The science and art of surgery : being a treatise on surgical injuries, diseases, and operations . ial nodule is commonly attached. Inmany cases this is pushed forwards, and tilted onits base, so that tiie alveolar border projects forwards. Sometimes theprojection is so considerable that it is attached to the tip of the nose. Median fissure is so rare that there are scarcely any authenticcases of it in the records of surgery. Delahaye,however, mentions one instance of mesial fissureof the upper lip with two lateral fissures, andNicati has described one in the lower lip, theonly case of the kind that I have met with onrecord. The cleft in hare-lip corresponds to the line ofjunction between the embryonic intermaxillarybones and the superior maxilla. The fissure,wlien single, nja_y be confined to the lip; butin the majority of cases it extends to the alve-olus of the upper jaw, giving rise to a deepnotch between tlie outer incisor and the canine ^=- of jaw .,, f-fr, •,•111 ,1 ^ • • in Double Hare-lip, and Cleft tooth.

Meckel and Nicati have described a rareform of hare-lip, in which the fissure corresponds to the line of junctionbetween the central and lateral incisors. In many cases tlie fissureextends back into the palate ; tiiis more frequently happens when theliare-lip is double, and in these eases every variety of palatal deformityis met with (Fig. 604). Age for Operation—The cure of hare-lip can only be effected by apropeily conducted operation. In the performance of this, the first pointthat lias to be determined is the age at which it should be done. Onthis there has been, and is still, a good deal of difference of generally are, however, I think, agreed that it is better not toperform the operation during dentition ; at all events
