PROTOPLASM OR LIVING MATTER 49 



present around the stamens, mount in water and with the 

 high power observe the protoplasmic movements. Record 

 your observations in a drawing. 



4. If amoeba is at hand observations should be made on 

 the streaming or flowing movements of the protoplasm. 



II. Cib'ary Movement. 



In certain cells, particularly of animals, the protoplasm 

 is extended beyond the free ends of the cells into very del- 

 icate vibratile filaments called cilia. Mount a small frag- 

 ment of the gill of a clam, or the cells scraped from the roof 

 of the frog's mouth, and look for these moving cilia. Possibly 

 the only sign will be in the currents of water caused by the 

 movement of the cilia, the latter moving so rapidly they 

 can scarcely be seen. In a place where the movement is 

 not so rapid observe the direction in which the cilia move 

 and whether they change the direction of movement. Make 

 a drawing.
