At the bottom of this spiral-like ciliated funnel is a cell-mouth,which is prolonged a short distance into the protoplasm as the cell-pharynx, and then gradually disappears into the liquid endoplasm. L 146 GENERAL PHYSIOLOGY The cilia of the ciliary wreath of the peristome contract continuallyand rhythmically, and in this way produce in the water a whirlpool,which is so directed that it sucks small particles, such as detritus,mud, bacteria, algae, etc., which are suspended in the water, intothe cell-mouth ; from there, surrounded by a layer of water, theyare shoved by contractions of the body into the cell-pharynx, andthence into th
