O.- an officer, enjoying habitual good health, and strong constitution, had in his youth indulged in a multitude of excesses which had not, been followed by any appreciable bad consequence. He was irritable, violent, flighty, and so unstable in his talk, that often, in telling a story, he would pass from one to another without finishing any. For a long time he lived carelessly in that fashion; and dark, hypochondriacal ideas gradually took possession of him. He Suffered from constipation and internal haemorrhoids. He was always dejected, and nothing could distract him. In a fall which he had from his horse, he received a severe contusion on the head and on the leg, and was obliged for three months to maintain a horizontal position. The congestion of the head, combined with the haemorrhoidal affection, now increased to such a degree, that he experienced frequent attacks of vertigo and confusion, and could only with great difficulty perform the duties of his office. His pulse was full and slow; his belly distended his countenance flushed He had violent headaches and lumbar pains' had a constant feeling of tiredness; micturition was painful, and the bowels constipated. At the same time, he was in a constant state of mental anxiety. He often clasped his hands, as if he were the victim of the most profound despair; He refused at times to eat or drink, and constantly dreaded that for his neglect of military duty and for his crimes (purely imaginary) he would be degraded and prosecuted criminally, etc. At the end of two months he felt improved, and in two months more was completely restored.
But when his physician saw him again in the commencement of November,
he found him in an agitated condition, occupying a well-furnished apartment.  He observed in him at the same time an extraordinary flow of language, and great agitation of the whole body. Already on the following morning the... exaltation had reached a very considerable height. He got ready to visit the daughter of a superior officer, whom he was but slightly acquainted with, and whose hand he was about to ask. He had already bought a carriage and horse for the purpose of making a long journey with this lady through Europe. He declared himself to be of noble blood, and announced that his promotion was to be very rapid. His happiness was at the highest pitch, and he wished to share it with the whole world. Checked in his desires, he fell intoa fit of frenzy.
Towards the end of November he entered Sieburg. The pupils were somewhat contracted  the haemorrhoidal vessels were swollen  he had pains in the joints; there was a determination of blood to the head; the pulse was rapid. He was very irritable, and easily became enraged. He imagined that he possessed a considerable fortune, and was of lofty station; he believed himself endowed with supernatural power, etc. Every minute he distributes the largest sums of money, afterwards he says that he is God the Father; but if any one asked who his father was, he replied that he was a judge in the court of exchequer; and it was in vain that one tried to show him that he said was absurd and impossible...
