    os uteri, and a lower opening communicating with the vagina, and termed the external os uteri. The mucous membrane lining this cavity is thrown into folds with a peculiar arrangement like the feathers of a quill pen, called the arbor vitse, to be described later. The cervix itself has been divided into two or even three sections by different observers, but the simplest method is the former, by which any portion felt projecting into the vagina is called the vaginal portion, or portio vaginalis (Fig. 4: 4), while all the organ between the reflection of the vaginal mucous mem- brane and the level of the internal os uteri is the portio suprco- vaginalis, or supra-vaginal portion (3). The former can be felt per vaginam projecting more or less into the vagina, and the Fig. 6. Fig. 7.

Orifices of Fallopian tubes. 5. Os uteri externum. external os uteri can be made out by the examining finger as a dimple. The cervix projects a varying amount into the vagina, the anterior lip appearing shorter than the posterior: it is almost flush with the vaginal roof in the infant, while after the menopause gradual atrophy takes place. The os uteri externum is a transverse slit about | inch in diameter in the nulliparous woman : it becomes broader after labour (i to f inch), and more patulous, with slight eversion of the cervical mucous membrane. Dimensions of the Uterus and Cervix as a whole.—The total length in the fully developed virgin by external measurement amounts to about 3 inches, the cavity being inches. The relation of the length of the true uterine to the cervical canal varies, but usually it is i£ inch and 1 ineh respectively. The
