Using the same methods which brought outthe structure of flagella, the fibrillar nature of these cilia was easilydemonstrated. The Ciliiim. 193 The structure of the large cilia (Fig. 7) is that shown in Fig. o,PI. II*. It is seen that they are composed of a large number of tinetibrils. In life these fibrils are wound together so that the wholea])i)cars perfectly homogeneous. In animals subjected to pressure orkilled in 2 per cent, osniic acid the se^Darate fibrils appear. In ananimal that is breaking to pieces under pressure their fibrillar natureis best seen. (Fig. G.) All the c
