removed  by  repeated  agitation  with  fresh  portions  of  ether.  In  one 
case,  treatment  like  the  extract  of  stramonium  was  found  necessary  in 
order  to  obtain  a  liquid  free  from  turbidity. 
Fluid  extract  of  veratrum  viride  was  acidulated,1  evaporated  to  a 
syrupy  consistence,  diluted  with  water,  and  filtered. 
This  table  shows  the  number  of  cc.  of  the  test  solution  used  to  pre- 
cipitate the  alkaloids  from  100  cc.  of  the  various  fluid  extracts,  the 
percentage  amount  of  alkaloids  in  each  sample,  and  the  specific  gravity 
of  the  several  fluid  extracts  examined  :
