THE INFLUENCE OF ENVIRONMENT 

 AND THE ACTION OF AUXETICS 

 AND KINETICS ON AMOEBA 



Introduction. For the benefit of those who are 

 not acquainted with the nature of experiments on 

 individual cells, we think it advisable to give a 

 short general description of an amoeba, so that the 

 kind of cell on which the researches have been 

 carried out will be better understood. An amoeba 

 is a unicellular organism belonging to the group of 

 those low forms of animal life which are known as 

 protozoa. It has a widespread distribution and 

 may be found in a variety of situations such as 

 water, damp earth, etc., and in the bodies (usually 

 the intestinal tract) of many animals and of man. 

 In the latter situations certain varieties of amoeba 

 may produce disease, but the large majority of the 

 known species appear to be harmless. From the 

 fact that distinct differences in structure and life- 

 history can be made out between many of the 

 individual amoebae, it has been possible to establish
