178 3 Mr. Home on the Structure oj the Stomachs 
Fig. 4. Represents the hare's stomach inverted, to show its 
natural form, and the appearance of the different parts of its 
internal membrane. 
a. The oesophagus. 
b b. The cardiac portion. 
c . A muscular band separating the cardiac from the pyloric 
portion. 
d d. The pyloric portion. 
e. A glandular appearance believed to be the solvent glands. 
f. The pylorus. 
g. The duodenum. 
Fig. 5. Is an external view of the rabbit's stomach distended 
with air, to show the muscular coat ; the fibres are uniformly 
of the same strength over the whole of the cardiac portion, but 
where the pyloric portion begins they are stronger, and con- 
tinue so half way to the pylorus, at which part there is a circular 
band, and beyond it the fibres become spiral to the pylorus ; 
the layers of spiral fibres decussate one another.

Fig. 1. Is a view of the beaver's stomach inverted, to 
show its shape and the appearance of the internal membrane. 
a. The oesophagus. 
bb. The cardiac portion. 
c. The glandular structure peculiar to this stomach, which 
appears to be a cluster of solvent glands. 
d. The contraction between the cardiac and pyloric portion. 
e. The pyloric portion. 
f. A glandular zone at the pylorus. 
g. The duodenum.
