ibo Mr. Home on the Structure of the Stomachs 
to be made up of an infinite number of small white tubes, the 
direction of which is perpendicular to the internal membrane. 
The cavity of the stomach is divided into two portions ; the 
cardiac is the largest, forms the general cavity, and when in 
a contracted state, has a rugous internal surface : the pyloric 
is small, and projects from one side of the other. Immediately 
beyond the pylorus the duct of the liver opens. Vide Plate 
XII. fig. 2 and 3. 
XXI. The Cormorant. 
The stomach is formed on the same general principle as 
that of the hawk ; but the solvent glands differ so much in 
their appearance from those of other birds of prey, that I have 
represented them in the annexed drawing. The cuticular 
lining of the oesophagus terminates at the orifice of the sto- 
mach, and several openings of the oesophageal glands are seen 
at that part. Immediately within the stomach are situated 
the solvent glands, forming two circular projecting surfaces, 
each of them i|- inch in diameter, covered with small orifices 
like pin holes, which extend into the substance of the gland. 
The communication with the pyloric portion is on one side 
just below these solvent glands. Vide Plate X. fig. 2 and 3.. 
XXII. The Viper . 
The stomach is a continuation of the oesophagus: its origin 
is distinguished by the termination of the cuticular lining of 
that canal, the coats becoming thicker at that part, and the 
inside being surrounded by a zone of solvent glands. The 
cardiac portion terminates in a small orifice at its lower part, 
and the pyloric is through its whole extent not wider than this 
orifice ; its internal membrane has longitudinal folds ; but
