In Reply.—  We do not believe that the omission, by name, of pertussis or specific parasitic infections made our discussion of the etiology of cough incomplete. Since "cough can be produced by a multiplicity of diseases located in a variety of anatomic locations," we believe that a listing of every disease entity that causes cough would serve no useful purpose. Pertussis and parasitic infections were included in the general statement, "any infectious process... involving the trachea or bronchi may trigger the cough reflex." In fact, reference 84 in our review describes a case of chronic cough due to Syngamus laryngeus infection, which is a parasitic disease of the larynx and tracheobronchial tree. If we had intended to produce a list of parasitic infections of the lung that may cause cough,1 we would have had to include Trichuris trichiura, Enterobius vermicularis, Ascaris lumbricoides, A suum, Ancylostoma duodenale, Necator americanus, Trichinella
