"Give Up The Ghost"
Context: Having safely completed the adventure of the Helmet of Mambrino, a barber's basin Don Quixote mistakes for the headpiece of a famous warrior, he and his squire ride along discussing the Knight's magic cure, spilled when a shepherd with his slingshot broke the jar containing it. Sancho says he would rather die then use it:
". . . I lost my precious balsam indeed; but I do not much repine at it, for thou knowest I have the receipt in my memory." "So have I, too," quoth Sancho, "and shall have while I have breath to draw; but if ever I make any of that stuff, or taste it again, may I give up the ghost with it!"
