You may remember that we called the Anemone a cousin
of the Jelly-fish, for they both belong to the same lowly division of
the Animal Kingdom.
Animals have queer ways of getting a living. Who would expect to find
millions of poisoned darts in a Jelly-fish? Who would guess that these
weapons are coiled up, ready to spring out at their prey? Men have made
many weapons for killing, from the bow-and-arrow to the torpedo, but
none of them is more wonderful than the weapon of the Jelly-fish.

1. Where is the mouth of the Jelly-fish placed?
2. How does the Jelly-fish move through the water?

LESSON X.
SHELLS AND THEIR BUILDERS (1).
THE PERIWINKLE, WHELK AND LIMPET.
Most of the shells which you find scattered over the shore are empty.
The little animals which built them are gone; and their empty houses, of
wonderful shapes and colours, are all that you find.
