In considering a large number of cases the question at once arises, what method of classification is to be followed, and how are the particular cases reported in full to be selected? A mere chronological history of the cases would be wearisome and uninteresting. It is perhaps natural that the early lecture room method of considering the subject should suggest itself as the most suitable for the purpose in view. I therefore propose to group my cases under: I. Normal Labours: 1. Unaided 2. Membranes artificially ruptured. 3. Forceps. 4. Grave complications in Puerperium, Puerperal Insanity. II . Praeternatural Labours : 1. Pelvic. 2. Transverse. III. Complex Labours.: 1. Placenta Praevia . 2. Retained Placenta. 3. Eclampsia. IV. Foetal Complications: 1. Prolapse of Cord. 2. Twins. 3. Anerz. cephalus.
