Note (return) — ORGANIC DIFFERENCES IN THE SEXES

An excess of all other anatomical anomalies, except cleft palate, is reported among males. Manley reports that of 33 cases of harelip treated by him only 6 were females.51 It appears also that supernumerary digits are more frequent in males. Wilder52 has recorded 152 cases of individuals with supernumerary digits, of whom 86 were males, 39 females, and 27 of unknown sex. A similar relation, according to Bruce, exists in regard to supernumerary nipples.53
