=Case 59.= (PELLACANI, March, 1917.) A Milanese workman, 28, was exposed to the sun on sentry-go and had an attack of convulsions, on awaking from which he found himself in hospital. He always had attacks in reaction to emotion. One day, in a quarrel provoked by jealousy concerning a prostitute, he apparently lost his mind, whipped out a hunting-knife, and wounded a comrade. Thereafter he lay unconscious until the next day. The court-martial decided that he was not fully responsible. Eventually, he was sent from the front for having insulted and struck a superior officer. The report read also that he was a prey to delirium and had frothed at the mouth. In the interior he had convulsive attacks, with falling and loss of consciousness. He told of arguing with a sergeant about a bicycle, of seeing darkness before his eyes like a veil, and of subsequent amnesia. In hospital he had intense headaches at times, with spells of sullenness, hostility, and complaints concerning nurses and attendants and other patients. At other times, he was quiet and comfortable. One day he went into an excitement and wept, asking to be sent back to the army, striking the table with his fist and head. He then screamed, flew into a passion, and fell to the ground in semi-stupor, shaking his body and trying to kick and knock away those who intervened. He was placed in bed but remained agitated and unconscious, with anesthesia and frothing at the mouth. The abdominal and cremaster reflexes were absent in this attack, and the pupils were rigid and myotic. The pulse was rapid and the blood pressure high. Afterwards he was sleepy, stupid and weary, and showed fine rapid tremors of hands, tongue, and eyelids. The abdominal reflexes now returned in excess, and a marked dermatographia developed.
