What Purposes does this Conceit serve? Why, only to support another Conceit, _viz._ That animal Substances most vigorously attract animal Effluvia, or that animal Effluvia run furiously into the Embraces of animal Substances; which we see by his fine Experiments, is a mere Fancy. As for _Musk_, _Cotton_ secures it the fastest from running away; nor do we find that _Feathers_, _Silk_ or _Wool_, are ever put upon that Service. But supposing every Thing true, and nothing whimsical, that has been now advanced by the Doctor, we might have expected a further Discovery; how these Perfumes come to desire their being beded, cherished, or fomented in soft animal Substances: Is it in Abhorrence of Annihilation, or by the Love they bear to one another? Or are they kept together, as the celebrated _Jonathan Wild_ keeps a Felon? In short, is it by _Sympathy_ or _Antipathy_? For if we are rightly instructed in these Matters, _these Remarks alone may lead us into_ great and useful Practices; for if they are skilfully employ’d, they may, perhaps, as I conjecture, keep the Plague at bay, by being strung up, like Pirates, at High Water Mark. For as dull as these Conceits may appear to be; such as never dropp’d before from any Man in his Senses; yet our Author, who has hitherto shewn himself Blind in every kind of Argument, is now become so Sharp-sighted of a sudden, when you are to take his Word for it, that he boldly asserts, That this _Remark alone_ (of Sympathy and Antipathy) _may serve to lead us a little into the true Nature of Contagion_. What! this Nature of Contagion, that is still unknown, after all Dr. _Mead_’s Endeavours; nay, _Sweats_ and _Labours_, to be drawn at length from Trifles that bear no Relation to Contagion.
