Ammonium  Carbonate  like  the  U.S. P.  is  the  academic  statement 
rarely  if  ever  found  in  commerce. 
Cantharides  is  required  to  contain  0.8  per  cent,  of  Cantharidin. 
The  assay  process  has  been  improved  by  recrystallizing  the  product 
from  Acetone,  but  it  still  does  not  yield  a  colorless  and  pure  product. 
Sulphuric  Acid  is  94  to  98  per  cent.  H2SO4,  the  crude  91  per 
cent,  and  the  diluted  15.6  to  16.3  per  cent. 
Capsules  are  described  as  of  two  forms,  the  platter  or  cup-shaped 
made  of  wheat  flour  or  wheat  starch,  and  the  hollow  gelatin  capsule. 
Catechu  is  retained ;  no  Gambir  for  the  Germans. 
Cinchona  is  restricted  to  the  Bark  of  Cinchona  Suiccirubra 
Pavon. 
Quinine  Sulphate :  The  chemical  formula  is  given  as  containing 
8  molecules  of  water.  The  U.S. P.,  while  giving  the  formula  as 
7H2O,  in  the  text  allows  a  loss  in  drying,  "  indicating  not  more  than 
8  molecules  of  water." 
Cinnamon :  The  Ceylon  bark  replaces  the  Chinese  and  the  oil  ol 
Ceylon  Cinnamon  is  now  the  German  ofiicial  oil  of  cinnamon. 
Fluidextracts :  But  four  new  ones  have  been  added,  namely, 
cascara,  cinchona,  granatum  and  simaruba.  The  Cinchona  contains 
17  parts  of  Diluted  Hydrochloric  Acid  in  100  and  is  essentially  the 
formula  of  the  British  Pharmacopoeia. 
Sassafras  is  the  wood  of  the  root. 
Solution  of  Iron  Albuminate :  Fresh  hen's  egg  albumin  replaces 
the  dried  of  the  previous  edition.  The  variability  of  the  commer- 
cial dried  albumin  and  disagreeable  odor  possessed  by  many  sam- 
ples necessitated  this  change. 
Liquor  potassii  hydroxidi  and  Liquor  sodii  hydroxydi  are  both 
"  about  15  per  cent."  while  the  U.S. P.  are  only  about  5  per  cent. 
Magnesium  Carbonate :  Two  chemical  formulas  are  given  show- 
ing varying  mixtures  of  magnesium  carbonate  and  hydroxide,  the 
one  with  3  molecules  of  HoO  and  the  other  with  4.  The  U.S. P. 
gives  the  latter  formula  but  with  5  molecules  of  water.  Probably 
both  authorities  give  academic  formulas  that  do  not  describe  the 
trade  article. 
Opium  is  required  to  contain  "  not  less  than  T2  per  cent,  of 
morphine  after  drying  at  60°  C."  It  would  be  rather  difficult  to  dry 
a  substance  like  opium  uniformly  at  that  temperature. 
Powdered  Opium  is  required  to  contain  10  per  cent,  of  anhydrous 
morphine.  The  U.S. P.  standard  12  to  12.5  of  crystallized  morphine 
varies  but  slightly  from  the  international  agreement.
