The  pharmaceutical  profession  has  been  discussing  of  late  the  pro- 
priety and  advisability  of  admitting  some  of  the  patented  synthetics 
to  the  U.  S.  Pharmacopoeia  at  the  next  (1900)  decennial  revision. 
Should  this  be  done,  it  is  likely  that  only  such  as  have  been  shown 
to  have  a  definite  chemical  structure,  together  with  valuable  medici- 
nal properties,  would  be  recognized  in  this  way,  and  the  work  rep- 
resented by  the  foregoing  list  may  prove  of  some  value  in  that

It  would  seem,  at  first  sight,  a  very  simple  proposition  to  deter-
