The weight of the bursa of Fabricius of chicks hatched from eggs dipped in a 0.67 percent solution of testosterone propionate in ethyl alcohol was significantly reduced. Also, bursa weights of offspring one and two generations removed from the chickens hatched from the dipped eggs were significantly reduced. The change appears to be cytoplasmic.
