Summary. 



It is seen from these two experiments that for mycelium 

 fungi asparagine is a superior source of nitrogen, even far superior 

 to such a closely related compound as ammonium succinate. 

 Protein-production must then be much more easily possible from 

 the former than from the latter, i.e., the way from asparagine to 

 proteid is much shorter than that from ammonium succinate al- 

 though this is so closely related to asparagine. This conclusion 

 holds good also for phaenogams as shown above.
