Assay  of  D?'ugs. 
(Am.  Jour.  Pharm. 
I     October,  1900. 
In  the  above  experiments,  the  maximum  growth  of  the  seedlings 
occurred  in  the  solution  containing  grain  alkaloid  in  50  c.c.  of  the 
alcoholic  solution,  and  death  in  the  solution  containing  4-  grain. 
The  succeeding  table  on  p.  479  gives  the  results  at  the  end  of  the 
second  twenty-four  hours. 
In  the  second  twenty-four  hours  we  notice  a  corresponding  in- 
crease in  growth,  as  was  noted  in  previous  experiments.
