Our knowledge of this medicine is derived from observations on a worker in a rubber factory, who for weeks had his hands and arms daily bathed in benzine, and drank water impregnated with it. It caused profound disturbance of mind and body; weeping at trifles; irritability; pain darting upwards in occiput. Could not turn eyes upward without severe aching and throbbing. A sort of clairvoyant state, in which a great white hand appeared to him in the darkness, coming outspread towards his face, causing him in terror to scream for the watcher. A sense of falling through the bed and floor. Insomnia and photopsic illusions. Pains travel from below upward (headache, pain in anus); also chills.
