15 
per  cent,  of  lemon  oil,  adding  another  to  the  already  growing  list 
of  standards  for  flavoring  extracts  which  are  eagerly  seized  upon 
as  authoritative  by  manufacturers,,  when,  as  in  this  case,  they  are 
below  the  standards  generally  recognized  by  the  food  laws. 
Formula  97  is  for  Compound  Powder  of  Acacia,  to  be  used  as  an 
emulsifying  agent.  It  contains  5  per  cent,  of  boracic  acid,  and  in 
the  light  of  the  prohibitory  legislation  regarding  boron  compounds 
in  this  country,  its  presence  would  seem  to  be  objectionable,  at  least 
on  this  side  of  the  border. 
No.  105  calls  for  powder  for  chalk  mixture.  It  differs  essentially 
in  character  from  the  powder  used  officially  in  this  country  in  that 
it  contains  tragacanth  instead  of  acacia. 
No.  120,  for  Syrup  of  Tar,  prescribes  the  use  of  fifteen  times 
as  much  tar  as  is  present  in  the  U.  S.  P.  syrup  of  tar,  although  the 
directions  for  its  preparation  are  practically  the  same.  It  is  ques- 
tionable whether  this  increased  amount  of  tar  would  result  in  pro- 
ducing a  preparation  of  any  greater  efficiency,  owing  to  the  com- 
parative slight  solubility  of  that  constituent  in  the  boiling  water. 
Formula  No.  128,  for  Tincture  of  Fresh  Sweet  Orange  Peel,  is 
half  the  strength  of  the  U.  S.  P.  8th  Rev.  formula. 
No.  140,  for  Diachylon  Ointment,  consists  of  equal  parts  of 
lead  plaster  and  soft  paraffin,  flavored  with  oil  of  bergamot,  and 
differs  materially  from  the  U.  S.  P.  preparation,  which  is  made 
from  lead  plaster  and  olive  oil,  flavored  with  oil  of  lavender. 
It  is  unfortunate  that  errors  and  inconsistencies  of  this  kind 
should  find  their  way  into  an  authoritative  work  of  this  character, 
which,  in  some  sections  of  our  country,  at  least,  is  of  importance, 
but  slightly  inferior  to  our  own  U.  S.  P.  and  N.  F.,  and  it  is  to  be 
hoped  that  any  future  edition  will  contain  corrections  of  many  of 
these  formulas.
