Radioactive phosphorus was diluted with physiological saline and injected after sterilization into yolk sacs of developing chick embryos. The injected eggs were inspected daily by candling for their viability. Dead embryos and hatched chickens were observed grossly. Survival times after injections were longer when smaller doses were administered. Growth retardations of total bodies, small size of spleens, and gonads were observed in groups receiving doses of more than 50 mu c per egg. The embryos that died 1 to 2 weeks after injection showed generalized edematous change. Anomalies of beaks and hind limbs, similar to malformations produced by x radiation, were observed in some embryos which died during incubation. (P.C.H.)
