    made to transfix the coronary artery, care being taken that the pin does not penetrate the mucous membrane, and double n a fold of it between the pared edges ; teing satisfied that the first pin brings the margin of the prolabium accurately into line, the upper one is passed in the same way and a silk suture twisted round each. The ends of the pins are thencu^ oft with pliers, and a small pad of gauze placed under each to prevent injury to the cheek ; several horse-hair sutures are then inserted to complete the apposition. The parts are then dried and covered with collodion, and a piece of strapping applied from cheek to cheek to support the lip and prevent traction when the child cries. In cases in which the cleft is not very wide or deep, silk-worm gut sutures may be used instead of hare-lip pins ; when the latter are used they should be removed after twenty-four to thirty six hours; if left longer they will produce scars. The twisted silk suture is not dis- turbed by removing the pins, and should be left adhering to the lip until firm union has taken place. When the fissure does not extend through the whole lip Nelaton’s operation may be performed. This consists in making an inverted V-shaped incision with its angle just above the apex of the cleft, each arm stopping short of the prolahium. The tissues below the incision are then drawn down, leaving a diamond-shaped wound ; on bringing the raw surfaces together by passing a suture or hare-lip pin horizon- tally, a projection on the border of the lip will be produced in place of the original cleft ; this disappears in time leaving the margin straight. Operation for double Hare-lip.—This is conducted on the same principle as that for single hat e-lip. When the premax- illary process projects, it should not be removed unless it is
