 At the end there are formation 

 and dissolution of many multipo- 

 lar cells. The shock affords a new

 zid drop. (Theory of the division

kinds of amaeboid movements and

 little drops have an ascending mo- 

 vement, in zig zag. 



CONCLUSIONS- 



1. Movements, structure and most of the physical proper- 

 ties of protoplasm can be imitated with alealine oleates. 



2. Alveolar structure can be imitated with soaps, oil and 

 sugar (Butsehli) or oleates. The structure observed by Kuns- 

 tier can be reproduced with oleates and peptone. 



3. Vibratory, amaeboid and infusorial movements, be- 

 sides internal currents, plasmodium, empty nucleus, nuclear 

 filaments, can be imitated also with oleates or caprates. 



4. Structures, movements and evolutions results of imbi- 

 bition, osmotical and chemical currents. Chimiotropism is 

 evident in drops of oleic or eapric acid in an alealine solution. 



5. Natural protoplasm might be a salt of albuminoids, a
