Composite stomach of the Sheep. with villi ; these give to the membrane a pe- culiarly rough aspect, and at different portions of the cavity their form is curiously modified. Usually they are remarkably prominent, pe- dunculated, more or less club-shaped and compressed; or they may be tapering and pyriform. In some localities their size is insignificant, and they almost disappear at the margins of the salient folds. In the Gi- raffe we find their dimensions strikingly uni- form at one spot, while, in another region great irregularity in this respect is observable; the same remark holds good in other horned species, where the deviations from this type are too slight to merit a separate notice. The organisation of the paunch in the Camelidae differs very materially from that of the ordinary ruminant. Instead of presenting a rou»h internal surface, crowded with viliosities, the mucous membrane is conspicuously smooth and entirely destitute of villi ; but the most remarkable feature consists in the presence of numerous small pouches, specially fitted for the reception and retention of water (fig. 360.). These Fig. l>'.tier-cells in the pinnch of the Camel. sacs, which may be looked upon as so many diverticula developed from the walls of the cavity, are arranged in two distinct groups — one on the right side and the other on the left; the former being by far the larger, and in the adult Dromedary measuring about one foot and a half in length, and six inches in breadth (Meckel). The cells of each batch are disposed in parallel rows, separated from one another by strong muscular bundles, given off from a single large band of fibres which commences at the cardiac extremity of the rumen, and proceeds in a longitudinal direc- tion, dividing the entire cavity into two com- partments. The muscular fasictili are arranged transversely, and give off secondary bundles at tolerably regular interva
