Describes (p. 678) “McBurney’s point”: “The seat of greatest pain, determined by the pressure of one finger, has been very exactly between an inch and a half and two inches from the anterior spinous process of the ilium on a straight line drawn from that process to the umbilicus”. McBurney also includes a description of some successful cases of early operation for perforative appendicitis. Reprinted in Med. Classics, 1938, 2, 506-31.
