ed to only 1.48 cc. The white beans decreased rapidly in vol- 

 ume, reaching the minimum, - 2,88 cc. in two and one half hours. 

 After this there was an increase but the volume did not equal 

 that at the beginning of the experiment until four and one half 

 hours later, or seven hours after the first reading. The in- 

 crease was very rapid towards the close of the experiment which 

 was continued for thirteen hours. 



While there is quite a similarity in the curves represent- 

 ing the volume change as determined by Nobbe and myself there 

 are the following differences; I find the maximum and minimum 

 points to be reached much sooner than Nobbe, This is probably 

 due to a higher temperature (22°C). After two and three fourths 

 hours my minimum is below the volume at' the beginning while the 

 corresponding low point in Nobbe' s experiment is reached after 

 four hours and remains a considerable above the original volume. 

 After four hours soaking I find a constant increase to the end 

 of the experiment. Nobbe finds an increase during the first 

 three hours of the corresponding period and then a slight 

 decrease. Nobbe finds in the beans a very rapid increase in the 

 first ten minutes and then a rapid decrease, reaching - 13 cc 

 in two hours and reaching the minimum after eight hours soak- 

 ing. There is shown a slight increase following -this lowest 

 point. I find no increase at first, but a decrease in volume 

 which reaches the minimum (- 5 cc ) in the first forty five
