portion I consider to belong to the stomach, and to form a part 
of the digestive organ. It terminates by a tolerably defined 
line, where the villous appearance of the duodenum begins.

No. II. The Cod Fish. 
The stomach of the cod is a direct continuation of the oeso- 
phagus, from which its origin is only to be distinguished by 
the termination of the cuticular lining. It is made up of two 
cavities ; one large, which I shall call the cardiac portion, the 
other small, which I shall call the pyloric. The cardiac cavity 
terminates in a rounded extremity ; and on one side, a little 
above its termination, it communicates with the pyloric by a 
very narrow opening. 
From the cuticular lining of the oesophagus project a num- 
ber of small processes, as in the turtle, but formed on an in- 
finitely smaller scale ; these, when examined, do not appear 
to be tubular, any more than those in the turtle. The internal 
membrane of the cardiac portion is thrown into longitudinal 
folds of an irregular form, and there is a secretion of viscid 
mucus from every part of its surface ; there are also numer- 
ous orifices distinctly seen on the prominent parts of these folds, 
which I consider to belong to the solvent glands. These are 
in greatest number towards the lowest extremity, but are 
met with towards the upper end. 
The pyloric cavity has an internal surface of a very different 
kind ; it resembles a fine honey-comb, or network. Vide
