Eate and Amount of Absorption in Alcohol. 



Experiments were conducted in which corn, peas, and lu- 

 pines were soaked in alcohol of the following per cents; Ab- 

 solute, 95 X, 75 X, 50 X, 30 X, 20 X, 10 X, and distilled 

 water. Tables 15 and 16 give the weights of the seeds in the 

 different per cents of alcohol at intervals of twenty four 

 hours. Tables 17, 18, and 19 give the per cent gain and the 

 mean per cent gain for corn, peas and lupines respectively. 

 Accompanying these tables are sets of curves, J and K repre- 

 senting the average per cent gain in corn and peas respectfully 

 Because of the lack of uniformity in the lupines I have thought 

 best to give curves L and M, representing the mean per cent 

 gain for experiments 1 and 2 and N represents the average per 

 cent gain of these experiments. 



The results show that corn, peas, and lupines may in- 

 crease in weight when soaked in absolute alcohol and that in 

 general, the lower the per cent of alcohol the greater the 

 amount of gain in a given time. The variations from this gen- 

 eral rule must find their explanation in the facts and con- 

 clusions given in the paragraph concerning the lupines, which 

 follows.
