In the neck it only forms three neck knots, from which arise the ! 
heart nerves and lung net-works, which send nerves to the heart and 
lungs. In the chest there arise five branches from the third, fifth, 
seventh, eighth, and ninth knots, which descend in the course of the a 
vertebre and pass through the diaphragm, where they unite on each : 
_ side into one trunk, the bowel nerve, which soon unite together, and — 
_ form the great half moon knot, from which nerves are given off to — 
all the abdominal viscera, forming ten net-works, which communis 
_ €ate with one another, and are named after the adjacent viscera, 
_ wiz: the stomach net-work, near the belly artery, supplying the 
stomach ; the spleen, liver, the upper, middle, and lower mesente- 
ric net-woiks, two kidney, and two spermatic net-works.
