, The orifice of the fourth stomach.

, The longitudinal plicae of the fourth stomach.

, The rugous structure of the lower part of the fourth stomach.

Plate XIX.

This plate is intended to show the directions of the muscular fibres which run upon the orifices and sides of the cells in the first and second stomachs of the camel.

It represents six of the cells in the lower part of the left side of the first stomach, with a portion of the longitudinal ridge by which they are bounded. These particular cells were chosen in preference to those of the second stomach, as they were the largest, and the muscular fibres were most distinctly seen; the same structure is met with in the cells of the second stomach.

, The longitudinal ridge, to show its muscular structure, and the mode in which the fibres go off to furnish the orifices of the cells.

, The course of the fibres going from cell to cell to close their orifices.

, The muscular fibres by which the cells are enabled to throw out their contents.
