When I speak of the cell I generally mean the largest 

 cells and the social cells which have the habit of building 

 themselves into social colonies, like plants and animals. 

 The different sizes and species of cells are simply unlim- 

 ited. These smaller cells called germs and bacteria seem 

 to make food for the larger, in the same manner as ani- 

 mals feed one upon the other. It is evident that un- 

 counted numbers of ultra microscopic species of germs 

 exist that never will be seen. Those large cells that are 

 well known, however, such as build for themselves cov- 

 erings of a pearly, horny or flinty material, and still retain 

 their separate single existence, as well as those that or- 

 ganize themselves into social colonies, like plants and 

 animals, certainly exhibit all the characters of an intelli- 

 gent being; they discharge every function of the higher 

 animals. There is no doubt in my mind that every cell 

 is composed of still smaller cells, and that the size of 

 every cell depends on the number and organization of the 

 primordial beings which together make up the cell. Every 

 cell is a crowd of thousands or more individuals, each one 

 having this special work to do just as the organs of an 

 individual have their special work to do in different places 

 of the body. 



When the cell multiplies by division, there is simply 

 an even division of the individuals, each half receiving his 

 share of the beings and equipment possessed by the cell. 

 Who is this being in the cell who takes charge of and 

 directs the work of equal division of the cell? We see 

 him do the work and we call him centrosome. Intelli- 

 gence is clearly shown by this individual, who looks after 

 this important work. A great number of the cells who 

 build plants and animals live a single and separate life 

 several months before they begin building the plants and 

 animals. Such is the case with several sea and water
