Here, often one to several inches from the vaginal extremity of the cervical canal, the pavement epithelium of the vagina ends and the cervical epithelium with its intricate and ela- borate mucous glands succeeds. The secretions of the two areas are wholly unlike. The protruding cervical mucosa, like that remaining within the cervical canal, takes the leading part in the elaboration of the thin mucus of estrum and, in pregnancy, of the uterine Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Williams, Walter Long, 1856- [from old catalog]; Williams, Walter Wilkinson, 1892- [from old catalog] joint author.
