highly  pleased  with  it.  I  furnished  Dr.  Beard  with  numerous  copies 
of  it  at  his  request.* 
This  formula  was  published  in  the  "Druggists'  Circular"  for  October^ 
1874,  page  179.  I  can  say,  without  exaggeration,  that  I  have  made'  up 
barrels  of  the  emulsion,  although  the  formula  has  never  been  kept  a 
secret,  but  copies  have  been  furnished  to  all  who  requested  them. 
I  think  the  proportion  of  oil  of  bitter  almonds  used  by  Mr.  McEl- 
henie  is  too  large  to  be  safe  in  all  cases.  Perhaps  I  am  mistaken  in 
this,  however.  I  always  keep  a  quantity  of  the  glyconin  on  hand 
made  up.  The  proportions  are  four  parts,  by  measure,  of  the  yolks  to 
five  of  glycerin.

MISTURA  GLYCYRRHIZ^  COMPOSITA. 
BY  WALTER  E.  BIBBY,  PH.  G, 
For  the  consideration  of  the  readers  of  the  Journal,  I  desire  to  pre- 
sent the  following  suggestions  in  regard  to  the  preparation  of  mistura 
glycyrrhizae  composita.  In  place  of  the  usual  method,  which  consists 
in  rubbing  together  with  water,  licorice,  sugar  and  gum  arable,  I  pro- 
pose using  the  officinal  simple  syrup  and  mucilage  of  gum  arable  and 
a  solution  of  the  extract  of  licorice  (made  by  dissolving  the  extract  ins 
water),  of  such  a  strength  that  f^ii  shall  represent  §i  of  the  extract. 
The  formula  is  as  follows  : 
Take  of  Solution  of  extract  of  licorice,  .  .  .  f^i 
Syrup,       .......  f^v 
Mucilage  of  gum  arable,       ....  f^xi 
Water,  a  sufficient  quantity  to  make       .  .  .  f^xiiss 
Camphorated  tincture  of  opium,         .  .  .  .  f^ii 
Wine  of  antimony,  .....  f^i 
Spirit  of  nitrous  ether,  ....  f^ss 
Mix. 
I  am  not  aware  that  the  process  I  have  described  has  been  used  be- 
*  It  is  due  to  Mr.  McElhenie  to  state  that,  under  date  of  June  21st,  he  commu- 
nicated to  us  a  letter  from  Mr.  L.  M.  Royce,  correcting  the  statements  regarding  the 
origin  of  the  formula,  and  requested  us  to  make  the  necessary  alterations  in  the 
paper  published  in  our  last  number,  but  the  letter  arrived  too  late  for  this  purpose.
