## Abstract The rate at which the cleavage stimulus moves from the mitotic apparatus to the cell surface was calculated from measurements made on flattened, fertilized __Echinarachnius parma__ eggs with excentric nuclei. The time interval between the appearance of furrows in the closer and more dis
Because information concerning the time relations of the cleavage stimulus should prove useful in characterizing both the stimulus and the nature of the response in the cell surface, methods were devised for determining how long the surface must be acted upon by the asters to produce a furrow and th
When the sand dollar egg surface is extensively disrupted by contact with an expanding oil drop, and the egg contents are squeezed out by mechanical pressure, the denuded endoplasm is rapidly covered by a new surface. The original egg surface alters its appearance as the area that it covers diminish
