Another way of their attraction is also delivered; that is, by a tenuous emanation or continued effluvium, which after some distance retracteth into it self; as is observable in drops of Syrups, Oyl, and seminal Viscosities, which spun at length, retire into their former dimensions. Now these effluviums advancing from the body of the Electrick, in their return do carry back the bodies whereon they have laid hold within the Sphere or Circle of their continuities; and these they do not onely attract, but with their viscous arms hold fast a good while after. And if any shall wonder why these effluviums issuing forth impel and protrude not the straw before they can bring it back, it is because the effluvium passing out in a smaller thred and more enlengthened filament, it stirreth not the bodies interposed, but returning unto its original, falls into a closer substance, and carrieth them back unto it self. And this way of attraction is best received, embraced by Sir _Kenelm Digby_ in his excellent Treaty of bodies, allowed by _Des Cartes_ in his principles of Philosophy, as far and concerneth fat and resinous bodies, and with exception of Glass, whose attraction he also deriveth from the recess of its effluction. And this in some manner the words of _Gilbertus_ will bear: _Effluvia illa tenuiora concipiunt & amplectuntur corpora, quibus uniuntur, & electris tanquam extensis brachiis, & ad fontem propinquitate invalescentibus effluviis, deducuntur_. And if the ground were true, that the Earth were an Electrick body, and the air but the effluvium thereof, we might have more reason to believe that from this attraction, and by this effluction, bodies tended to the Earth, and could not remain above it. Our other discourse of Electricks concerneth a general opinion touching _Jet_ and _Amber_, that they attract all light bodies, except _Ocymum_ or _Basil_, and such as be dipped in oyl or oyled; and this is urged as high as _Theophrastus_: but _Scaliger_ acquitteth him; And had this been his assertion, _Pliny_ would probably have taken it up, who herein stands out, and delivereth no more but what is vulgarly known. But _Plutarch_ speaks positively in his _Symposiacks_, that _Amber_ attracteth all bodies, excepting Basil and oyled substances. With _Plutarch_ consent many Authors both Ancient and Modern; but the most inexcusable are _Lemnius_ and _Rueus_, whereof the one delivering the nature of Minerals mentioned in Scripture, the infallible fountain of Truth, confirmeth their vertues with erroneous traditions; the other undertaking the occult and hidden Miracles of Nature, accepteth this for one; and endeavoureth to alledge a reason of that which is more then occult, that is, not existent.
