The ph^-sicü-chemical coiistants determiiied for these series ap- 

 pear in Table 4-5. For the fertility series they are compared with 

 the slope of the regression line calctilated by the above equation for 



TABLE 4 



A. Constants for juice of pears producing various numbers of seeds 



B. Constants for juice of apples producing various numbers of seeds 



TABLE 5 



Constants for juice of pears of various weights in classes of lo-gram ränge 



6 This value of A is obviously erroneous, but the slip was not observed until 

 it was too late to make another determination. It aft'ects the mean molecular 

 weight and the osmotic pressure.
