd 
when Sea- men take fo much notice of particular Tydes as to gi ve 
name^ to them^ 'tis a great prefumptioB, t^at it is forfome rem.ir^
