by dividing the total elongation "by the corresponding 



nxunber of seedlings. The 21 hourlj'- rates are averaged 

 for each test and each late is expressed in terms of the 

 average of its own test. 



Inspection of 1hese sample data brings out 

 several points genarally aHP arent throughout 'tlie entire 

 mass of data for all six types and for all tempa: atures 

 tested. In the first place, no relation is discovered 

 between the solution composition (indicated by the solution 

 symbol in each case) and the number of soeds ■ftiat germin- 

 ated. The percentege of germination was not evidently 

 influenced by the salt proportions. "For the first test, th^ 

 number of seedlings obtained from 25 seeds ranged from 14 t o 

 24, for the second test this range is from 16 to '^4, and the 

 table shows very little agreement between the numbers of 

 seedlings obtained with the same solution in the two like 

 tests. This state of affairs holds for all the series in 

 about the same way, so that it became apparent tlB t the 

 germination percentage could not be considered .on th e bas is 

 of this study, as influenced ly the salt proportionE . It is 

 also true that this percentage was not apperently influenced 

 by the temperature. (Of course, germination was more rapid 

 with some temperatures than v;ith others; reference is here 

 made merely to the number of seeds that had
