Different problems arising from the artificial insemination of amphibians have been investigated onTriton alpestris. The influence of the following factors was tested:—

(1) The length of time between insemination and the addition of water. (2) The length of time between the withdrawal of the eggs from the oviduct and the insemination. (3) The degree of dilution of sperms. (4) The temperature of eggs and sperms respectively. (5) The cœlomic fluid.

We determined for every experimental series the total rate of insemination, the degree of “polyspermy”, and the course of the cleavages.
