THE COMMON CORMORANT. 
133 
The heart is triangular, depressed, obtuse, 2§ inches long, its greatest 
breadth 1 T V The liver has two very unequal lobes, the right 5 inches, the 
left 3 inches long; the former 2£ broad, the latter 13. The gall-bladder is 
2i long, itt diameter, rounded, but not much enlarged at the extremity. 
The oesophagus is 22§ inches long; at its upper, part when dilated upwards 
of two inches wide, extremely thin, its circular fibres distinct. It is con- 
tracted in the whole length of the thorax, where its smallest diameter is T 8 2, 
the largest ; but this part, which in the ordinary state has its inner coat 
folded into numerous longitudinal wrinkles, is capable of being dilated so as 
to present a diameter of more than 3 inches, when the internal rugae dis- 
appear. The proventriculus seems at first to form part of the stomach ; 
its walls are extremely thick and studded with glandules, disposed in two 
circular patches, which are separated by a space of about T 3 2 of an inch. 
The stomach properly so called is very small ; its muscular coat thin, but 
with two distinct tendons. It is of an oblong form, compressed, and at its 
upper parts has a rounded lobe, from which the intestine comes off. The 
inner coat is thick, soft, and rugous. The pylorus has a circular marginal 
rim. The intestine, which is 8 feet long, is at its upper part in diameter, 
towards the coeca ff . The rectum is 7 inches long, its diameter for 4i 
inches is r 7 ?; the cloaca globular, 2 T 2 2 in diameter; the coeca -,- 3 2 long. The 
cystic duct enters one inch below the hepatic ; between them enters one 
of the pancreatic ducts, the other 2 inches farther up. The distance from 
the pylorus to the hepatic duct is I65 inches. 
The lungs extend to the kidneys. The ovules exceedingly small and 
numerous. In the proventriculus and lower part of the oesophagus were 
many small ascarides. The contents of the stomach were a few bones of 
fishes. 
Although I have not actually observed that Cormorants have the power 
of disgorging such substances as they are unable to digest, I should not be 
surprised to find this to be the case, when their habits are investigated in 
a state of domestication.
