7he Anirnadverfiom themfelves. 
MY intention 5s not to argue againfl: that part of the Hypothc- 
fisjthat rtJates to the Common Cef2terof Gravity of the Earth 
and Moon^ and the Diurnal and Men^rual viciHitudes of the 
Tydes, the Authors difcourfe being ( in ray judgment) fo ratio- 
i^al and fatisfaftory as to thofe, that I cannot fee what clear obje- 
ction can be made againfl: it* But that which I would beg his 
leave to except againftj till better reafon convince me, is his opi- 
nion concerning the Annual vicifTuudes , and the true caufsj 
thereof, which he fuppofeth to be quite another thing from the 
Common center of Gravity , namely the Inequality of the l^atu- 
ral Days, For I fear he may be miftaken in the time of the An- 
w^/viciffitudeSj which he contendeth to be ^hcui Al/hal/onticle 
and Candlemas: And the reafons of my fear are thefe ^ 
I. Becaufe, if he dare ftand to the general judgment of Sea- 
men, which I conceive is more to be trufted than that of the In- 
h^h\t2iV[tsoiRumneji marJh^htW\\\ ( 1 dare afl'ure him) find very 
few of our Englifli Seamen of that tiiind, who ufe to fay , either 
thatthe time of the year fignifieth nothing at all, or^ if it do, 
that the higheft Tydes of the year feem to happen rather about 
the Equinoxes, than thofe two other ailigned times, when the Na- 
tural days are longert and fhorteft. 
Whereas he gives an inftanceortwo (pag.276.) of very 
' highTydesin the in Ni?z;e«/ier i66o,and 16655 the truth 
of which we need notqueftion, and of which there are fundry 
other the like inftances in our Enghfl] Chronicles 5 I have reafon 
to believe, that thofe high Tydes proceed from another caufe, • 
than he fuj5pofeth* For Firji^ If that which he fuppofeth , fhould 
be thecaufe, the like high Tydes might be expected every No- 
vember y aud (which is more) they flbould happen as frequently 
zhout F ebruary di"^ zhoMt November '-^ of which yet he gives not 
one inftance. And (which is yet more, and very confiderable) 
though I have perufed throughly that perfeft Colleftion 1 have 
of all the high Tydes in the Thames , that our Chronicles take no» 
ticeof fince the Conqueft^ I can hardly find onefuch high Tyde 
in the Thames in February y or thereabouts. Secondly^ Thofe high 
'^^A^^mthi^ThamesmJ^Qvember^ii we dare credit the London- 
Watermea.
