3£>4 Mr . Home’s Observations on the Camel’s Stomach 
which terminate in it, so as to oppose the end of the oesopha- 
gus, and receive the morsel, without the smallest risk of its 
dropping into the second stomach. 
The third stomach of the bullock is a cavity, in the form of 
a crescent, containing 24 septa, 7 inches broad, about 23, 4 
inches broad, and about 48 of 1^ inch, at their broadest part. 
These are ranged in the following order. One broad one, 
with one of the narrowest next it ; then a narrow one, with 
one of the narrowest next it ; then a broad one, and so on. 
The septa are very thin membranes, covered with a cuticle, 
and have their origin in the orifice leading from the oeso- 
phagus, so that whatever passes into the cavity must fall 
between these septa, and describe three-fourths of a circle, 
before it can arrive at the orifice leading to the true stomach, 
which is so near the other, that the distance between them 
does not exceed three inches : and therefore the direct line 
from the termination of the oesophagus to the orifice of the 
fourth stomach is only of that length. While the young calf is 
fed on milk, that liquor, which does not require to be rumi- 
nated, is conveyed directly to the fourth stomach, not passing 
between the plicae of the third ; and afterwards the solid food 
is directed into that cavity, by the pJicae being separated from 
each other. 
The food found in the third stomach is of the consistence 
of thick paste: and is met with in the form of flattened 
pellets, distributed between the different septa. 
When this cavity is opened, it emits an odour of a very 
unpleasant kind, arising from the process, which the food 
undergoes in it. 
The third stomach opens into the fourth by a projecting
