Tubal peristalsis in women, in spite of abundant opportunity for observation, has so far not been observed or described as occurring during laparotomy. This physiologic function of the fallopian tubes has been assumed by embryologists and physiologists to be a necessary factor in the transportation of the ovum. Recent work on animals and on the extirpated and surviving uterus and tubes has actually established the phenomenon of tubal peristalsis. The experiments of Keye,1of Corner and his associates2Seckinger3and Snyder,4and of Sun,5Lee6and Hartman7of the Carnegie Embryological Institute of Washington, D. C., have demonstrated rhythmic contractions of the oviducts in the commonly employed experimental animals. Corner has shown the same to be true of the extirpated but surviving tubes of monkeys and of the human species. The results were corroborated more recently by Rudolph Kok,8von Mikulicz-Radecki9
