ht or Heat in it or not. In order to this he took a Wild Beast and
ty'd him down, so that he could not stir, and dissected him after the
same manner he had dissected the _Roe_, till he came to the Heart; and
Essaying the left Ventricle first, and opening it, he perceiv'd it was
full of an Airy Vapour, which look'd like a little Mist or white Cloud,
and putting in his Finger, he found it hotter than he could well endure
it, and immediately the Creature Dyed. From whence he assuredly
concluded, that it was that Moist Vapour which communicated Motion to
that Animal, and that there was accordingly in every Animal of what kind
soever, something like it upon the departure of which Death follow'd.

Sec. 27. He had then a great desire to enquire into the other parts of
Animals, to find out their Order and Situation, their Quantity and the
manner of there Connexion one with another, and by what means of
Communication they enjoy the Benefit of that Moist Vapour, so as to live
by it. How that Vapour is continu'd the time it remains, from whence it
has its Supplies, and by what Means its Heat is preserv'd. The way which
he us'd in this Enquiry was the Dissection of all sorts of Animals, as
well Living as Dead, neither did he leave off to make an accurate
Enquiry into them, till at length he arrived to the highest degree of
Knowledge in this kind which the most Learned Naturalists ever attain'd
to.

Sec. 28. And now he Apprehended plainly that every particular Animal, tho'
it had a great many Limbs, and variety of Senses and Motions, was
nevertheless _One_ in respect of that Spirit, whose Original was from
one firm Mansion, _viz_. the Heart, from whence, its Influence was
diffus'd among all the Members. And that all the Members were
subservient to it, or inform'd and supported by it, and that this Spirit
made use of those Members, in the same manner as a Soldier do's of his
Weapons, or an Huntsman or Fisherman of his Tackling, who makes use of
different ways and things, according to the difference of the Creatures
he intends to catch. Now the Soldiers Weapons are some of 'em defensive
and offensive, and the Sportsman's too are some for Land, and some for
Water: So the Anatomists Instruments, are some for Fission, others for
Fraction, and others for Perforation. And thus tho' the Body was _One_,
yet that governing Spirit made use of it several ways, according to the
respective uses of each Member, and the several ends which it propos
