unpleasant.  Like  the  mixtures  mentioned  before  the  addition  of 
water  renders  it  opaque. 
For  the  administration  of  the  tincture  and  fluid  extract  of  Canna- 
bis Indica,  malt  extract  answers  very  well ;  with  these  preparations 
the  best  result  is  obtained  with  the  following  proportions  : 
Tincturae  Cannabis  Indicae,  ^ss 
Extracti  Malti,  
Syrupi  Pruni  Virginianse,  ^ss 
With  Copaiva  it  is  necessary  to  proceed  much  the  same  as  in 
making  an  ordinary  emulsion,  starting  with  a  small  portion  of  the 
extract  of  malt  in  a  mortar  and  adding  with  trituration  alternately 
portions  of  copaiva,  malt  and  syrup.  The  mixture  retains  about  the 
color  of  the  malt,  forms  two  layers  on  standing,  but  is  easily  restored 
by  agitation. 
With  other  resinous  tinctures  and  fluid  extracts  the  results  have 
been  similar  to  those  described,  the  ones  selected  for  mention  being 
those  we  are  called  upon  most  frequently  to  dispense — and  are  also 
typical  resinous  substances.  Extract  of  malt  as  prepared  by  the 
official  process,  or  as  found  in  the  market  prepared  by  the  various 
manufacturers,  is  in  itself  too  thick  to  dispense  as  a  vehicle,  hence  it 
is  necessary  to  use  a  diluent  of  some  kind.  I  have  selected  the 
syrup  of  wild  cherry  for  the  purpose,  because  of  its  agreeable  taste 
and  slight  odor  of  hydrocyanic  acid.  With  extract  of  malt  made 
according  to  the  direction  of  the  Pharmacopoeia,  results  were 
obtained  identical  with  those  from  the  commercial  extracts ;  about 
the  only  difference  noticed  was  in  the  color  of  the  mixtures,  some 
of  the  commercial  extracts  being  of  a  darker  color. 
In  summing  up  the  result  of  my  work  in  this  direction  it  may  be 
said  that  in  extract  of  malt  we  have  a  ready,  inexpensive  and 
equally  good  substitute  for  Acacia  in  suspending  and  masking  the 
taste  of  disagreeable,  resinous  and  other  insoluble  substances, 
wherever  its  presence  in  small  quantity  is  not  found  to  interfere 
with  the  therapeutic  action  of  the  substance  prescribed.
