Ineither case the ovum develops external to the lumen, in the wallof the tube, and the tissues of the tube-wall form for it a gestation-sac or capsule. In intra-uterine pregnancy the embedding is not deep ; penetrationnever extends beyond the mucous membrane into the muscle ; indeed,it does not reach very deeply into the mucosa, so that the growingembryo forms, almost from the first, a vesicular projection towardsthe uterine cavity. The more superficial the embedding in the tube,the more striking is the analogy of tubal pregnancy to uterine 10
