1trary, the Tide is the cauſe of them, that is, of bringing them
into the brains more apt for loquacity and oſtentation, than for
the ſpeculation and diſcovering of the more abſtruſe ſecrets of
Nature; which kind of people, before they can be brought to
prononnce that wiſe, ingenious, and modeſt ſentence, I know it
not, ſuffer to eſcape from their mouths and pens all manner of
travagancies. And the onely obſerving, that the ſame Moon, and
the ſame Sun operate not with their light with their motion, with
great heat, or with temperate, on the leſſer reeeptaces of Water,
but that to effect their flowing by heat, they muſt be reduced to
little leſſe than boiling, and in ſhort, we not being able artificially
to imitate any way the motions of the Tide, ſave only by the
tion of the Veſſel, ought it not to ſatisfie every one, that all
the other things alledged, as cauſes of thoſe eſſects, are
vaine fancies, and altogether eſtranged from the Truth. I
ſay, therefore, that if it be true, that of one effect there is but
one ſole primary cauſe, and that between the cauſe and effect,
there is a firm and conſtant connection; it is neceſſary that
ſoever there is ſeen a firm and conſtant alteration in the effect,
there be a firm and conſtant alteration in the cauſe. And
cauſe the alterations that happen in the ebbing and flowing in
ſeveral parts of the Year and Moneths, have their periods firm and
conſtant, it is neceſſary to ſay, that a regular alteration in thoſe
ſame times happeneth in the primary cauſe of the ebbings and
flowings. And as for the alteration that in thoſe times happens
in the ebbings and flowings conſiſteth onely in their greatneſs;
that is, in the Waters riſing and falling more or leſſe, and in
running with greater or leſſe impetus; therefore it is neceſſary,
that that which is the primary cauſe of the ebbing and flowing,
doth in thoſe ſame determinate times increaſe and diminiſh its
force. But we have already concluded upon the inequality and
irregularity of the motion of the Veſſels containing the Water to
be the primary cauſe of the ebbings and flowings. Therefore
it is neceſſary, that that irregularity, from time to time,
ſpondently grow more irregular, that is, grow greater and leſſer.
Now it is requiſite, that we call to minde, that the irregularity,
that is, the different velocity of the motions of the Veſſels, to
wit, of the parts of the Terreſtrial Superficies, dependeth on
their moving with a compound motion, reſulting from the
mixtion of the two motions, Annual and Diurnal, proper to the
whole Terreſtrial Globe; of which the Diurnal converſion, by
one while adding to, and another while ſubſtracting from, the
Annual motion, is that which produceth the irregularity in the
compound motion; ſo that, in the additions and ſubſtractions,
that the Diurnal revolution maketh from the Annual motion,
into the brains more apt for loquacity and oſtentation, than for
the ſpeculation and diſcovering of the more abſtruſe ſecrets of
Nature; which kind of people, before they can be brought to
prononnce that wiſe, ingenious, and modeſt ſentence, I know it
