"  Pharmacopoeia."  The  sugar  is  then  dissolved  by  percolation  in  the 
menstruum  thus  obtained  ;  the  tartrate  of  antimony  and  potassium  dis- 
solved in  a  small  quantity  of  boiling  water  and  added  to  the  syrup  ; 
lastly,  the  quantity  required  is  made  up  by  the  addition  of  pure  cold 
water. 
If  the  above  general  process  is  strictly  adhered  to,  nearly  all  syrups 
(official  and  officinal)  can  be  made  by  it.  It  will  also  be  seen,  on  the 
first  application  of  this  process,  that  it  is  the  cleanest^  handsomest  and  most 
economical  of  all  the  processes  thus  far  placed  before  the  profession^  and  it 
adds  largely  to  the  filling  of  a  vacancy  in  the  art  of  pharmacy  so  long 
admitted  to  be  an  impossibility.

SOME  SUGGESTIONS  TO  THE  NEXT  REVISION  OF  THE  "UNITED 
STATES  PHARMACOPCEIA." 
BY  H.  M.  WILDER. 
Jcidum  Phosphoricum  Dilutum. — One  of  the  formulas  ought  to  be 
omitted,  since,  however  therapeutically  they  may  be  identical,  pharma- 
ceutically  they  differ  in  their  behavior  to  tinct.  ferri  chloridi  [see  "  Pro- 
ceedings Am.  Pharm.  Assoc.,"  1874,  pp.  431  and  511). 
Syrupus  Krameria. — A  similar  objection  can  be  made,  since  the  syrup 
made  with  aqueous  extract  mixes  clear  with  water,  whilst  that  from  the 
fluid  extract  gives  a  turbid  mixture. 
Tinctura  Croci. — It  is  a  well-known  fact  that  most  of  the  elder  phy- 
sicians have  been  disagreeably  surprised  by  finding  that  saffron  has  been 
left  out  of  tinct.  cinchon.  comp.  (in  the  edition  1873),  which  it  for- 
merly was  a  constituent.  It  is  therefore  proposed  to  add  a  tincture  of 
saffron  to  the  list.  The  proportion  of  i  saffron,  6  alcohol,  2  water 
(that  is  I  to  8),  would  be  convenient;  or  perhaps  i  to  10  would  be 
better,  since  we  probably  by-and-bye  will  have  to  do  everything  on  the 
"/^«"  system.  When  needed,  add  to  each  fluidounce  of  tinct.  cinchon, 
comp.  (1873)  ^5  "linims  tincture  of  saffron  (=  3  grains).
