Tannate  of  Quinia. — M.'D.  Smedt  (Jour.  d'Anvers)  states 
that  the  usual  method  of  obtaining  this  salt  is  to  decompose  a 
solution  of  acetate  of  quinia  with  a  solution  of  tannin.  But  it 
is  found  that  a  large  excess  of  tannin  is  required,  which  M. 
Smedt  considers  to  be  due  to  the  influence  of  the  acetic  acid 
thrown  out  of  combination.  To  prevent  this  interference,  he 
proposes  to  carefully  saturate  the  tannin  with  ammonia,  so  that 
the  reaction  shall  be  between  tannate  of  ammonia  and  acetate 
of  quinine,  which  prevents  all  difficulty.  The  precipitated  tan- 
nate is  washed  with  water  and  dried. 
Tannate  of  quinia  is  employed  in  infantile  cases,  where  the 
sulphate  has  a  harsh  action  on  the  stomach  and  bowels. — Jour, 
de  Pharm.,  Aout,  1863.
