    ON THE DISTEIBUTION OF SENSOEY DISTUE- BANCES, WITH ESPECIAL EEFEEENCE TO THE PAIN OF VISCEEAL DISEASE.^ BY HENET HEAD, M.A., M.D.(UNIVEESITY COLLEaE HOSPITAL). In the paper to be read before the Neurological Society, I hope to prove the following points 1. The pain caused by visceral disease is distributed over certain definite regions, and is frequently associated with cutaneous tenderness. 2. This tenderness maps out certain areas on the sur- face of the body, which are characterised by the following- points ;— ® (a) They do not overlap. {b) The reflexes obtained from them are exaggerated. 3. The distribution of herpes zoster marks out the same areas as those which are tender in visceral disease. _ 4. Each of ^ these areas represent the distribution of the pain fibres which come off from one segment of the spinal cord m one posterior root. Thus each area can be called by the number of the spinal root it represents. 5. Each organ causes pain and tenderness along one or more root areas, and I shall take the various organs one by one, showing the root areas with which each is particularly 6. If all the areas which are ever found to be tender in cw'nfTr f placed together on a chart of the body, two gaps are seen-one on the arm, the other on the front of the thigh or leg. peritoneum cause local, but not referred, pain. The tenderness is not truly cutaneous Read at Cambridge as a thesis for the Degree of M.D., Juno 9th, 1892.
