TheFallopian tubes do not really exist save in the higher order ofanimals who have assumed the upright position. If we accept thisview the physiology of the process of reproduction is immenselysimplified and the pathology of ectopic gestation becomesintelligible. I cannot see that any other views than these areconsistent with. the recent discovery of Arthur Johnstone andBland Sutton, nor indeed can any others be reconciled with thefacts of ectopic gestation as unravelled by modern Fig. 1.—Section of normal Fallopian tube (after Bland Sutton). We have now to deal with the varieties of ectopic gestationI propose at once to dismiss all previous classifications occurred in my and I propose at once to dismiss all previous ciassiiications asinconsistent with the facts as they have occurred in my ownexperience and incompatible alike with the view of the explanationof the cause of ectopic gestation wliich I have offered and with thephysiology of impregnation. The uterus being regarded as the 6 TWO KINDS OF TUBAL PEEGNANCY. only site possible for normal pregnancy and the tract throughwhich the ovum passes and in which it may be impregnated in theabnormal process, it follows as a matter of course that all ectopicgestations must, in their origin, be tubal. A possible exception tothis may be the impregnation of an ovum in its vesicle before itleaves the ovary—a matter I shall discuss immediately. A clinical distinc
