[59] Occasionally the lateral or accessory incisor may be developed or suppressed on one side only, a fact explaining the occasional occurrence of cases with three or five incisors present.

[72] Trendelenburg objects to the harelip operation being called a life-saving one, on the ground that the inability to gain sufficient nutriment depends rather on the associated cleft palate than on the cleft lip. But if the lip be united efficiently the method of feeding by bottle suggested at p. 66 enables the child to suck and swallow satisfactorily in spite of the palatal defect.

[75] In view of the dilatation of the nasal aperture, which often takes place at a later date, it is advisable to make it at first actually smaller than on the opposite side. [76] The lower lip may also be kept drawn down and everted by the use of collodion applied longitudinally between it and the chin, thus obviating in part the need of the constant application of the nurse’s finger. This ingenious plan has been suggested and practised by one of the sisters in my wards at King’s College Hospital.
