Having thus fully described the mode of origin of what may be termed the sexual organs in Vaucheria, the author proceeds to describe the process of impregnation as it takes place in the Fucaceæ, and which he finds to be of a precisely analogous nature. Adverting to Thuret’s observations and experiments, which showed that unless brought into contact with the antheridia of the male plant, the spores of these plants invariably perish without germination, he proceeds to relate his own researches on the same subject in Fucus vesi-culosus. The result was fully to confirm Thuret’s statements.
