In operating on cases of tubal gestation, a mole is frequently foundamong the blood effused into the peritoneal cavity by rupture orabortion ; it exactly resembles a lump of blood-clot, and may remainunnoticed unless carefully looked for. Small moles are nearlyglobular {see Fig. Ill); larger ones are oval in shape, heavier, and firmerthan simple clotted blood {see Fig. 110) ; they often show remains ofthe amniotic sac on section, and on microscopic examination, after 204 GYNAECOLOGY suitable hardening, are found to contain chorionic villi imbedded
