In order to observe the development and vitality of chicken embryos before and after irradiation without halting the growth, the eggs were provided with plate glass windows. The results showed that at irradiation doses of 800 to 2400 r, the survival of the 13-somite stage embryos drops abruptly from 98 to 6%. These results had good reproducibility. This sharp decrease in the percentage survival corresponds to the 3.5-day effect in mice. In addition to the reduced survival, a dose-dependent retardation of the morphological development was also observed. (J.S.R.)
