ABSTRACT  OF  REPORT  PRESENTED  BY  COMMITTEE 
OX  ADULTERATIONS  AND  DETERIORATIONS  TO 
THE    PENNSYLVANIA    PHARMA  CEUTICAL 
ASSOCIATION. 
A  number  of  students  in  the  Chemical  Laboratory  of  the  Philadel- 
delphia  College  of  Pharmacy  contributed  their  time  to  obtain  some 
of  the  following  results  : — 
Mr.  Wm.  Handler  examined  six  samples  of  Simple  Syrup,  five  of 
which  were  found  close  to  the  officinal  requirements  and  one  was 
decidedly  inferior,  containing  only  forty  per  cent,  of  sugar. 
Mr.  Charles  A.  Schwacke  assayed  light  samples  of  Household 
Ammonia.  This  commercial  article  contained  from  3.72  to  10  per 
cent,  of  ammonia — XH3.    Two  of  the  samples  contained  borax. 
Mr.  Harry  S.  Wood  determined  the  strength  of  Glacial  Acetic  Acid, 
and  found  two  qualities  in  the  market  under  that  name,  one  contain- 
ing about  80  and  the  other  99  to  100  per  cent,  of  the  absolute  acid. 
The  latter  strength  can  always  be  gotten,  generally  with  the  percent- 
age on  the  label,  if  the  pharmacist  is  willing  to  pay  the  price.  The 
absolute  acid  is  easily  recognized  by  its  power  to  dissolve  an  equal 
volume  of  oil  of  lemon. 
Mr.  Charles  E.  MeCloskey  found  powdered  Belladonna  Boot  from 
different  wholesale  druggists  to  yield  from  0.2  to  0.4  per  cent.,  and 
the  Leaves  0.04  to  0.24  per  cent,  of  alkaloid. 
Mr.  A.  G.  Hostetter,  noticing  the  statement  frequently  made  that 
Potassium  Tartrate  is  often  impure  or  adultrated,  found  all  the 
samples  from  the  manufacturers  in  this  State  to  be  very  good,  con- 
taining only  traces  of  calcium  salts,  sulphuric,  hydrochloric  and 
carbonic  acids. 
Mr.  G.  M.  Grosse  found  Reduced  Iron  to  be  of  poor  quality,  one 
sample  only  answering  to  the  requirements  of  the  Pharmacopoeia.  They 
ranged  from  18.43  to  88.40  per  cent.  The  highest  being  of  German 
and  the  lowest  of  French  manufacture.  Those  of  American  make, 
being  obtained  from  stock  bottles  of  retail  pharmacists,  had.  no
