Area below the diagonal line represents deposits by the mantle-shell preparation on a coverslip fragment over a period of 62 hours. The coverslip was inserted between the mantle and the shell 74 hours after its isolation. The marginal fibrous zone is clearly dis- tinguishable, but the other two zones cannot be easily distinguished without the aid of the polarizing microscope. FIGURE 3.
