Two case histories are given of women with 'patterns of abortion', premature deliveries, or still births. Whatever may be the internal or external agents predisposing to abortion, it appears from these histories that some persons develop an abortion habit just as others develop an accident habit, and that this habit may be interrupted by well-directed psychosomatic treatment. The practical aspect and some theoretical possibilities of coöperation between obstetrician, pediatrician, and 'psychosomatic consultant' are discussed. It seems that such coöperation offers a virginal field for research and practice.
