Hie Conjè&iire;. yet this Phenomenon may admit o f am
other folution, for why may not thofe Creatures be there
generated, and after Hie fall saf thofe Rains defert their
Cells o f L at ebree, tobask upon the furface o f the Ground
as We daily ;fee here in Frogs and Wmns>. and other, jRepv
tilts ?.:However it is, the Ponds that were never ftored
may be fupply’d other ways* for it is/üfaal foir Ee/es to
quit the Pits, and creep into the Graft and Hitches, and this
I have often obforv’d, having found Eeles in the midft of
Fields, remote from any Pit, by which means other Ponds
may be replenifh’d with this kind o f Filh : :for my part I
Ihall not determine the Point, but thefc being induftrious
Ages/ hy the afliftance ö f Microfcopes, which, akte daily

But I cannot here omit that remarkable Experiment of
the moft ingenious Lewenhooke, who in this Creature was
the firft that gave us an ocular Demonftration of the Circulation
of the Blood, and beyond contradiction has made it
manifeft that the Vein and Artery are one continued. Canal,
Shewing a Pulfation in xme p artnf the Veflèï, and none in
the other, but that the Blood ffowly creeping on, the Arteries
at their Extremities form a kind o f Semicircle; fo
that the ftrait Line being terminated, the Syftole o f the
Heart at fo great a diftance is notable to a feft a Gdrye, for
we rauft imagin the Pulfe to be extreamly weak at the
Extremities of the Arteries, for when a Veffd deviates from
the direct Line of the Power, it thence ceafos to be aflfeét-
ed with i t ; and hence it is that the Veins, tho’ they are
continued Veflels with the Arteries, have no Puliation at
all. What is faid of this Fifli generating with fVipers, as
trifling and ridiculous, for whoever examins the Parts of
thefo two Creatures fubforvient to Generation, will find it
wholly impoffible, the Male Viper containing a Tents, and
the Female Ova and Ovaria, but in Eeks neither are- dift
cernible.
