This dose was repeated January 2 and January 3, on which date there was no headache. January 4, Kernig’s sign and neck stiffness were diminished; fine râles at the bases without dulness. 30 cubic centimeters of electragol were injected intravenously. January 5, Kernig and neck stiffness slight. Meningitic tâche; exaggerated knee-jerks; unequal pupils; temp. 36.6 morning, 39.4 afternoon; respiration 36; pulse 120; no râles; splenic enlargement. 6, no headache or photophobia; constipation; fine râles, right base; spartein; meningococci found in hypertensive spinal fluid. 30 cc. serum. 7, more râles; exaggerated heart sounds; intestinal worms in stools. 8, temperature fell to 37; pulse to 90. 9, patient worse; involuntary stools; Kernig’s sign; stiff neck; fever. 30 cc. serum injected. 10, 20 cc. injected. 11, delirious all night; tetaniform stiffness of neck; more râles. 12, delirious, incoherent words, Cheyne-Stokes breathing. 13, less stiffness, Kernig almost absent; pupils normal; Romberg sign slightly developed; pulse 120. 14, a few râles at right base. 15, pains in elbows, knees and hands with joint swelling; moist râles; temp. 38.4; pulse 140. Digitalon. 16 and 17, serum erythema of thorax; edema of left knee; pulse 150; spartein 16. 17, ice pack over heart. 18, edema of knee diminished; no headache, delirium or pupillary sign. 19, improvement. Temperature normal thereafter. 20 and 21, fine râles. Then all symptoms disappeared. Recovery was predicted, but on January 28 it was observed that the patient was untidy, made mistakes in dressing, such as trying to put his legs into the armholes of his shirt, and denied the most evident facts: His _képi_ on his head, he said it was not. Face drawn; skin yellow. Appearance of asthenia. Deep depression and hebetude. At this time the knee-jerks were exaggerated, pupils unequal, vermicular tremor of tongue; the patient walked on a broad base with tremulous legs suggesting contracture and weakness. February 8, in a similar state the patient wandered about his room, moving his bed and chairs about, answering questions with an absent air. He had now been taught to be less untidy. March 5, stiff neck and Kernig’s sign were distinct. He made believe he was on his farm. Ecchymosis of right upper eyelid: he had fallen (his sheep had pushed him over!). The improbability of this idea did not persuade him to think it had not happened. He walked after the manner of a tabetic. In April he became bedridden, unable to walk, with marked stiffness and Kernig’s sign. He had at this time periods of excitement in which he would tear the bedclothes. He was invalided as demented.
