AmiZZ'im&Tm'}   Revision  of  the  U.  S.  Pharmacopoeia.  21 
the  syrup  which  is  not  directed  to  be  warmed  previously,  otherwise 
the  process  is  identical  with  that  of  the  Pharmacopoeia  of  1 870. 
Syrup  of  Hypophosphites  now  contains  a  small  amount  of  hypo- 
phosphorous  acid  in  place  of  the  citric  acid  of  the  1880  edition. 
The  quantity  of  sugar  directed  should  be  increased  to  600  gm.  In 
Syrup  of  Hypophosphites  with  Iron,  ferrous  lactate  is  retained,  but 
is  directed  to  be  dissolved  by  aid  of  potassium  citrate ;  ferric  hypo- 
phosphite  should  have  been  directed,  making  all  the  metallic  salts 
used  hypophosphites. 
The  addition  of  acetic  acid  and  glycerin  to  Syrup  of  Ipecac  is  a 
decided  improvement. 
It  is  a  question  if  in  the  new  official  formula  for  Syrup  of  Lactu- 
carium  the  valuable  portion  is  not  precipitated  by  the  water,  and 
allowed  to  remain  with  the  calcium  phosphate  on  the  filter  ?  With 
the  present  official  tincture  of  lactucarium  a  syrup,  yielding  but  a 
small  amount  of  precipitate  on  standing,  can  be  made  by  the  follow- 
ing formula:  tincture  of  lactucarium  100  cc,  glycerin  100  cc,  syrup 
800  cc,  mix  the  tincture  with  the  glycerin  and  add  the  syrup  to  the 
mixture. 
In  Syrup  of  Wild  Cherry  the  glycerin  is  greatly  increased,  and  is 
now  part  of  the  menstruum  and  not  added  to  the  percolate.  We 
cannot  approve  this  formula,  as  the  resulting  syrup  is  more  remark- 
able for  astringency  than  flavor. 
Syrup  of  Rhubarb  is  a  decided  improvement  over  the  formula  of 
1870,  and  yields  a  more  stable  preparation. 
In  Compound  Syrup  of  Sarsaparilla  the  suggestion  of  Oldberg  to 
omit  both  the  guaiac  wood  and  pale  rose  has  been  adopted,  and  oils 
of  sassafras  and  gaultheria  have  again  taken  the  place  of  their  respec- 
tive drugs  directed  in  the  Pharmacopoeia  of  1880  The  use  of  fluid 
extracts  of  sarsaparilla,  glycyrrhiza  and  senna  in  the  preparation  of 
this  syrup  is  another  innovation. 
For  preparing  Syrup  of  Senna,  Alexandria  senna  only  is  rightly 
directed  to  be  used.  In  the  direction  for  this  preparation  we  are 
instructed  to  prepare  600  cc.  of  infusion.  "  Strain  this,  and,  when  it 
is  cold,  mix  it  with  the  alcohol  (150  cc.)  in  which  the  oil  of  coriander 
(5  cc.)  has  previously  been  dissolved.  Set  it  aside  until  the  pre- 
cipitate has  subsided,  then  pour  off  the  clear  liquid,  filter  the 
remainder,  and  pass  enough  water  through  the  filter  to  obtain  5  50  cc." 
It  is  to  be  noted  that  755  cc.  of  liquid  is  to  be  filtered,  and  the  fil-
