1. The greater portion of the selenium absorbed by rats fromnaturally occurring seleniferous wheat was excreted when theanimal was transferred to a non-seleniferous stock ration. Someof the selenium was eliminated very slowly and appeared to bebound by the body tissues but the greater portion of the seleniumappeared to be eliminated within 2 weeks.
2. Young rats appearedto store more selenium in the body tissuesother than liverthan old rats. Storage in the livers appearedto be similar.
3. Feeding of the toxic ration for only 4 weeks had a depressingeffect upon the body weight of both young and adult rats.
