“11. Stimulation of the central end of a sensory nerve, or of the medulla oblongata, or of the cervical spinal cord, causes a contraction of the renal vessels after _both_ splanchnics have been cut at their point of entrance into the abdominal cavity. Vaso-constrictor influences may therefore pass from the spinal cord to the kidney by some other path than the two splanchnics.
“12. Section of the splanchnic does not always cause an expansion of the renal vessels, a fact which would make it doubtful whether a vascular tonus of the renal vessels emanating from the vaso motor centre or centres in the spinal cord is normally present.
“13. Stimulation of the _central_ ends of the majority of the fine nerves which enter the kidney along with the vessels causes a contraction of the vessels of the kidney.
“14. Stimulation of the _peripheral_ end of each and all of the renal nerves which accompany the vessels causes a contraction of the organ.
“15. After section of all but one of the (usually from 7 to 11) nerves accompanying the renal vessels, stimulation of the peripheral end of the splanchnic or of a sensory nerve still causes a contraction of the kidney which differs but little in amount from that produced by the same stimulation when all the renal nerves were intact, but which takes longer time to show itself after the stimulation.”--Extracts from paper “_On the Mechanism of the Renal Secretion_,” by C. S. Roy, M.D.; read before the Cambridge Philosophical Society, May 23, 1881.
