The omentum or caul, by the way, is membrane. All sanguineous
animals are furnished with this organ; but in some animals the organ
is supplied with fat, and in others it is devoid of it. The omentum

vivipara, in the centre of the stomach, where the stomach has a kind
of suture; in non-ambidental vivipara it has its starting-point and
attachment in the chief of the ruminating stomachs.
