It might occur to one on first thought that, in respect to treatment, the cases of placenta prævia could profitably be divided into two great classes—the complete and the incomplete. The mortality statistics bear out this thought in a measure, for in a series of 1,300 cases the mortality in the complete variety was 13.4 per cent., while in the incomplete variety it was but 4.3 per cent. In actual practice, however, such a general division is not practicable. In most cases the exact relation that the placenta will bear to the dilated cervix can be determined only after the cervix is well dilated in the process of delivery. The nice grouping of cases that we see in statistics is made after treatment, not before. Of course, there are certain cases which, from the examination, can be definitely set down as placenta prævia centralis or placenta prævia lateralis, but these
