[To Doctor.] Doctor, the thanes fly from me.[To SEYTON.] Come, sir, dispatch. [To Doctor.] If thou couldst, doctor, castThe water of my land, find her disease,And purge it to a sound of pristine health,I would applaud thee to the very echo,That should applaud again.—[To SEYTON.] Pull’t off, I say.—[To Doctor.] What rhubarb, cyme, or what purgative drug,Would scour these English hence? Hear’st thou of them?Doctor. Ay, my good lord; your royal preparationMakes us hear something.Macbeth. [To SEYTON.] Bring it after me.I will not be afraid of death and bane,Till Birnam forest come to Dunsinane.[DOCTOR looks perplexed by Macbeth’s request and stealthily sidles away.]Doctor.
