The leg bones of 54 juveniles from the Romano-British cemetery at Poundbury, Dorset, were examined radiographically for Harris lines. No correlation was found between presence/absence of Harris lines and femoral length, cortical index, or total cortical thickness, although all three were significantly correlated with dental age for both groups. These results are compared with those of previous studies and differences are interpreted in terms of the nature of the environmental stress which gave rise to the Harris line. In the light of these findings a strategy is suggested which might be adopted for future research in this area. -- AATA
