The bees must have worked at very nearly the same rate on the opposite sides of the ridge of vermilion wax, as they circularly gnawed away and deepened the basins on both sides, in order to have succeeded in thus leaving flat plates between the basins, by stopping work along the intermediate planes or planes of intersection.
Now bees, as may be clearly seen by examining the edge of a growing comb, do make a rough, circumferential wall or rim all round the comb; and they gnaw into this from the opposite sides, always working circularly as they deepen each cell.
We directed him to draw out whatever was at the end of that chain; which appeared to be a globe, half silver, and half of some transparent metal; for, on the transparent side, we saw certain strange figures circularly drawn, and though we could touch them, till we found our fingers stopped by the lucid substance.
