Rud  and  ink  stains  can  be  removed  by  moistening  the  spots,  and 
rubbing  on  them  a  mixture  of  2  parts  cream  of  tartar  and  1  part  of 
oxalic  acid.  When  the  stain  disappears  it  is  washed  out  with  water. 
This  mixture  does  not  affect  the  fabric,  and  hence  is  preferable  to 
oxalic  acid  alone. — Rundschau. 
Paraldehyde  suppositories  can  be  made  by  fusing  paraldehyde  with

Liquor  Thioticus  s.  Sulphuratus. — Under  this  name  Dr.  Hager  uses 
a  solution  of  0*2  washed  sulphur  in  5  cc.  of  carbon  bisulphide,  to 
which  5  cc.  benzol  and  10  cc.  of  ether  are  added,  as  a  substitute  for 
sulphide  of  ammonium  or  sulphydric  acid.  The  benzol  and  ether 
are  added  to  make  the  liquid  lighter  than  water.  He  proceeds  as  fol- 
lows :  A  small  quantity  of  solution  of  caustic  soda  is  added  to  some 
of  the  test  liquid ;  the  substance  to  be  examined  is  then  added  and 
the  mixture  heated  to  boiling,  agitating  constantly.  To  test  for 
arsenic,  antimony  and  tin,  muriatic  acid  is  added  after  the  evaporation 
of  the  ether.  Liquor  thioticus  is  readily  prepared  and  free  from  the 
disagreeable  odor  of  sulphuretted  hydrogen. — Rundschau.
