The Muscles 1i7 
To the sternum as to the ribs is only a small 
part of this muscle attached. 
Between the two above described muscles is 
found a space which is filled, in great part, with a 
fibrous membrane that binds the two muscles 
together. This membrane begins very thin and 
without a marked boundary behind the kidneys; it 
runs forward directly under them and the dorsal 
wall of the body, becoming gradually thicker,though 
never very thick, and fuses, laterad to the kidneys, 
with the above-mentioned aponeurosis of the two 
diaphragmaticus muscles. Thence this aponeuro- 
sis goes to the upper, hinder side of the liver where 
it becomes fairly thick. One thus finds in front 
of the stomach a fibrous membrane, belonging to 
the diaphragmaticus, which is pierced by the 
oesophagus and by a fairly large space that extends 
around the cesophagus and between it and the 
liver. This membrane fastens the liver to the 
cesophagus. 
The muscle of the right side is covered, on almost 
its entire inner surface (from its hinder end to the 
liver) by the belly-like skin, and is fairly closely 
united withit. The left muscle, on the other hand, 
is only covered by this skin from the hinder border 
of the stomach forwards; farther forward it lies 
immediately on the under and left side of the stom- 
ach and is united with it by loose connective-tissue. 
Outwardly both muscles are united by a thin layer 
of connective-tissue to the true abdominal muscles.
