607 urethral smears were obtained from 330 women at the end of pregnancy. The cells of the stratified columnar epithelium were observed only in smears with at-term or post-term patterns : the presence of separated columnar cells is not significant ; in contrast small clusters of basal columnar cells or separated parabasal squamous cells characterize smears with post-term patterns. The significance of these observations is discussed.
