Germinating' seeds liave considerable anti-scorbutic value 

 even before the appearance of any g-reen leaves. They have 

 also growth-promoting- properties. In this case the vitamines 

 seem to have been produced as the result of enzyme activity 

 in the g-erminating seed. 



Yitamines may rlius be produced either in connection 

 with photosynthesis or in connection witJi tlie deposition of 

 reserves. In the latter case, the anti-scorbutic vitamine is 

 found in the living turgid cells of underground storage 

 organs or of succulent fruits, while the anti-neuritic vitamine 

 is found in the much drier dormant cells of the resting embryo. 

 Yeast is known to be rich in the anti-neuritic vitamine. but 

 other fungi have not vet been tested.
