The extent of congenital cleft may vary from the slightestmanifestation, that of a bifid uvula, to the grossest form of conjoined cleftpalate and hare-lip, in which the fissure involves not only the velum palati andhard palate, but penetrates one or both sides of the alveolar arch and upperlip. with the presence of a separate intermaxillary structure. This article,however, will not embrace the subject of hare-lip except incidentallv (Figs. 15,16. 17;. Fig. i; Pro. 15 Fig. Bitid Uvula. Cleft Palate Cleft Palate and Hare-lip con-joined. Etiology and Pathology.—Nature fails to complete her design as origin-ally intended, and the defect doubtless dates from an early period of intra-uterinelife. It is assumed that the same causes which produce rickets in children areprone to effect cleft palate. A deficient supply of phosphates in the diet of themother, or failure on her part to thoroughly assimilate the phosphatic elements,may be regarded as an exciting cause. Vander Veer states that several years ago the lions in the Zoological Gar-dens of London were fed upon flesh containing too large bones for them tobreak and swallow, as is their custom. The young born while this method offeeding was pursued were observed to have cleft palates, and lived but ashort time.
