. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. PLATE I EXPLANATION OF FIGURES All figures are photographs of Arbacia eggs fixed in Bouin's solution and stained in Heidenhain's hematoxylin. All except Fig. 3 have been treated with molar concentration of colchicine. FIG. 3. Metaphase stage of control egg showing a typical mitotic figure. FIG. 4. Egg in same stage as Fig. 3 when treated with colchicine. Note effects on the mitotic figure. FIG. 5. Egg in prophase stage when treated with colchicine. A liquefaction of the spindle and asters have occurred as in Fig. 4. F

A liquefaction of the spindle and asters have occurred as in Fig. 4. FIG. 6. Later stage in the mitotic cycle showing destruction of asters and spindle after the chromosomes have separated. No cleavage furrows formed in this egg. FIG. 7. Egg from same batch and treated in the same way as Fig. 6. Here the cleavage process occurred after the egg was placed in the colchicine solution.
