ee, The rows of cells which form a reservoir for the water. 
f. The opening leading into the third stomach. 
g. The cavity of the third stomach.

ii y The longitudinal plicae of the fourth stomach. 
kk, The rugous structure of the lower part of the fourth 
stomach.

pylorus.

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 dis- 
tinctly seen ; the same structure is met with in the cells of 
the second stomach. 
aa, The longitudinal ridge, to show its muscular structure, 
and the mode in which the fibres go off to furnish the orifices 
of the cells. 
bbbbb, The course cf the fibres going from cell to cell to 
close their orifices. 
cc. The muscular fibres by which the cells are enabled to 
throw out their contents.
