, singuli variis faciei locis cutem adeo
inflammatam habere caepimus ut tota sanguinea videretur, atque quo magis
eam confricabamus, tanto magis excitabatur prurigo. Fonti assidebamus sub
platano, atque initio pro ludicro habebamus & ridebamus: at tandem illi
plurimum indignati sunt, & nisi asseverassemus nunquam expertos tali
virtute eam plantam pollere, haud dubie male nos multassent, Attamen nostra
excusatio fuit ab illis facilitus accepta, cum eodem incommodo nos affectos
conspicerent. Mirum sane quod in tantillo radice tam ingentem efficaciam
nostro malo experti sumus._

By which observation of his, it seems manifest, that their being all
cover'd with sweat who gather'd and cut this root of the black _Chameleon_

seems the like circumstance had not been before that noted, nor do I find
any mention of such a property belonging to this Vegetable in any of the
Herbals I have at present by me.

I could give very many Observations which I have made of this kind, whereby
I have found that the best way to get a body to be insinuated into the

Principle lies the great mystery of staining several sorts of bodies, as
Marble, Woods, Bones, &c. and of Dying Silks, Cloaths, Wools, Feathers, &c.
But these being digressions, I shall proceed to:

There is a certain Down of a Plant, brought from the _East-Indies_, call'd
commonly, though very improperly, _Cow-itch_, the reason of which mistake
is manifest enough from the description of it, which Mr. _Parkinson_ sets
down in his _Herbal_, Tribe XI. Chap. 2. _Phasiolus siliqua hirsuta; The
hairy Kidney-bean, called in _Zurratte_ where it grows, Couhage: We have
had_ (says he) _another of this kind brought us out of the _East-Indies_,
which being planted was in shew like the former, but came not to
perfection, the unkindly season not suffering it to shew the flower; but of
the Cods that were brought, some were smaller, shorter, and rounder then
the Garden kind; others much longer, and many growing together, as it were
in clusters, and cover'd all over with a brown short hairiness, s
