He's proudly testimonialised; folly or purchased cunning
Crack up his nastiest nostrums, keep his worst deceptions running.
He will bleed you and blackmail you, if you're weak as well as wealthy,
Impoverish and drench you, aye, do aught—save leave you healthy.
For 'tis quack, quack, quack! and 'tis drum, drum, drum!
And Dulcamara—when not worse—is safe to prove a hum!
Quack! Quack! Quack! It is time that cry to quelch
By Law—or else to treat the quacks like sorry rogues who "welsh";
And if Dulcamara's really safe, until the Law they alter,
Why honest men must see to it, nor in their purpose falter
