the  root  by  boiling  it  with  milk  of  lime  and  adding  muriatic  acid 
to  the  decoction.  The  precipitate  is  boiled  with  a  solution  of 
baryta,  the  filtrate  decomposed  by  muriatic  acid,  the  precipitate 
dissolved  in  alcohol,  decolorized  with  animal  charcoal,  and  the 
alcohol  partly  recovered  by  distillation,  when  kinovic  acid  sepa- 
rates as  a  crystalline  powder. — Annal.  d.  Ch.  und  Ph.  cxliv,  5. 
Gentian  for  Bougies.  Prof.  F.  Winkler,  of  Rostock,  recom- 
mends gentian  as  a  dilatatory  of  the  vagina  and  uterus,  and  for 
various  other  purposes.  It  is  cheap,  may  be  obtained  of  any  re- 
quired thickness,  does  not  swell  excessively,  and  does  not  acquire 
a  disagreeable  odor  if  impregnated  with  mucus  and  pus. —

Charta  Sinapinata  of  Rigollot.  Sized  paper  is  covered  with  a 
solution  of  caoutchouc  in  bisulphide  of  carbon  or  with  a  thin  so- 
lution of  resin.  It  is  then  covered  with  fine,  well-dried  powder 
of  black  mustard  deprived  of  its  oil,  and  passed  between  two 
cylinders.  Rigollot's  paper  has  a  stratum  of  mustard  *7  milli- 
metres in  thickness,  which  adheres  well  and  does  not  peel  off  on 
bending. — Pliarm.  Central  Halle,  1867.    No.  38.

.Pure  Carbonate  of  Lime  is  obtained  by  Dr.  Grseger  by  slak- 
ing burned  lime  and  digesting  it  with  a  solution  of  nitrate  of 
ammonia,  leaving  the  lime  somewhat  in  excess.  The  liquid  con- 
tains only  nitrate  of  lime  and  free  ammonia,  none  of  the  impuri- 
ties found  in  lime  being  dissolved.  Carbonic  acid  gas,  if  passed 
through  the  solution,  precipitates  pure  carbonate  of  lime  as  a. 
dense  crystalline  powder.  It  is  advisable  to  add  to  the  liquid  a 
little  carbonate  of  ammonia  before  filtering  it.  The  filtrate  is 
neutralized  with  nitric  acid,  if  necessary,  and  serves  again  for 
dissolving  burned  lime.  The  only  expense  occurs  from  the  gen- 
eration of  carbonic  acid. — N.  Jahrb.f.  Ph.  1858,  March,  158.
