FIG. 5 



The value of the auximones in promoting healthy growth is strikingly 

 illustrated above. Each of the treated plants (Primula malacoides] 

 received the water extract of ribth of an ounce of humogen, but 

 otherwise the treatment was identical. The increase of growth, 

 flowering, and of root development in the treated plant (on the 

 right) is very evident, but typical.
