PROBOSCIS, n.
The rudimentary organ of an elephant which serves him in place of the knife-and-fork that Evolution has as yet denied him. For purposes of humor it is popularly called a trunk.
Asked how he knew that an elephant was going on a journey, the illustrious Jo. Miller cast a reproachful look upon his tormentor, and answered, absently: "When it is ajar," and threw himself from a high promontory into the sea. Thus perished in his pride the most famous humorist of antiquity, leaving to mankind a heritage of woe! No successor worthy of the title has appeared, though Mr. Edward Bok, of _The Ladies' Home Journal_, is much respected for the purity and sweetness of his personal character.
