THE isolation from the nasal passages
 of chickens with infectious colds or
 coryza of a small bacillus with which a
 coryza of short duration could be produced
 in healthy chickens has been reported by
 de Blieck (1932) in Holland, by Nelson
 (1932) in New Jersey, by Delaplane and
 Stuart (1934) in Rhode Island, by Eliot
 and Lewis (1934) in Maryland, and by
 Schalm and Beach (1934) in California.
 Nelson stated that the bacillus failed to
 grow on open blood agar plates but did so
 when the plates were sealed with clay. De
 Blieck, Delaplane and Stuart, and Eliot and
 Lewis experienced no difficulty in growing
 their organisms aerobically on blood agar
 but the latter stated that growth was fav-
 ored by incubation in an atmosphere con-
 taining an excess of carbon dioxide. Schalm
 and Beach, however, obtained no growth of
 the organism under aerobic conditions but
 succeeded when they employed an atmos-
 phere with 10 percent carbon dioxide.
 Nelson, Delaplane, and the writers ex-
 changed cultures and compared their re-
 quirements for growth. Nelson (1935) re-
 ported that both Delaplane's and the writ-
 ers' cultures behaved in his laboratory like
 his own and that his culture in Delaplane's
 laboratory grew on aerobic plates in the
 same manner as Delaplane's cultures. The
 writers (1936) found that all three cultures
 colonized not at all or very meagerly on
 blood agar under aerobic conditions but
 grew satisfactorily when air was excluded
 by sealing the plates or tubes with clay or
 when they were incubated in an atmosphere
