Similar  preparations  are  Uropherin  S  and  Uropherin  B,  the 
analyses  of  which  follow.  We  think  chemists  will  agree  with  us  in 
considering  such  preparations  as  mixtures.

The  remaining  preparations  which  we  will  bring  to  your  attention 
are  of  the  nature  of  "  frauds"  of  variable  dimensions,  and  indicate 
that  charlatanism  in  medicine  is  not  entirely  confined  to  the  reme- 
dies sold  to  the  general  public.  They  are  offered  for  sale  to  the 
medical  profession  only,  purport  to  be  of  definite  composition — a 
formula  being  given  in  some  cases — and  are  provided  with  a  trade- 
mark name  suggestive  of  either  pathologic  conditions  or  chemical 
components,  after  the  manner  of  synthetic  remedies.  Acetanilid 
seems  to  be  a  favorite  ingredient,  appearing  in  preparations  in- 
tended for  topical  use,  as  well  as  in  those  recommended  for  internal 
administration  as  antipyretics. 
Phenalgin  is  a  preparation  which  is  described  on  the  label  as 
"  phospho-ammonio-phenylacetamide."  It  is  the  ordinary  type  of 
"  headache  powder,"  as  will  be  seen  by  the  analysis  :
