Experiment A. 



Uniform seeds were soaked for 1 day in aq. destil. and were left to germinate 

 on germinating iilocks of plaster in darkness for 6 daj's (Okt. 13th to 19th 1908). 

 After these 6 days the radicles were 6 to 7 ctms. long. The seedlings were divided 

 as uniformly as possibly in 6 portions, each containing 44 plants. The heaviest 

 and the lightest portions were immediately crushed for analyses; the other portions 

 were allowed to remain for 2 days in a nutrient saline solution [the same as used 

 for the above mentioned experiments on lupines] partly with, partly without ether, 

 as indicated in the table; after this exposure they were crushed for analyses. For 

 the exposure tin-pails of 19 liters' capacity were used of which the covers were 

 fastened with plaster to prevent the vapours of ether escaping during the two days 

 of exposure. The temp, varied between 13° and 15°. The weights of the different 

 portions before the exposure are cited to demonstrate the uniformity of the material :

The total amount of Nitrogen is calculated by adding the amount of A^ of the 

 amides and that of N of the proteids. "Amides" indicates as usual the substances 

 of the alcoholic extract non-precipitated by tannic-acid while the rest is indicated 

 as proteids.
