alcohol  direct  shaking  out  with  this  solvent  does  not  work.  Best 
method  is  to  dilute  glycerin  solution  with  water  and  precipitate 
morphine  as  periodide  by  Wagner's  reagent.  From  the  periodide 
the  alkaloid  is  recovered  in  the  usual  way.  About  80  per  cent,  of 
morphine  is  recovered  by  this  method.    (See  p.  464). 
Some  Alkaloidal  Assays. 
By  H.  M.  Gordin. 
By  means  of  three  special  apparatus  alkaloidal  assays  can  be 
made  more  exact.  Instead  of  ammonia  fixed  alkali  or  alkaline  car- 
bonates can  be  used  to  set  alkaloids  free.  By  using  proper  immis- 
cible solvents  no  alkali  contaminates  alkaloids  except  traces  of 
ammonia  formed  by  action  of  alkali  upon  the  albuminous  matter  of 
drug.  Concentrations  of  ethereal  solutions  of  alkaloids  can  be  car- 
ried out  in  a  special  separating  funnel  and  thus  transferring  of  liquid 
from  vessel  to  vessel  avoided.  Exact  separation  of  immiscible 
solvents  is  accomplished  by  using  separating  funnel  with  two 
outlets.    (See  p.  458). 
Gelsemium. 
By  L.  E.  Sayre. 
A  further  study  of  the  fresh  and  dry  root  with  reference  to  the 
alkaloidal  content  in  the  two  conditions.  The  fresh  root  was  care- 
fully collected  and  a  portion  of  the  same  dried.  The  two  were 
analyzed,  or  assayed.  The  present  paper  is  a  sequel  to  the  one 
presented  to  the  Association  last  year,  and  touched  upon  the 
question  of  the  process  of  assay  of  gelsemium.

A  Method  for  the  Preparation  of  Solutions  of  the  Active 
Principle  of  the  Suprarenal  Gland. 
By  Charles  E.  Vanderkleed. 
The  author,  in  this  paper,  describes  a  method  for  preparing  a 
solution  of  the  active  principle  directly  from  the  suprarenal  gland.
