The hydroids are compound animals which produce in-dividuals ; and these individuals in their turn produce com- HYDROIDS, MEDUSAE, ETC. 151 pound progeny. Some of them look like shrubs, youngtrees, or bushes, and only minute investigation proves themto possess vitality, and to be in fact communities of indi-viduals arranged in a plant-like form; from these may behatched a single jelly-fish or medusa, and from the medusawill eventually be produced a group of hydroids. The hydroids belong to the division Acalephce, and areas a general thing semi-transparent, fragile, and often verygraceful objects, yet not always so harmless as they look. In
