The former Piece of Knowledge is open to those only who are the familiar Friends of _Attractions_ and _Combinations_ made by Volatile Spirits; and we who are Strangers to these powerful Words, cannot hope for any Instruction. But to shew Dr. _Mead_ I have been at true Pains to come acquainted with them, I find there was Old Attraction, Son of _Aristotle_; and there is Young Attraction, the great Geometrician; and a Counterfeit of this in the Works of the celebrated Doctor _Anodyne Necklace_; which last is mighty like Attraction before us; but as he is spurious, I must own that I do not find how this Attraction brings me to a clearer Understanding of the foregoing Paragraph. As to Combination, whether that of Cooks, or Algebraists, it is of very little or no Use to me. I must confess, a good Use may be made of these Words; for they will exchange with _Fermentation_, at any Time that an Author finds himself disposed to write on a Subject without understanding it. For Instance, I now intend to make a short Discourse about the _Philosopher’s Stone_, and a Method for finding it; a very agreeable Offer to the Publick, when Money is scarce, and Credit very low, through the great Industry of the ingenious Directors of the _South Sea_. When, I say, a Man forms to himself this useful Project, _Attraction_ and _Combination_ does it at once. The Receipt is easy; it is but taking of _Attraction_, _Circulation_, _Cohobation_, _Concentration_, _a. q. s. Combination_, _q. s. M._ If this Receipt is duly managed, it will not only make the _Philosopher’s Stone_, and the grand _Elixir_, but cures the Plague, and all Diseases, _Curable_ or _Incurable_. But it is to be noted, that when you would explain how Attraction makes a Plague, you must be sure due Consideration be had to the Facility and Aptness of _all kind of Effluvia to be diffused in a warm Air, such as we have described an infectious one to be_. And, therefore, as the Whole of Infecting Air is an ill-made Story, supported by Cant and Gibberish, we will take Leave of it, and his mortify’d Limb together, tho’ it is brought to give further Light to this strange Stuff.
