finally turns down in a gradual curve, without any recognizable 

 line of demarcation between it and the uterus. 



If he follows the floor of the vagina and palpates carefully as 

 his hand passes along, he will discover to his astonishment a 

 hard body lying beneath it, which upon careful manipulation 

 he may recognize as portions of the fetus, lying directly against 

 the vaginal floot, and impressing him very strongly at first with 

 the idea of extra-uterine pregnancy. If he will follow the 

 uterine floor further, to the extent of nearly the entire length of 

 his arm, his hand suddenly passes downward into the uterine 

 cavity, and he finds that the floor which he has been following 

 bends abruptly backward to constitute the roof of the uterus, 

 immediately beneath which the fetus lies transversely with its 

 ■dorsal surface presenting toward the pelvic inlet.
