ing the pores of the skin with a liquor,
afforded a passage through that liquor that fills the pores into the
ambient fluid, and thereby the body comes to be discharged.

So that 'tis very evident, there may be a good as well as an evil
application of this Principle. And the ingenious Invention of that
Excellent person, Doctor _Wren_ of injecting liquors into the veins of an
Animal, seems to be reducible to this head: I cannot stay, nor is this a
fit place, to mention the several Experiments made of this kind by the most
incomparable Mr. _Boyle_, the multitudes made by the lately mention'd
_Physician_ Doctor _Clark_, the History whereof, as he has been pleas'd to
communicate to the _Royal Society_, so he may perhaps be prevail'd with to
make publique himself: But I shall rather hint, that certainly, if this
Principle were well consider'd, there might, besides the further improving
of Bathing and Syringing into the veins, be thought on several ways,
whereby several obstinate distempers of a humane body, such as the Gout,
Dropsie, Stone, &c. might be master'd, and expell'd; and good men might
make as good a use of it, as evil men have made a perverse and Diabolical.

And that the filling of the pores of the skin with some fluid _vehicle_, is
of no small efficacy towards the preparing a passage for several kinds of
penetrant juices, and other dissoluble bodies, to insinuate themselves
within the skin, and into the sensitive parts of the body, may be, I think,
prov'd by an Instance given us by _Bellonius_, in the 26. _Chapter_ of the
second Book of his _Observations_, which containing a very remarkable Story
I have here transcrib'd: _Cum Chamaeleonis nigri radices_ (says he) _apud
Pagum quendam Livadochorio nuncupatum erui curaremus, plurimi Graeci &
Turcae spectatum venerunt quid erueremus, eas vero frustulatim secabamus, &
filo trajiciebamus ut facilius exsiccari possent. Turcae in eo negotio
occupatos nos videntes, similiter eas radices tractare & secare voluerunt:
at cum summus esset aestus, & omnes sudore maderent, quicunque eam radicem
manibus tractaverant sudoremque absterserant, aut faciem digitis
scalpserant, tantam pruriginem iis locis quos attigerant postea senserunt,
ut aduri viderentur. Chamaeleonis enim nigri radix ea virtute pollet, ut
cuti applicata ipsam adeo inflammet, ut nec squillae, nec urticae ullae
centesima parte ita adurent: At prurigo non adeo celeriter sese prodit.
