SUMMARY 



A brief general note on amoebae is given, and 

 the characters of the type we have employed 

 are described. 



Special methods of examination suitable for the 

 study of the action of chemical agents on amoebae 

 are shown. 



The advantages of the jelly method are pointed 

 out, and in-vitro staining of the amoeba while it 

 is alive is explained. 



The stages of nuclear division of the amoeba are 

 shown by the jelly method of staining. 



The characters of the movements, and the modes 

 of nutrition of the amoeba are described in detail. 



The methods of reproduction of this amoeba, 

 so far as they have been observed, are compared 

 with those which have already been described in 

 other species. 



The process of conjugation has been watched, 

 and results in the production of numerous minute 

 amcebulse. 



The occurrence of a long, slender variety of the 

 amoeba has been observed, and its possible signi- 

 ficance has been touched on. 



The action of auxetics and kinetics in hastening 

 multiplication has been demonstrated, and the 

 effect of one of the former (tyrosin) in producing 

 multinucleate forms is explained. 



The so-called " radiosa " types of amoeba have 

 been produced by the action of auxetics and 

 kinetics.
