ON THE INFLUENCE OF DIFFERENT RATIOS OF LIME. 367 



favorable solution was due to the early removal of the organic 

 foodstores of the cotyledons. The weights and measurements 

 are shown in the following table :

It can be inferred from this, that a good development of 

 soy-beans is only secured, when the amount of lime exceeds 

 that of magnesia from two to three fold, and that a diminished 

 development becomes at once evident when the amount of lime 

 sinks to an equal with the amount of magnesia. 



V. Culture of Shoots of Onion-plants in the 

 Presence of all Mineral Nutrients. 



Shoots of onions were, on March 29th, put in the solutions 

 mentioned in III., and IV. 



How the different ratios of lime and magnesia gradually 

 influenced the development of new branches is seen from the 

 following table, in which only the number of the still living 

 branches is given.
