At the neurological center, which he entered December 17, his gaze was fixed and there was a slight exophthalmos. The folds of the face were smoothed out. The nose was deep set (as a result of a fall at the age of eight). In the upright position he could not remain still, but trembled markedly on the left side, so that he had to make a few steps to keep his balance. He was unable to stand on his left leg. He walked on a broad base, in little steps, and rather unsteadily on account of tremors augmenting upon movement. General muscular weakness; left hand slightly weaker than right. He could not lift both legs more than 20 cm. from the bed and in the process they both trembled, trembling together. There was also intention-tremor of the arms, a little less marked than that of the legs, of an irregular rhythm. The arms trembled as a whole. In a state of rest there was no tremor. There was a slight muscular stiffness and the patient himself felt difficulty in relaxing. Patellar reflexes absent, even on reinforcement; Achilles jerks absent. Speech monotonous and tremulous, but not scanning; syllable doubling observed by the patient. Manuscript tremulous and, on account of tremors, illegible. Hypalgesia of legs, more marked distally. Deep sensibility of tendo Achillis and patellar reflexes lost. Pain on compression of eyes diminished. Formication in arms. W. R. of blood negative. Slow improvement followed and the patient left the neurological service May 4, 1916, able to walk more easily and without tremor. The knee-jerks and Achilles jerks were still absent. We here deal with a syndrome in part that of a multiple sclerosis, that is, the intention-tremor, gait disturbance, muscular rigidity, and weakness. _Re_ multiple sclerosis, Lépine remarks that there are numerous army cases of pseudo multiple sclerosis which are actually hysterical or hystero-traumatic cases of hypertonus and tremor. The true cases of multiple sclerosis, according to Lépine, are of interest inasmuch as they are usually found in officers. These men have apparently at first but a slight motor disorder, quite compatible with desk work. We have usually under-rated the cortical element in multiple sclerosis. Spells of confusion, delusional ideas, sometimes grandiose, start up without warning in these cases. To be sure, alcohol and syphilis sometimes also enter these cases etiologically. Any case of localized tremor ought to be carefully examined psychically, and such cases in general ought not to be given responsibility.
