Preservation  of  Vegetable  Powders. — Mr.  L.  Cre'teur  reports  on  the 
method  for  the  preservation  of  vegetable  powders,  proposed  by  Louis 
Corne'lis,  pharmacist  at  Diest,  and  which  consists  essentially  in  keep- 
ing the  powders  dry  by  means  of  burned  lime.  This  is  effected  by 
means  of  glass  bottles,  into  the  wide  mouths  of  which  hollow  pear- 
shaped  stoppers  are  fitted,  having  below  a  large  opening,  which  grad- 
ually becomes  smaller,  and  on  the  outside  a  thread-like  groove  for 
fastening  the  paper  and  linen.  The  cavity  of  the  stopper  is  filled  with 
pieces  of  burned  lime,  and  double  thicknesses  of  filtering  paper  and 
linen  are  tied  over  it,  after  which  the  stopper  is  inserted. f  The  au- 
thor has  had  powdered  rue,  preserved  in  this  manner,  in  his  posses- 
sion for  four  years,  during  which  time  it  preserved  its  color  and  odor 
perfectly. — Bull.  Soc.  Roy.  Phar.  de  Brux.,  1873,  November. 
*It  appears  to  us  that  this  syrup  is  intended  to  represent  principally  the 
sedative  properties  of  wild  cherry  bark,  and  that  for  this  reason,  evaporation 
of  any  portion  of  the  percolate  should  be  avoided.  If  an  uniform  and  fine  pow- 
der of  the  bark  is  used  and  its  percolation  is  properly  managed,  evaporation 
will  not  be  necessary. — Editor. 
t  This  is  an  improvement  of  M  ohr's  method  for  the  preservation  of  vegetable 
drugs,  which  are  kept  in  the  drawers  upon  a  perforated  tin  box  containing 
burned  lime. — Editor  Am.  Journ.  Phar.
