At the request of the organization committee, we have reviewed our cases of epidemic encephalitis occurring during the past year, with a view to the discovery of novel symptomatology or disease incidence which might be of either diagnostic or pathologic interest. It has always, of course, been clear that an infection flung far and wide through the nervous system would inevitably produce in different persons extraordinarily diverse clinical pictures. In epidemic encephalitis the diversity observed becomes greater with increased experience, and we have been fortunate enough in the neurologic department of Bellevue Hospital to find many examples of disease incidence in the sensorimotor system both central and peripheral, and, we believe, in the vegetative nervous system as well.
We have grouped cases in this paper under the headings: spinal types, disturbances of metabolism, disorders of motility and symptoms evidencing impairment of the vagosympathetic mechanism. The cord syndromes which have been
