When eggs of Coccophora Langsdorfii, Fucus evanescens, or Sargassum confusum are treated with zinc chloride solution at a densinty higher than 25per cent, clear blisters are formed over the egg surface. After the morphological polarity was determined, plasmolysis occurs with zinc chloride so that the protoplasm is separated from the cell wall and the blisters appear in the space between the plasm and the cell wall. This indicates that the cell wall has been hardened parallel with the po larity determination. The blisters seem to be composed of the hyaline plasm extruded through small holes of the plasma membrane brought about by treatment with zinc chloride.
