The frequencies for each trait in each population sample is presented in Table 2, while the sample size for each population and each trait is presented in Table 3. Table 4. presents the mini­mum and maximum frequency and the range in frequen­cy for each trait in this study. Side Asymmetry Chi square values (see FINNEGAN, 1972) for each of the bilateral traits over the seven samples, tested left to right differences in the male sample. Eighteen of these values were significant at the .05 level or better, which exceeds the 12 significant differences expected due to chance alone. However, in 8 of the 18 cases the sample size (N) was less than 10 on one or both sides, and we expect that the sample size is one of the primary causes for these significant differences. Aside from this, 4 traits, Asterionic Bone, Accessory Infraorbital Foramen, Mandibular Foramen Double, and Posterior Ethmoid Foramen Absent showed a significant difference in more than one sample. In no case did a trait display significant side asymmetry in more than two samples. The remaining significant differences are scattered among the samples and among the traits tested. When compared to other samples tested for side asymmetry, we suggest that the present samples show a random distribution of these significant differences. In the female sample, 12 significant differences were generated at the .05 level or better. Chance expectation is 12.25 at the .05 level, so the generation of 12 signi­ficant differences is less than chance expectation. How­ever, at the .01 level of significance we would expect less than three significant differences were actually found. While this exceeds chance expectation at the 0.01 level, three these are most probably due to small sample size (N=12 or less on one or both sides in a particular sample) which would bring the number of side asym­metry significant differences under chance expectation. As in the male sample, left to right side significant differences in females were randomly distributed with no trait showing a significant side asymmetry in more than one sample. It should here be pointed out that a number of researchers (SUCHEY, 1975; GREEN, SUCHEY and GOKHALE, 1979) have suggested using only one side in the analysis of population differences. However, in this set of samples, as we have seen in numerous other sets of samples, while few side to side differences are signi­ficant, they are often numerically much larger than zero. Indeed, this difference in itself has been used by FlN­NEGAN and RUBISON (1980, 1984) and FINNEGAN and MCGUIRE (1979) in assigning one cranium (or infracra­nial skeleton) to its logical parental population. It is for these reasons that we beleivé the traits for both sides, in the case of bilateral traits, should be pooled in the final analysis.
