nse is
not able to distinguish, are manifested. This is oftentimes further
promoted also by the help of _Burning-glasses_, and the like, which collect
and unite the radiating heat. Thus the _roughness_ and _smoothness_ of a
Body is made much more sensible by the help of a _Microscope_, then by the
most _tender_ and _delicate Hand_. Perhaps, a Physitian might, by several
other _tangible_ proprieties, discover the constitution of a Body as well
as by the _Pulse_. I do but instance in these, to shew what possibility
there may be of many others, and what probability and hopes there were of
finding them, if this method were followed; for the Offices of the five
Senses being to detect either the _subtil_ and _curious Motions_ propagated
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
