Occasionally there occurs in the course of tabes dorsalis paralysis of laryngeal muscles, especially late in the progress of cases attended with symptoms referable to the cerebral nerves. More rarely such a condition appears as a premonitory manifestation, in advance of the typical symptoms, especially the ataxia. Two cases of this latter character have recently been reported by Dr. A. Cahn.1 In one of these bilateral paralysis of the dilators of the larynx was observed soon after the development of rheumatoid pains, pupillary immobility and abolition of the knee-jerks. In the second case there were at first laryngeal crises, followed by the symptoms of paralysis of the posterior crico-arytenoids, tabetic arthropathies and pains and finally ataxia. A study of the cases of like character recorded in the literature shows that in the large majority alterations in the peripheral nerves supplying the muscles of the larynx are found exclusively.
