Certainly sufficient clinical experience has now been obtained by reliable observers the world over to assign to the prevailing epidemic of influenza a place among the inflammatory neuroses. French, English, German, Italian, Russian, and American writers have noted the prominence, and often persistence of the nervous symptoms, discussing them generally as sequelæ. The initial and concomitant symptoms of influenza are so markedly those of a toxic inflammatory neurosis expending itself chiefly on the nerve coverings, nerve endings, and mucous membranes, that this aspect of its symptomatology and pathology will probably not be gainsaid by any one.
