a doubtful amphibious Animal of Germany. 251 
fastening this part of it, like the ligamentum suspensorium in 
other animals, to the muscles of the body; a similar mem- 
brane connects the liver, underneath, with the parts contiguous 
to it. 
The longer blood vessel mentioned in the description of the 
heart, after having formed the enlargement already spoken of, 
forms a double one on the upperpart of the liver ; then runs down 
on the right edge of that viscus, giving out some small branches 
to its substance, also one to the mesentery; and terminates 
upon the surface of the fifth lobe of the liver, in a great ramified 
branch. The colour of the liver is a dark bluish-grey, with 
numerous small black spots : its substance is glandulous and 
compact, more so than I have observed in other analogous 
amphibious, animals, or fishes. 
The gall-bladder is pretty large, so as to fill up the whole 
cavity formed by the lobes of the liver, to which it is, in some 
places, firmly attached, as it is, underneath, to the first intes- 
tine ; thus having an immediate connection both with the liver 
and the intestines. 
The oesophagus is a narrow canal, of about one inch in 
length : it runs down on the back ; is strong, and internally 
full of longitudinal wrinkles, particularly as it approaches the 
stomach, at the orifice of which they form a perfect cardia. 
The stomach is entirely distinct from the oesophagus and 
bowels, being infinitely wider. It forms a bag, about two 
inches long, of a strong and almost coriaceous appearance.* 
Its lower end terminates in a narrow duodenum, which con- 
tinues nearly straight for about two inches, forming the small 
intestines, then making three considerable convolutions, and 
* In the stomach of one specimen, I found the head and bones of a small fish.
