Is not this, I say, as reasonable, as that the Matter taken from one that lyes ill of the gentlest and most kindly Small-Pox, should propagate only that Sort, and not the dangerous? If this Arguing be not close and conclusive, let the Weakness of it, and the Disparity of Reason, be made appear: But if it be just and valid, then if the Inoculators are by their Operation highly useful and beneficial to the World, as their Promoters affirm, then, I say, I have refined upon that Invention, and have started a Practice of greater Importance, and far more extensive Benefit to Mankind, and shall leave it to them to make their Advantage of it.
