250 Dr. Schreibers’s Description of 
owing to the length of time the specimens had been kept in 
spirit. 
On account of the connection of the parts, I shall proceed to 
describe the liver, leaving the respiratory organs at present. 
The liver is the most considerable viscus of this animal, and 
is nearly five inches long, beginning about one inch below the 
heart, running down to the larger intestines, and terminating 
about two inches above the anus. Five lobes may be distin- 
guished; the uppermost begins narrow and pointed, and is 
somewhat divided by a longitudinal ridge, just where the oeso- 
phagus terminates in the stomach. 
This lobe is the longest and narrowest, is cylindrical, and 
runs down on the right side of the body, covering half the 
stomach, near the end of which it extends to the left, and forms 
the second lobe, s which is throughout connected with the former, 
and with it fills up the whole cavity of this part of the belly. 
This second lobe terminates in a third, which lies deep in the 
left side, is of an oval form, with a pointed end, and has several 
incisions on its edges. 
The fourth, a very small lobe, is formed on the under edge 
of the first, and only marked by two incisions, caused by the 
cavity in which the gall-bladder lies. 
The fifth lobe is the broadest, as it fills up the whole breadth 
of the body : it is almost quadrangular ; terminates in a point to 
the right, and goes off in an oblique direction to the left. 
The upper surface of the liver is smooth and convex, the 
under one somewhat rough and concave. On the upper sur- 
face are transverse elevations like ribs ; and a thin membrane 
runs from the pericardium, along with the blood vessel, to its 
beginning, and over the middle of the first lobe to the second.
