This becomes obvious in the lesser degrees of deformity represented in JigsA62. and 463. In fg. 462., although the commissure is placed at a higher point than mfig. 461., so as to be much further removed from the external os, there is still a considerable separation of the two cornua, and their direction is still mainly horizontal ; but in Jig. 463., where a more per- fect coalescence of the two halves has taken Fig. to the extremity of the vagina, dividing the latter, fg. 461., together with the hymen in the virgin state, so that there are two com- plete canals leading to corresponding uterine halves. Group IV. In this group the external form of the uterus differs but little from the normal character. The breadth of the organ, especially between the points of entrance of the Fallopian tubes, is usually greater, and the fundus, though arched, is more shallow than usual. Here also a slight notch, extending into a shallow furrow, running along the posterior uterine wall, may indicate the seat of that in- ternal vertical septum which more or less completely divides the uterine cavity into two halves, and constitutes the uterus bilociilaris (fig. 464.). Fig. 464. The comua mote completely united externally, find the two halves becoming more nearly parallel. (Ad Nat.) The body is still divided by an internal septum •which descends from the commissure as far as the commencement of the cervix, where it ends in a thin falciform edge. place, and, consequently, where the com- missure approaches nearer to the points of attachment of the Fallopian tubes and round ligaments, the angle has become
