Out of the right fob hung a great silver chain, with a wonderful kind of engine
at the bottom. 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

drawn, and thought we could touch them, till we found our fingers stopped by
the lucid substance.
