CHANGES IN THE PERCENTAGE OF CALCIUM AND PHOSPHORUS OF THE BLOOD FOLLOWING SECTION OF THE SYMPATHETIC AND VAGUS NERVES.
When a splanchnic nerve or the celiac plexus was severed a definite fall in serum calcium resulted, the level falling to 6 mg. per cent and remaining low for 1 or 2 weeks. Tetany, however, did not develop. The inorganic phosphate was slightly altered. On the other hand, when the vagi nerves were severed, the serum calcium rose. The equilibrium of both calcium and phosphorus was rendered less stable by the division of the sympathetic or the parasympathetic nerves.
