The conclusions have been derived from many more experi- 
ments than are indicated by the above tables. Yet those. 
given represent the typical and normal results and also show 
the mode of experimentation. 
NaCl—Peas and beans will germinate in NaCl solutions 
of strengths as high as two per cent. In stronger solutions 
germination rarely occurs. A solution of two per cent or one 
per cent has a toxic influence and causes the seedlings soon to 
shrivel. A one-half per cent to a one-third per cent solution 
can be regarded as neutral, % ¢., a solution which neither: 
retards nor accelerates growth, or one which acts like ordi- 
nary atmospheric moisture. All solutions weaker than one- 
third per cent act as stimulants to the seedling and cause an
