But not to engage any farther in these sort of Controversies, we may perhaps from the foregoing Observations receive some Light in order to understand the Nature and Reason of all those Symptoms which attend the Bite of this Creature. For the pungent Salts of this Venom, when with Force thrown into the Wound, will not only as so many _Stimuli_, irritate and fret the sensile Membranes, whereupon there necessarily follows a greater Afflux than ordinary of the Animal Juices that way, (as is manifest from the _Bellinian_ Doctrine, _De Stimulis_) so that the wounded Part must be Swelled, Inflamed, Livid, _&c._ but also these _Spicula_ being mixt with the Blood, will so disjoin and disunite the Parts of it, that its Mixture must be quite alter’d; and from the various _Cohæsion_ of its _Globules_ will arise such different Degrees of _Fluidity_ and _Impulse_ towards the Parts, _&c._ from what this Liquor had before, that its very Nature will be changed, or in the common way of speaking, it will be truly and really _Fermented_. To understand aright how all this is done, it is necessary to hint somewhat concerning the Nature of _Fluids_ in General, and those Alterations in them which we call _Fermentations_; for I shall retain this known Word, tho’ in the proper Sense in which ’tis commonly used, there can be no _Fermenting_ of the Liquors in the Animal Body. And here I must refer to the Treatise of _Bellini de Fermentis_, who has with great Clearness shewn, that there is in all _Fluids_ not only a simple _Contact_ of their Parts, but also a _nisus in Contactum_, or _Cohæsion_, and this of a certain _Degree_ or _Force_, and besides, of a particular _Direction_; which is indeed, tho’ express’d in other words, the very same thing with the _Attraction_ of the Particles one to another; This Mr. _Newton_ has demonstrated to be the great Principle of Action in the Universe, has taught us the Laws of it in the greater Quantities and Collections of _Matter_; and he who rightly Studies his Philosophy will understand that the same obtains in the most Minute and Finest Corpuscles, which do unite into Bodies of different _Solidity_ and _Make_, according to the Degree with which they do mutually _attract_ each other, and to the _Superficies_, by which, when drawn, they do _touch_ and _adhere_. To this if we add a _Pression_ of the several Parts of the Fluid every way, and consider withal, that this _Uniform_ Attraction of the Parts to one another must be variously changed by the different Attraction of Heterogeneous Bodies mixt with them, we have the great Principles of all Fluids, upon which their several _Phænomena_ do depend.
