Sir P monologue — Volpone

Beside my water-works: for this I do, sir. First, I bring in your ship 'twixt two brick walls; But those the state shall venture: On the one I strain me a fair tarpauling, and in that I stick my onions, cut in halves: the other Is full of loop-holes, out at which I thrust The noses of my bellows; and those bellows I keep, with water-works, in perpetual motion, Which is the easiest matter of a hundred. Now, sir, your onion, which doth naturally Attract the infection, and your bellows blowing The air upon him, will show, instantly, By his changed colour, if there be contagion; Or else remain as fair as at the first. --Now it is known, 'tis nothing.
