respecting the JVater it contains , &c= 367 
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 stomach in the 
camel performs the same office as the second in the ruminants 
with horns. While the camel is drinking, the action of the 
muscular band opens the orifice of the second stomach, 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 struc- 
ture of the first stomach 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 un- 
usual number of days without water, acquire the power of 
dilating the cells, so as to make them contain a more than 
ordinary quantity as a supply for their journey, at least such 
is the account given by those who have been in Egypt. 
When the cud has been chewed it has to pass along the 
upper part of the second stomach before it can reach the 
third. How this is effected without its falling into the cellular 
portion, could not from any inspection of dried specimens 
be ascertained ; and it was in this state only that Mr. Hunter 
saw the internal structure of the camel’s stomach ; but when 
the recent stomach is accurately examined, the mode in which 
this is managed becomes very obvious. At the time that the 
cud is to pass from the mouth the muscular band contracts 
with so much force, that it not only opens the orifice of the 
second stomach, but acting on the mouth of the third, brings 
it forwards into the second, by which means the muscular 
ridges that separate the rows of cells are brought close toge- 
ther, so as to exclude these cavities from the canal through 
>vhich the cud passes.
