And hence it follows, that whatsoever _Power_ is sufficient to make a Change in this Attraction, or Cohæsion of the Parts, makes an Alteration of the Nature of the Fluid; that is, as the Chymists express it, puts it into a _Fermentation_. And if any one shall think it necessary to enquire into the particular Manner of producing such an Effect, we may perhaps in so abstruse a Matter not improbably Conjecture _thus_, That our Blood consisting chiefly of Two Parts, a simple _Lymph_, and an infinite Number of small _Globules_, containing a very subtle and elastic Fluid, these acute Salts, when mingled with it, do prick those Globules, or _Vesiculæ_, and so let out their imprisoned active Substance, which expanding it self every way, must necessarily be the Instrument of this speedy Alteration and Change (15). From such an _Hypothesis_ as this (and, it may be, not very easily from any other) we may account for many of the surprizing Phænomena in the Fermentations of Liquors; and as precarious as it seems, its Simplicity, and Plainness, and Agreement with the forementioned Doctrine, will, I believe, recommend it before any other to those who are not unacquainted with _Geometrical_ Reasonings. But I wave these Considerations at present, and shall only add One Remark or Two with Relation to the purpose in Hand, and so proceed. In the first place then, we may from this _Theory_, learn, how it comes to pass that so small a Portion of Juice should infect so great a quantity of Liquor; for in order to do this, it is not necessary that the Venom should be at the very first mixt with all its Parts; but it is sufficient that it prick some of the _Bladders_, and the elastic Matter of these being let out, will be a nimble _Vehicle_ to the acute Salts, and not only by its activity disperse them thro’ the Fluid, but restore to them their decreasing _Force_, and thus continue their Effects, till a great part of the Liquor undergoes at least, in some Degree, the like Alteration. And this will the more easily happen in the present Case, because the _Force_ with which this Poison is thrown into the Blood, as appears from the Mechanism of the discharging Organs, is very great, and consequently its Effects will be proportionably violent, or the Mischief more large and diffused.
