In  our  opinion  a  far  worthier  resolution  was  the  one  offered  by 
Dean  La  Wall,  of  Philadelphia,  and  also  adopted : 
"Resolved,  that  the  members  of  the  Pennsylvania  Pharmaceuti- 
cal Association  emphatically  affirm  that  alcohol  is  a  necessary  solvent 
and  preservative  in  the  making  of  many  valuable  medicinal  prepara- 
tions, but  we  disapprove  the  illegal  dispensing  by  pharmacists  of 
alcoholic  liquors  or  liquids,  suitable  for  beverage  purposes,  and 
unanimously  recommend  the  expulsion  of  any  member  convicted  of 
such  practice." 
The  Pennsylvania  Pharmaceutical  Association  is  to  be  con- 
gratulated upon  its  adoption  of  the  latter  resolution,  but  is  amenable 
to  criticism  for  its  unwarranted  adoption  of  the  other  resolution, 
which,  in  correctness,  should  never  have  been  offered  in  session.

In  controlling  this  method  I  obtained  from  2.5  g.  licorice  0.240, 
0.249,  0.256,  0.257  g.  of  ammonium  glycyrrhizinate,  i.  e.,  9.44-10.08 
per  cent. 
The  losses  determined  on  5  g.  licorice  amounted  to  0.91-1.32  per 
cent.  They  are  thus  less  than  in  the  majority  of  similar  determina- 
tions. The  high  value  for  ammonium  glycyrrhizinate,  as  well  as  the 
slight  losses  show  that  the  method  is  a  practical  one.  The  favorable 
result  is  to  be  ascribed  to  the  use  of  ice  water,  and  to  the  low  tem- 
perature maintained  throughout.  The  detailed  procedure  is  not 
practicable  since  the  awkward  arrangement  of  freezing  gives  no 
better  results  than  allowing  to  stand  in  ice.
