aded, that
that must needs be in the midst of the Body, as well in regard of
Latitude as Longitude. He proceeded in his search, till at last he found
the Heart, which when he saw closed with a very strong Cover, and
fastned with strong Ligaments, and covered by the Lungs on that side
which he had open'd; he began to say to himself. "If this part be so on
the other side as it is on this which I have open'd, then 'tis certainly
in the midst, and without doubt the same I look for; especially
considering the Conveniency of the Situation, the Comliness and
Regularity of its Figure, the Firmness and Solidity of the Flesh, and
besides, its being guarded with such a Membrane as I have not observ'd
in any part." Upon this he searches the other side, and finding the same
Membrane on the inside of the Ribs, and the Lungs in the same posture,
which he had observ'd on that side which he had open'd first, he
concluded the Heart to be the part which he look'd for.

tryal and a great deal of pains, he made shift to tear; and when he had
laid the Heart bare, and perceiv'd that it was solid on every side, he
began to examin it, to see if he could find any hurt in it; but finding
none, he squeez'd it with his Hands, and perceiv'd that it was hollow.
He began than to think that what he look'd for, might possibly be
contain'd in that Cavity. When he came to open it, he found in it two
Cavities, one on the right side, the other on the left. That on the
right side was full of clotted Blood, that on the left quite empty.
"Then (says he,) without all doubt, one of those two Cavites must needs
be the Receptacle of what I I look for; as for that on this side there's
nothing in it but congealed Blood, which was not so, be sure, till the
whole Body was in that condition in. which it now is" (for he had
observ'd that all Blood congeals when it flows from the Body, and that
this Blood did not differ in the least from any other,) "and therefore
what I look for, cannot by any means, be such a matter as this; for that
which I mean, is something which is peculiar to this place, which I find
I could not subsist without, so much as the Twinkling of an Eye. And
this is that which I look'd for at first. For as for this Blood, how
often have I lost a great deal of it in my Skirmish
