The histological effect of irradiation on 11-day-opd chiek enmbryos was investigated, After receiv'ing 800 r. all embryos died in 24 hours after the irradiation, after 700 r 505 died in 48 hours, and with 100 r all 500 embryos survived. x irradiation caused v'acuopar degeneration and infiltration in the ectoderm; pyknosns, swelling, edema. and disappearance oi cell projections in the i'csodcrm; and hyalinization pn the endoderm. These pathological changes were of approximately the same degree aiter l0, 50, ur 600 r. Howev'er. after the lower doses of irradiation. i-egeneration started earlier but was more gradual than that seen after large doses, Regeneration started suddenly 24 hours after irradiation with large doses and then progressed rapidly.
