BARK  OF  CBDRELA  FEBRIFUGA.

nually  3,396,846  lbs.  of  cork  bark,  and  producing  about 
10,000,000  corks.  90,000,000  ready  made  corks  are  obtained 
from  the  neighboring  places  of  Nesac,  Bajonne,  and  Provence. 
The  cork  trade  of  Bordeaux,  therefore,  may  be  estimated  at 
100,000,000  corks  annually,  worth  about  ^156,338.  Two-fifths 
of  this  quantity  are  exported  to  the  French  colonies,  the  United 
States,  Chili,  India,  &c.,  and  three-fifths  are  used  in  Bordeaux, 
at  the  average  price  of  <£1  4s.  per  thousand. — (Newspaper.) 
Grand  Surgical  Prize  of  the  French  Academy, — This  is  for 
th.Q  preservation  of  limbs  bi/  preserving  the  periosteum.  The  prize 
is  20,000  francs  to  be  awarded,  if  occasion  offers,  in  1866. 
The  following  extract  explains  the  object  of  the  Academy  : — 
Numerous  facts  have  proved  that  the  periosteum  has  the 
power  of  producing  bone.  Recently  some  remarkable  facts  in 
human  surgery  have  shown  that  very  extended  portions  of  bone 
have  been  reproduced  by  the  periosteum  which  remained.  The 
time  appears  to  have  arrived  to  call  the  attention  of  surgeons 
to  this  great  and  novel  study,  which  is  interesting  at  once  to 
science  and  humanity.  The  xlcaderay  made  the  prize  10,000 
francs,  to  which  the  Emperor  added  as  much  more. — (Silliman's

ON  THE  BARK  OF  CEDRELA  FEBRIFUGA,  BLUME. 
By  Dr.  F.  A.  Fluckiger. 
The  author  gives  the  following  description  of  this  bark  derived 
from  a  tree,  belonging  to  Hesperideae-Cedrelese  : 
Pieces  J  metre  in  length,  -05  to  '06  m.  in  width  and  4  to  5 
millim.  in  thickness,  either  freed  from  or  covered  with  the  outer 
bark,  the  latter  resembling  that  of  pine.  The  surface,  where 
the  outer  bark  is  wanting,  is  of  a  rusty  color,  partly  covered 
with  secondary  cork,  and  marked  with  impressions  like  the  so- 
called  conchas  of  cinchona  barks. 
Inner  surface  light  brown  ;  smooth,  fibrous ;  fracture  tough, 
long  fibrous.  Without  a  magnifier,  several  layers  of  periderrna 
are  seen,  covering  a  very  dense  red  brown  parenchyma,  inter- 
sected by  medullary  rays.  Under  the  microscope,  the  periderrna
