_Floor of auditory meatus._—Among the Indians, and particularly in the young, there are frequently found more or less pronounced defects or dehiscences (Hyrtl) in the floor of the auditory meatus. The frequency of these defects differs from locality to locality and probably from tribe to tribe. They are rather scarce in the Munsee, two-thirds of the crania showing no defect whatever, while of the remainder in only one instance was the perforation large. There seems to be a predominance of this condition in the females.
