middle and 1} at tip, and ; of an inch thick. It was smooth 
in its central portion, but somewhat rough at tip; the folds at 
its base were arranged in a circular contorted manner, and 
were very prominent. 
The hyoid bone sent upwards a rounded cartilaginous con- 
tinuation, made prominent at will in the mouth; the soft pal- 
ate hung down to meet this, by which the cavity of the 
mouth could be completely shut off from the fauces. The 
nostrils opened externally at the very tip of the nose, and 
internally behind this curtain, so that respiration can go on 
when the mouth is full of water, if the end of the nose be 
exposed to the air. 
From the base of the tongue to the cardiac orifice was two 
feet. The longitudinal fibres of the esophagus were very dis- 
tinct near the stomach, forming prominent rough folds. Just 
below the hyoid bone it measured, cut open, 6 inches in 
width; at the cardiac orifice 4} inches. 
The stomach was filled with half-digested food. It was 
nearly globular, measuring about 9 inches in all diameters. 
The walls were half an inch thick ; the inner surface smooth, 
of a dull white color, without evident papille. It was studded 
with what resembled erosions, or ulcerations, most numerous 
on the greater curvature, opposite the cardiac orifice; they 
varied in diameter from one-fourth of an inch downwards, 
some nearly a line in depth; some of these seemed to be 
raised above the surface, and resembled circular patches of 
glands; they gave a gritty sensation to the finger in some 
places. The pyloric orifice, rough and warty, was 1} inches 
from the cardiac. Between these was a sac, large enough to 
hold a goose-egg, stained by contact with the gall bladder ; 
Which last resembled in shape and size the finger of a glove. 
The pyloric orifice and the duodenum, cut open, were an 
inch wide; the latter very thick and suddenly turned on 
itself; the inner surface consisted of a loose, very movable 
net work 
The intestines were divided into the small intestine and
