head, is protected by the cranial bones. It 
is milky white except where the blood ves- 
sels may be seen. 
The windpipe connects the larynx at the 
throat with the lungs branching into the two 
bronchi. 
The /ungs, situated in the upper portion 
of the thoracic abdominal cavity, are firmly 
attached to the ribs, in the interspaces be- 
tween which they fit. They are flattened 
and oval in shape, bright red in color, and 
loose and spongy in texture. 
The heart is cone-shaped. The lower 
portion rests between the lobes of the liver. 
The heart is red and is inclosed in a sac 
(the pericardium) that is easily removed. 
The liver, situated a little lower down 
than the heart, consists of two lobes. ‘The 
right lobe is often larger than the left which 
may be cleft at the lower end. The left 
lobe covers the true stomach and part of the 
gizzard. If there is some delay in holding 
a post-mortem examination the edges of the 
lobes of the liver become discolored. Nor- 
mally the color is a purplish red.
