The case was sub-mitted to operation, and as the patient recovered a detailed histo- 192 GYNECOLOGY logical examination of the uterus and Fallopian tubes was not there can be no inherent impossibility about the occurrenceof primary peritoneal pregnancy, its actual demonstration is besetwith great difficulties, and there can be no question that if it occurs.

OVARIAN PREGNANCY It is only within recent years that the occurrence of ovarianpregnancy has been satisfactorily proved, but the number of caseswhich can be accepted as reliable instances of the condition is nowfairly large. There can be no doubt that it is very much lessfrequent than tubal pregnancy. In most cases the site of implan-tation appears to have been a Graafian follicle, which may beentered by spermatozoa through the site of rupture, or possibly bydirect penetration of the wall. It is, however, possible that the egg-cell may be impregnated when lying upon the surface of the ovaiy afterits discharge from the follicle, and may afterwards excavate a bed EXTRA-UTERINE (ECTOPIC) GESTATION 193 for itself in the ovarian tissu
