 Kelvin, the great physicist, apply: 'No hocus-pocus 

 of electricity or physics could make a human cell/ 1 



Rhumbler also certainly a reliable and creditable 

 investigator says of the pseudo organisms : ' The whole 

 of the pseudo organisms resemble the true ones, even 

 under the most favourable conditions, only in the sense 

 of similar or like configuration and in similar or like 

 distribution of the aggregate parts. Thereby the 

 inorganic substance does not approach the peculiar 

 existence of the organic by a hair's breadth, any more 

 than does any other physiological model its living 

 original or let us say, for better exemplification, than 

 a model of a heart consisting of a rubber bag and the 

 necessary pumping apparatus would approach a living 

 heart whose beating only is represented by the model/ 3 



2. We are not justified in bringing animals and plants 

 into genetic connection. 



By animals we understand, as a preliminary, 

 organisms like Mammalia, Birds, Fishes, Worms; by 

 plants, Trees, Ferns, Mosses. All that falls under the 

 general category of ' life/ as we have already stated, em- 

 braces these beings. But a dog behaves in many vital 

 ways differently from a fruit tree for instance, in the 

 activity which he exhibits in seeking food or the other sex. 

 In it we observe vital expressions, which are similarly
