By applying the double diffusion technique of Ouchterlony and the immunoelectrophoresis, sequence in the appearance of antigens reactive with antisera against HbCOs from 5‐day embryos and adult chickens, and the major component of adult HbCO in the course of chicken development has been studied. Antigenic components reacting to antiserum against HbCO from 5‐day embryos have been detected throughout development. Three globin‐like components specific to early embryos are detectable in embryos to 2 days of incubation. Two Hb components are detectable in embryos from 3 to 5 days of incubation; one is apparently specific to embryos, while the other seems to be somewhat different from adult Hb. After 6 days of incubation only one adult Hb component is detectable. Antigenic components reacting to antiserum against HbCO from adults have also been detectable throughout embryonic life. One globin‐like component specific to early embryos can be found in embryos to 2 days of incubation. One or two Hb components which are probably specific to embryos can be detected in embryos from 3 to 5 days of incubation. After 6 days of incubation one adult Hb component is detectable, while one globin‐like component specific to adults can be found after 15 days of incubation. Further, the other globin‐like component is detectable after 3 days of incubation. Antigenic components reacting to antiserum against the major component of adult HbCO have been detected throughout development; one which seems to be somewhat different from either adult Hb components can be found in embryos from 2 to 5 days of incubation, while the other which is identical with the major component of adult Hb is detectable after 6 days of incubation.
