September 14th:--Patient was today discharged by a jury, as not insane. He presented a normal appearance upon leaving the Hospital. Insight was good, and there existed a total amnesia for the period between August 19th, when he was arrested, and September 3d, when he recovered from his stupor. This case illustrates in an excellent manner the development of a mental disorder as an immediate consequence of a situation strongly affective in nature,--in this instance, threatened imprisonment for a grave offense. The emotional shock of the arrest called forth in this, to all appearance, previously normal individual, a marked excitement accompanied by hallucinations and fleeting delusional formations. This excitement, which required the application of constant restraint, was followed by a stuporous state and total clouding of consciousness. Upon being removed to a hospital, and surrounded by a new environment, patient gave evidence, after a sojourn of only a few days, of the salutary effect of such procedure. On September 3d, ten days after admission, the stupor disappears, and the only residue of the one-time psychosis is a complete amnesia for the entire period. The amnesia and the hypalgesia, which the patient manifested on admission, are the two symptoms which may perhaps be considered as more or less hysterical in nature. Aside from this, it is difficult to see wherein the psychosis resembles an hysterical disorder. Another point which should be mentioned here in passing, and which will be dilated upon later, is the medico-legal importance of this class of cases. This patient was wanted for assault and robbery in an adjoining State. Upon his admission to this institution an inquiry was received from the U. S. Attorney for the District of Columbia as to the probable duration and course of this man's disorder, as they had in possession extradition papers from the authorities of the State in which the crime was committed. It was only by recognizing the nature of this disorder that we were able to furnish the authorities with intelligent information concerning the prognosis of the case, and which the course of the disease corroborated in every detail. By recognizing the fact that these disorders are consequences of the criminal act, the possibility of considering the man insane at the time of the commission of the act is obviated in a large measure.
