8 Messrs. Hancock and Embleton on a Gymnetrus 
blunt blind extremity, Pl. II. figs. 2 & 3c. The canal in which 
the cecal prolongation is lodged is prolonged for an inch or two 
beyond the end of this latter, and contains several small blood- 
vessels, and the cellular coating of the caecum arranged in cords, 
the vessels being gradually lost by passmg backwards and out- 
wards into the surrounding museular tissue, the cellular cords 
being attached to the sides of the termination of the canal. 
The anterior main part of the stomach, when laid open, was 
quite empty, the inner surface of the cesophagus and stomach as 
far as 2 in. below the pylorus perfectly uniform and smooth ; 
from the point here indicated, the upper wall of the stomach 
preserits the gradual beginnings of a few longitudinal plice, on 
tracing which backwards they are found to increase in number 
until at 5 in. m front of the anus the whole inner surface of the 
tube is provided with them. They are continued on in the 
stomachic caecum to within 2 or 3 inches of its termination. At 
about halfway along this caecum: was found a small quantity of 
the spawn of some fish partially digested, several of the ova being 
still entire ; a little way in front of these was an angular bit of 
cinder. 
The pylorus, fig. 3d, coming off as above mentioned from the 
most enlarged part of the stomach, extends for only 1} in., when 
it becomes suddenly constricted and presents internally the usual 
circular valve. 
The duodenum, figs. 2 & 3e, beyond is a cylinder of about 
1 in. in diameter and 1 ft. in length, perforated all round by 
very numerous circular openings, the orifices of the pancreatic 
ceca, which measure about } inch in diameter and 1 inch in 
length, and completely mask the whole duodenum. This part 
of the tube extends forwards, lying parallel to and beneath the 
stomach, and overlapped by the posterior lobes of the liver fur 
about 4 in., and then emerging as it were from the pancreatic 
ceca is continrous with the remamder of the intestine, figs. 2 & 
3 ff, which then is saddenly bent backwards and runs along the 
lower border of the pancreas obscured by the ceca of the nght 
side, and then keeping along the floor of the abdominal cavity it 
passes on as a straight tube to the anus, figs. 2 & 3g, at the 
front of which it opens separately. The diameter of the duode- 
num is diminished one-half at its exit from the pancreas, and the 
intestine continues of the same size to within an inch or two of 
the anus, where it is gradually lessened to about 1 inch. The 
length of the mtestine from duodenum to anus is3 ft. 5in. The 
inner surface of the intestine below the duodenum presents a 
very delicate honeyeombed texture, the lamine being fine, of 
varying size, and crossing each other in all directions, the largest 
standing up pretty high and taking a longitudinal course. This
