Note 196 — Chapter VIII · THE LAWS OF NERVOUS ACTIVITY.
Reading edition
I saw a patient in the Berlin Charité whose face and left hand were in a constant state of convulsive twitching, but no sooner was a scar on the left hand (where the nerve had been divided) firmly pressed than the twitchings ceased, and pain was felt; on removal of the pressure, pain ceased and the twitchings returned.
