A soldier, Colonial, 29, was twice in the 6th Army neurological centre. The first time, February, 1916, he was under observation for astasia-abasia, having been invalided twice for this disease,--once in 1915. This man had had syphilis at 21, and was then taken care of at Saint-Louis Hospital and at Cochin. A volunteer for the duration of war, September, 1914, he had intermittent disorders of station and walking, which caused his invaliding January, 1915. As the trouble stopped, he asked to go back to the front in September, but the same difficulty reappeared with fatigue, and he was sent to the army neurological centre. When standing, there was a ceaseless trembling of the whole body but especially of the legs, with tendency to propulsion. In walking also, there was a trepidant abasia, sometimes dizziness, and even a sudden fall. Standing on one foot he trembled and fell. Examined on his back, muscular strength was found intact in all limbs, and there was no trembling or incoördination or intention tremor in the performance of any movements, though there was a slight trembling of the raised fingers and hand. Reflexes were normal. The right pupil was dilated; the left pupil reacted sluggishly. There were lateral nystagmiform movements to the left. Caloric nystagmus appeared from the right ear in 15 seconds, from the left in 30. Rotatory nystagmus appeared in 35 seconds on both sides. Lumbar puncture yielded a fluid with a slight lymphocytosis; albumin, .3 grams; chloride, 7.30; sugar normal. Rest in bed improved the astasia-abasia, and the man was sent back to his corps, February 20, 1916. He came back March 16, having had a dizzy spell, with suffocation feeling and a fall, whereupon the trepidant astasia-abasia had reappeared. There were none of the so-called defensive reflexes. The neuromuscular excitability of gastrocnemii was less on the right than on the left. A von Graefe sign was sometimes found; no diplopia save on looking far to right. Lay reflections on syphilis: Suicidal attempts. =Case 32.= (COLIN and LAUTIER, July, 1917.) A man was called to the auxiliaries at the outbreak of the war, and served as stretcher-bearer at the Marne. He then became an attendant at the Grand-Palais. Acquiring gonorrhoea, he was cared for but he grew depressed. The blood was examined and the W. R. found positive. The physician immediately made known the result without circumlocution, and knowing vaguely that the W. R. meant syphilis, the patient felt an irresistible impulse to suicide, and cut his throat. It seems that he had often before said that if he got syphilis he would kill himself. Recovering from his wound, he was invalided to Villejuif, Sept. 19, 1916, breathing through a cannula and responding to questions in writing. He had always been a nervous and emotional man, a farmer in Auvergne; he was married and the father of several children.
