time reading and in conversation with the other patients. He was perfectly satisfied in his surroundings, frank in his conversation with those about him, and gradually gained more and more insight into his condition. He still persisted, however, in his statements that ether was poured down his back. Said he remembered this distinctly as having taken place while confined in the dungeon. He was then, however, inclined to think that probably they did not have it in for him, and probably they did what they thought was best. In conversation with him today, on June 19, four days after admission, he showed perfectly normal behavior in every respect. Was frank in his statements, spoke of the amnesia mentioned above, and no delusions or hallucinatory experiences or physical symptoms present on admission could be detected. When finally confronted with the picture sent from the War Department for his identification he showed some degree of emotional reaction, stated that the picture was his, but persistently denied ever having been a recruit in the army. On the whole, he took the matter rather lightly and good-naturedly. The history of this attack illustrates a typical case of hysterical psychosis. The marked stupor and confusion, the numerous and varied neurological symptoms, the sensory disturbances, especially the profound anæsthesia to pin pricks, the amnesia and rapid recovery after change of environment, all point to this diagnosis. It is a form of reaction frequently seen in prisoners, and has been designated, for want of a better term, as prison psychosis. At any rate, there can be no doubt as to the genuineness of the symptoms presented by the patient. If we keep in mind that such a type of psychotic reaction is the result of the mutual interaction between an unstable, highly vulnerable psyche and an unfavorable environmental situation--in this instance prison environment--we understand the more readily the later history of this case. On July 16, 1912, he was discharged recovered and turned over to the naval authorities to be returned to prison. Soon after his return to prison he was noted to be melancholy, uncommunicative, was not interested in condition of self or surroundings, had unsystematized delusions of persecution. Physically he was noted to be anæmic, showed general tremors when undergoing examination, reflexes were exaggerated, positive Romberg was present. The physician who accompanied patient to the Government Hospital for the Insane on his second admission stated that on the trip from Portsmouth Prison M. tried to assault a waiter in a restaurant in Boston, accusing the latter of following him. To the physician he said, while on the train, "Take your d---- eyes off me, or I'll brain you."
