through all _pellucid_ or perfectly _homogeneous_ Bodies; Or the more
_gross_ and _vibrative Pulse_ communicated through the _Air_ and all other
convenient _mediums_, whether fluid or solid: Or the _effluvia_ of Bodies
_dissolv'd_ in the _Air_; Or the _particles_ of bodies _dissolv'd_ or
_dissoluble_ in _Liquors_, or the more _quick_ and _violent shaking motion_
of _heat_ in all or any of these: whatsoever does any wayes promote any of
these kinds of _criteria_, does afford a way of improving some one sense.
And what a multitude of these would a diligent Man meet with in his
inquiries? And this for the helping and promoting the _sensitive faculty_
only.

Next, as for the _Memory_, or _retentive faculty_, we may be sufficiently
instructed from the _written Histories_ of _civil actions_, what great
assistance may be afforded the Memory, in the committing to writing things
observable in _natural operations_. If a Physitian be therefore accounted
the more able in his Faculty, because he has had long experience and
practice, the remembrance of which, though perhaps very imperfect, does
regulate all his after actions: What ought to be thought of that man, that
has not only a perfect _register_ of his own experience, but it grown _old_
with the experience of many hundreds of years, and many thousands of men.

And though of late, men, beginning to be sensible of this convenience,
have here and there registred and printed some few _Centuries_, yet for the
most part they are set down very lamely and imperfectly, and, I fear, many
times not so truly, they seeming, several of them, to be design'd more for
_Ostentation_ then _publique use_: For, not to instance, that they do, for
the most part, omit those Experiences they have made, wherein their
Patients have miscarried, it is very easie to be perceiv'd, that they do
all along _hyperbolically extol_ their own Prescriptions, and vilifie those
of others. Notwithstanding all which, these kinds of Histories are
