A doctor informs his patient's mother-in-law that he may need to resort to tapping - she misunderstands him as meaning tapping alcohol. Wood engraving by C. Keene, 1880.

Caption reads: 'Doctor (who has just seen the patient). "He's no worse, but" (gravely) "the question will, no doubt arise as to the advisability of tapping him!" Mother-in-law. "Oh, doctor, don't say that! Nothing was ever tapped in this house that lasted over a week!!"
