RESUME  OF  THE  REPORT  OF  THE  COMMITTEE  ON 
ADULTERATIONS  TO  THE  OHIO  STATE  PHARMA- 
CEUTICAL ASSOCIATION. 
By  Prof.  B.  S.  Young  and  J.  D.  l,ism,  M.D. 
Acida. — Samples  of  nearly  all  common  acids  were  examined  and 
were  found  to  fulfill  the  official  requirements  of  strength  and  purity. 
Acidum  Boricum. — The  products  of  three  prominent  manufac- 
turers were  examined.  They  conformed  in  every  particular  to  the 
demands  of  the  Pharmacopoeia. 
Bismuthi  Subcarbonas  contained  traces  of  chloride,  alkali  or  alka- 
line earths  and  arsenic. 
Cinchona. — The  amount  of  alkaloids  in  the  five  samples  assayed 
ranged  from  1*5  per  cent,  to  5  per  cent.,  with  an  average  of  3  4  per 
cent.  The  lot  that  showed  5  per  cent,  of  total  alkaloids  contained 
1  "6  per  cent,  of  quinine. 
Glyceriniun,  of  which  fourteen  samples,  representing  all  the  lead- 
ing brands,  were  subjected  to  examination,  was  found  to  be  satisfac- 
torily pure.    The  absence  of  arsenic  was  particularly  established. 
Iodoformum. — One  sample  of  the  crystals  and  two  of  the  powdered 
article  were  tested.  A  sample  of  the  latter  yielded  0-08  per  cent, 
of  fixed  impurities.  The  other  products  were  entirely  dissipated  by 
heat.  Water,  shaken  with  the  substances,  remained  tasteless,  color- 
less and  neutral,  but  contained  iodide,  as  was  shown  by  silver  nitrate. 
Jalapa. — 11*5  per  cent.,  12-6  per  cent  and  12  5  per  cent,  of  resin 
was  obtained  from  the  three  different  lots  estimated.  One  and  a 
half  per  cent,  of  the  yield  from  the  first  quality  was  soluble  in  ether* 
The  resin  from  the  other  two  samples  was  entirely  soluble. 
Olenm  Lini. — A  sample  of  this  was  found  to  be  viscid,  opaque,  of 
fishy  odor  and  neutral  to  litmus.  On  standing  it  threw  down  a 
white  precipitate.  Further  examination  showed  it  to  be  adulterated 
with  paraffin  and  cottonseed  oil. 
Opium. — Assays  by  the  U.  S.  P.  method  showed  an  average  of 
1 2- 1 8  per  cent,  of  morphine  in  the  four  samples  treated.  The  results 
obtained  ranged  from  8-9  per  cent,  to  15  6  per  cent. 
Paraldehydum  was  found  to  be  of  very  strongly  acid  reaction. 
Sulphuric  and  hydrochloric  acids  were  not  detected  in  either  of  the 
three  products.  Mixtures  of  8  c.c.  of  each  sample  in  an  equal  volume 
of  alcohol,  with  phenolphthalein  as  an  indicator  required  respect-
