28 PLANT DISEASE 



the carbon of the plant is due to the presence 

 of chlorophyll in said plant, while I have 

 shown in the previous chapter that the 

 presence of chlorophyll is dependent upon the 

 presence of iron in the soil, from which it is 

 evident that the carbon of the plant, with its 

 products, is governed by the iron. 



We know that carbon and its products in 

 animal life are supplied in the food, therefore 

 it is imperative for plant life to have sufficient 

 iron. 



I have also shown that chlorosis of plants 

 is a most formidable disease, and it is clear 

 that there must be a large number of animals 

 living entirely or partly on this chlorotic 

 vegetable food, from which it follows that a 

 large portion of animal life must be more or 

 less anaemic through eating this chlorotic food. 



It is well known that innumerable diseases in 

 animal life are accompanied by anaemia, and 

 it seems evident that the eating of such 

 chlorotic food will produce the anaemic state 

 of the blood which is always found in con- 

 nexion with the development of certain dis- 

 eases, and which, I contend, precedes that 

 development. Proof to the contrary, at
