CAUSE OF HEREDITY 295 



This shows the wonderful skill and intelligence of the 

 cells in building the smaller individuals like insects. You 

 will notice how the cells are able to change the form of 

 the insect as it becomes necessary to effect the results 

 desired. Sometimes he is this and again he is that, as 

 circumstances require. In the past ages their knowledge 

 and experience in life have taught them how to build all 

 these different structures and perform all these different 

 and difficult acts. Their memory of the past must neces- 

 sarily direct them in every act. Those actions and ex- 

 periences are their knowledge, that is to say, the cells that 

 occupy the insect and build these different forms, co- 

 operate in a social way and build these structures which 

 are adapted and required in order to be able to rob the 

 bee of its honey and convert it to their own use. 



The various constructions produced by the cells show 

 that they produce what they deem necessary and what 

 may be required for their perpetuation and the continu- 

 ance of life. They follow no fixed rule, but have an ideal 

 and purpose, which one also finds in the productions of 

 man. Can intelligent man equal the performance of this 

 cell colony called Sitaris? I think not. 



Mr. Binet has ventured so far as to show by their ac- 

 tions that they must be possessed of instinct, just as 

 animals are and makes the following statements : 



"We may reply upon this point, that there is not a 

 single ciliate Infusory that cannot be frightened and that 

 does not manifest its fear by a rapid flight through the 

 liquid of the preparation. 



"If a drop of acetic acid be introduced beneath the 

 glass slide in a preparation containing quantities of In- 

 fusoria, the latter will at once be seen to flee from all 

 directions like a flock of frightened sheep. 



"Memory, according to M. Romanes, first begins with
