Therefore, when the cell has, let us say, quadrupled its original mass, but by no means quadrupled its surface, difficulties set in, waste begins to gain on repair, anabolism loses some of its ascendancy over katabolism. At the limit of growth, then, the cell divides, halving its mass and gaining new surface. Of course surface may be increased by out- flowing processes, just as that of leaves by many lobes ; and "
