To  hide  the  bitter  taste  of  some  medicines,  like  quinia,  colocynth, 
aloes,  quassia,  &c,  L' Union  pharmaceutique,  1872,  Dec,  proposes 
to  keep  some  liquorice  in  the  mouth  after  taking  such  substances, 
when  the  bitter  taste  will  instantly  disappear.*  Liquorice  merely 
masks,  it  does  not  destroy  the  bitter  taste ;  its  action  is  analogous  to 
that  of  bitter  almonds  upon  musk,  and  of  anise  upon  valerian.  When 
musk  is  triturated  with  some  distilled  bitter  almond  water  the  musk 
odor  disappears,  but  gradually  reappears  as  the  oil  of  bitter  almonds 
evaporates. 
*  A  new  falsification  of  ammoniac  is  reported  by  Ch.  Meniere,  who 
observed  globular  pieces  of  translucent  quartz  varying  in  color  be- 
tween white,  yellow,  orange  and  reddish,  imbedded  in  the  gum  resin, 
so  as  to  give  it  the  appearance  of  a  handsome  article,  and  calculated 
to  deceive  unless  closely  inspected.— Ibid.,  p.  355.
