_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.
