No glands are found in the oviduct; the structureswhich have been described as such are, in all probabil-ity, folds of mucous membrane. It is not quite clear how the ovum is brought into theoviduct. The old theory that the fimbriated extremitygrasps the ovary at the time of extrusion of the ovum,and so receives it into the open endof the tube, has no facts to supportit, besides raising the difficulty ofaccounting for the wonderful direct-ing power which is to place the tubeon the right spot of the ovary at the.
