"This cellular structure is in the left compartment of the first cavity ; and there is another of a 



more superficial kind on the right, placed in exactly the. opposite direction, made up of twenty-one 



rows of smaller cells, but 



entirely unconnected 



with the great ridge. 

 " On the left side 



of the termination of 



the oesophagus, a broad 



muscular band has its 



origin from the coats of 



the first cavity, and 



passes down in the 



form of a fold, parallel 



to the great ridge, till 



it enters the orifice of 



the second, where it 



takes another direction. 



It is continued along 



the upper edge of the 



cavity, and terminates 



within the orifice of a 



small bag, 'which may lie 



termed the thud cavity. 

 " This band on one 



side, and the great 



ridge on the other, form 



a canal, which leads 



from the cesophagus down to the cellular structure in the lower part of the first cavity. 



" The orifice of the second cavity, when this muscle is not in action, is nearly shut : it is at right 



angles to the side of the first. The second cavity forms a pendulous bag, in which there are twelve 



rows of (-ells, formed by as many strong muscular bands, passing in a transverse direction, and 



intersected by weaker muscular bands, so as to form the orifices of the cells. Above these cells, 



between them and the muscle which passes along the upper part of the cavity, is a smooth surface, 



extending from the orifice of this cavity to the termination in the third. 



" From this account, it is evident that the second cavity neither receives the solid food in the tir.it 



instance, as in the bullock, nor does the food afterwards pass into the cavity, or cellular structure. 



" The food first passes into the first compartment of the first 

 cavity, and that portion of it which lies in the recess, immediately 

 below the entrance of the cesophagus, under which the cells are 

 situated, is kept moist, and is readily returned ints the mouth, 

 along the groove formed for that purpose, by the' action of the 

 strong muscle which surrounds this part of the stomach, so that 

 the cellular portion of the first cavity in the camel performs the 

 same office as the second in the ruminants with horns. 



"While the camel is drinking, the action of tin; muscular 

 band opens the orifice of the second cavity, at the same time that 

 it directs the "water into it ; and, when the cells of that cavity 

 are full, the rest runs off into the cellular structure of the 

 first cavity, immediately below, and afterwards into the general 



cavity. It would appear that camels, when accustomed to go journeys, in which they are 



kept for an unusual number of days without water, acquire the power of dilating the cells, so as to
