animal. Being cut open, it measured transversely 1} inches 
on an average, 9! inches at the upper or largest part, and 
2 inches at the largest part of the rectum. |. Valvulee conniv. 
strongly developed, except in the last 10 or 12 feet, and most 
so in the upper part; the valves were transverse, instead of 
being oblique as in the whale; and it is remarkable that 
G. Cuvier should not have mentioned these in the globiceps, 
when he is speaking (Anat. Comp.) of the longitudinal folds 
in the intestine of the porpoise and the dolphin; neither is 
anything said by Mr. Hunter of marked transverse rugze, nor 
by F. Cuvier, nor Lesson, so far as I have seen. In the last 
10 or 12 feet, the mucous membrane was in irregular folds, 
more longitudinal than transverse. No Peyer's nor other 
glands seen. Muscular coat thick, the longitudinal fibres 
being quite marked at tlie upper part. The intestine termi- 
nates at last, not directly upon the surface of the body, but 
In a fissure eight or ten inches in length. 
The right lobe of the liver was from two to three times 
as large as the left. The vena cava passed in a groove behind 
the organ; umbilical vein pervious, opening freely into the 
vena porte, but seemed to be gradually obliterated towards 
the umbilicus. The hepatic duct ran directly to the intes- 
2 then turned abruptly, and ran along the dilated portion 
of intestine, forming a part of its parietes, and opened just 
E = contraction between this portion and the proper in- 
testine. The duct was considerably larger where it turned 
than at first, measuring about half an inch across when cut 
pen ; continued large and thick in the parietes of the intes- 
tine, but without any dilatation. 2 gor 
- The pancreas was a well-defined organ, 2 by 4 inches in 
extent, white, quite soft, but glandular as in man. The duct 
"Pened into the hepatic, where it turned, and was 7 lines 
“cross when cut open in the substance of the gland. - 
Spleen connected with first cavity of stomach; a dark red, 
very firm organ, of a flattened spherical form, about 4 inches 
in diameter, and 1i inches thick; also two smaller, supple- 
mentary organs.
