Dr. C---, a wealthy doctor of laws, was providing good cheer for the entertainment of a few choice friends on Christmas-day, and ordered of the butcher four ribs of the tempting-looking beef. The man, unwilling to cut up the animal until she had enjoyed her full share of admiration, wrote upon a piece of paper, in large characters, "Prize Heifer--four ribs for Dr. C---;" this he pinned upon the carcase of the beast. Shortly after the doctor quitted the market, and a very fat young lady and her mother came up to the stall to make some purchases. Our student was leaning carelessly against it, watching with bright eyes the busy scene; and being an uncommonly mischievous fellow, and very fond of practical jokes, a thought suddenly struck him of playing off one upon the stout young lady. Her back was towards him, and dexterously abstracting the aforementioned placard from the side of the heifer, he transferred it to the shawl of his unsuspecting victim, just where its ample folds comfortably encased her broad shoulders. After a while the ladies left the market, amidst the suppressed titters and outstretched fore-fingers of butchers and hucksters, and all the idle loafers the generally congregate in such places of public resort. All up the length of King street walked the innocent damsel, marvelling that the public attention appeared exclusively bestowed upon her. Still, as she passed along, bursts of laughter resounded on all sides, and the oft-repeated words, "Prize Heifer--four ribs for Dr. C---;" it was not until she reached her own dwelling that she became aware of the trick.
