The coexistence of different types is common, such forinstance as the combination of syndactylism with anomaliesand deficiencies of the phalanges, which is the type illus-trated by the first group of cases to be presented in this. FIGURE 6. paper. The coexistence of anomalies and deficiencies ofother parts of the body with deformities of the phalanges iscommon. Harelip and cleft palate are not infrequent inpatients with deformed phalanges. In Case III., herereported, the coexistence of syndactylism with deformity of ANOMALIES OF THE PHALANGES. 9 the phalanges, and syndactylism with supernumerary toes inthe same patient is noted. Plereditary transmission is com-mon, and a tendency to the reversion to the same or analagousdeformities in families is exemplified in the two familieswhich form the basis of this paper. The causes are obscure, and in cases such as those herereported, can only be assigned to deep-seated innate tenden-cies to aberrant development, often definite and fixed, and
