ating  NH3  as  Am  it  is  AmHAc,  that  is  the  basic  radicle  NH^  or  AmH 
united  with  the  acid  radicle  Ac.  Representing  emetine  by  Em  we 
have  for  emetiiim  acetate  Em-j-HAc  or  EmHAc  and  emetiuni  hydrate 
Em-[-OH^=EmH(OH).  Writing  quinine,  quinidine  and  cinchonine 
Qn,  Qd  and  Cn  we  have  for  the  chlorides  QnHCl,  etc.,  for  the  sul- 
phates (QnH)2  SOjt,  etc.,  and  for  the  phosphates  (QnH)2  HPO^,  etc. 
Returning  now  to  syrup  of  ipecac,  we  have  the  formula  for  4  pints, 
as  follows  : 
Take  of  . 
Ipecac,  coarsely  bruised,       .         .         .         4r}  troy  ounces. 
Sugar,  granulated,  .  .         .   ■      .     48    '*  " 
Calcium  carbonate,     .         .         .         .  "  ounce. 
Ammonia  water,  .         .  .         .         .4  fluid  " 
Alcohol,  1      ^^^j^  sufficient. 
Water, 
Mix  alcohol  and  water  in  the  proportion  of  one  volume  of  the  first 
and  seven  of  the  second,  and  pour  25  fluid  ounces  of  the  mixture 
together  with  the  ammonia  water  upon  the  ipecac  contained  in  a  wide- 
mouthed  bottle.  Macerate  the  mixture  for  3  or  4  days,  shaking  it  up 
occasionally;  then  decant  16  fluid  ounces  of  the  liquid.  On  the  resi- 
due pour  16  fluid  ounces  of  the  menstruum,  and  after  3  or  4  days^ 
maceration  decant  16  fluid  ounces  as  before.  Mix  the  two  decantates, 
add  the  calcium  carbonate,  agitate  and  filter.  Pour  the  filtrate  on  the 
sugar  contained  in  a  proper  vessel,  stir  until  most  of  the  sugar  has 
dissolved  and  decant  about  3  pints  of  the  syrup.  Heat  the  remainder 
until  solution  is  affected,  then  mix  the  whole  and  strain. 
The  compound  syrup  of  ipecac,  or  substitute  for  Dover's  powder,  is 
extensively  in  use.  But  it  is  not  properly  prepared,  being  fermenta- 
ble and  otherwise  unsatisfactory.  A  permanent  and  elegant  syrup 
containing  J  a  grain  each  of  opium  and  ipecac  in  the  fluidram  is  pre- 
pared by  the  following  ready  formula  : 
Take  of 
Deodorised  tincture  opium,       .         .         .         8  fluidrams.

Gold  Cream  easily  becomes  rancid.  The  addition  of  salicylic  acid 
has  been  found  an  excellent  preventive  against  this  tendency,  which 
usefulness  is  enhanced  by  its  healing  qualities.
