result. 
These  results  seem  to  demonstrate  a  number  of  facts.  The

effect  of  the  acid  treatment  as  conducted  in  this  experiment  is  of  little 
practical  value,  the  only  benefit  derived  being  that  of  a  slight  accele- 
ration in  germination.  The  total  germination  is  not  found  to  be 
any  greater,  on  the  whole,  than  in  the  case  of  seeds  not  subjected
