“In the inferior zoophytes — such as the Infusoria, Polypi, Medusæ — the whole body seems to exhibit an incessant action upon the surrounding fluid, maintained by means of “very minute and generally microscopic filaments” called cilia, and which apparently serve in the case of these genera not only the purpose of progressive motion, but also of respiration, and of procuring a supply of food.”
