Two series of experiments were performed on the Bufo embryo in the later tail-bud stage: the removal of the pronephros from both sides (Series A) and from the right side (Series B). In series A, the tadpoles developed an abdominal dropsy or an unhealthy swollen state. They showed poor differentiation of the intestine and the liver, and the body cavity was filled with liquid which seemed to be secreted from the body wall. In series B, no abnormality was odservable in general growth, and the metamorphosis was accomplished normally. The normal development in the latter leads us to supposition that the pronephros, which was left intact, carried away liquid from the body cavity through the pronephric nephrostomes. This supposition is supported by the ciliated structure of nephrostomes, in both operated and intact animals.
