The frontal sinuses of 143 Eskimo skulls from two sites in the Hudson Bay region of Canada were examined radiographically. No between-site or sex differences were noted in the size of the sinuses. On average, the sinuses are small and often bilaterally absent. The Canadian samples have smaller sinuses than reported for Alaskan Eskimos or American Indian groups.

Temporal changes in average stature are often used as a measure of a past population's adaptation, or lack of it. Traditionally, stature estimates have been calculated using formulae derived from limb proportions of cadavers. However, many authors have noted the problem of regional or population variation in body proportions of such reconstructed ratios. Before differences in stature can be attributed to environmental adaptation, 'ethnic' or population differences in limb ratios must be taken into account. The present paper calculates the stature of a medieval Norwegian skeletal sample using archaeological plan femur length and dry bone femur length. The author presents a variety of formulae and compares the stature derived from these calculations to the stature derived from archaeological plans. The Trondheim statures are then compared to stature reconstructions of other contemporary populations.
