A lieutenant of Territorials, aged 41 (heredity good, anal fistula at 30, with ulceration of penis of an unknown nature at the same period). In 1907 when off service and married, his wife gave birth to a child; no miscarriages. Had been a good soldier in service before the war. The lieutenant was called to the colors August 2, 1914, and was detached for special duty, for the performance of which he was much praised by the commanding officers. The work, however, was too much for him and on April 1 he had to be evacuated to the hospital with a ticket saying “Nervous depression following overwork in service.” On April 14 he seemed well enough for a convalescent camp, but, apparently through red tape, was sent to a hospital at Orléans. On June 23 he had to be evacuated to the Fleury annex. His eyes were dull and features flaccid; his whole manner suggested fatigue. His pupils were myotic, tongue tremulous, speech slow and stumbling. Knee-jerks were exaggerated and gait difficult, the right leg dragging. Headaches. He could not perform the slightest intellectual work and was the victim of retrograde and anterograde amnesia. He was aware of the decline of his mental power and was fain to struggle against it, becoming restless and sad. The gaps in his memory grew deeper, he became more and more impulsive, even violent, and had spells of excitement. Dizziness and palpitation developed. Sometimes there were auditory and visual hallucinations of such intense character that he tried feebly to commit suicide with a penknife. He fell into semicoma, and then had a number of apoplectiform attacks. W. R. + Apparently the moral and physical situation of the lieutenant was absolutely normal when the campaign began and, as he fulfilled detail duties with absolute correctness for a number of months, Boucherot argues that here is an instance of general paresis _declanché_ by overwork. Syphilis contracted before enlistment. Neurosyphilis aggravated by service. =Case 7.= (TODD, personal communication, 1917.) A laboring man, 42, who always strenuously denied syphilitic infection, proceeded to France eight months after enlistment. He had not been in France three weeks when he dropped unconscious. He regained consciousness, but remained stupid, dull in expression, and with memory impaired. His speech was also impaired. There was dizziness and a right-sided hemiplegia. He was confined to bed four months and was then “boarded” for discharge. Physically, his heart was slightly enlarged both right and left; sounds irregular; extra systoles; aortic systolic murmur transmitted to neck; blood pressure 140:40. Precordial pain, dyspnoea.
