抄録

In the preliminary paper, we have reported the effect of the anteriorlobe hormone of hypopysis on the artificial oviposition of the Loach and did not draw general conclusions.
Here we report the results of experiments by using other hormone samples prepared from five species of vertebrata.
The results are as follows:
(1) The hormone of Salmon, Onchorhynchus keta, is more effective than others.
(2) The hormone of Catfish, Pseudobagrus aurantiacus, Snake, Flaphe climacophora, Lizard, Takydromus tachydromoides are some effective.
(3) Prae-hormone is uncertainly effective.
