Studies were conducted to quantify histological age changes in the human bone cortex. Ground cross sections of the femur were measured for : (1) the number of osteon per mm^2,(2) the number of interstitial lamellae per mm^2,(3) average size of osteon and (4) the average diameter of the Haversian canal. These data were obtaind from 45 subjects of Japanese males ranging in age from 41 to 102 years. Significant correlations (significant level at 1%) were recognized between the actual age and three values ((1)〜(3)). The correlation between the actual age and diameter of canal was not significant. Regression equations for estimating the actual age were calculated with 40 samples selected by using 14 provisional regression equations calculated with original samples. 73.4% of the estimates were within ±10 years of the actual ages of the original 45 subjects.
