Transcript3494: A portion of one of the horns of a pregnant uterus of a Ewe, from which the foetus and its membranes and cotyledons have been removed. Several of the cotyledons of different sizes are shown. These are hemispherical in shape, with a central cavity bordered by a sharp margin beset by delicate villous processes. One cotyledon is in section; it is completely hollowed out by a spacious cavity which, in the natural state, was filled by the foetal cotyledon, and is lined by a soft honey-combed membrane.
