The cause of thisoverdevelopment will usuallybe found in a preexisting endo-metritis, which predisposes themembrane to respond with inor-dinate vigor to the stimuluswhich an impregnated ovulealways furnishes the uterine mu-cosa to rapid growth and devel-opment. It may be possible,however, that the death of theembryo or some disease of theovum may prove irritatingenough to incite the mucousmembrane of the uterus, previ-.
