Observations on the lower ends of 378 femora from modern Japanese who were accustomed to squat both at rest and at work were made and compared with other published results.<BR>The average mean of the so-called squatting number by which the depth of the intercondylar fossa at the level of the intercondylar line was to be multiplied to give the greatest depth of the lower articular surface of the femur for Japanese was 3.23.It gave Japanese an intermediate position between Punjabis (2.90) or Indians (3.10) and modern Canadians (3.43) or Irish (3.44).It was, however, found that the Japanese femora were not distin-guishable from the modern Irish or Canadian ones by the so-called squatting number, because there was a considerable amount of overlap of the squatting number among them.<BR>The depth of the intercondylar fossa in female was relatively greater than that in male, the difference being attributed to the fact that the articular surface of the knee joint in female was absolutely smaller than that in male.It was, therefore, necessary in comparison of the so-called squatting numbers of the femora among different populations to consider first whether given bones were of male or of female.<BR>In addition, the average mean of the squatting index of SHAH for Japanese was 31.0 (male 30.3, female 32.5), being smaller than that (34.2) for Punjabis.
