SUMMARY 



The work reported would seem to show that rice can not assimilate 

 colloidal iron. It is believed that the iron obtained from the dialyzed- 

 iron preparation was soluble iron. 



It is apparent that the toxicity of ordinary distilled water or ferric- 

 chlorid solutions for plant roots can not be overcome by supplying other 

 roots of the same plant with a balanced.solution. 



The toxicity of the ferric-chlorid solution was accompanied by the 

 penetration of iron into the root and transportation, to the leaves.
