vestigations  of  the  Academy.  The  author  having  occasion  to 
obtain  some  information  regarding  the  use  of  this  remedy,  in 
some  parts  of  Russia,  states  that  the  physician  of  the  Princess 
OrlofF  had  this  bug  examined  by  Bach,  of  Boppard,  who  found 
it  to  be  Cetonia  aurata,  which,  according  to  reliable  information, 
has  cured  twenty-one  mad  dogs  and  four  cases  of  hydrophobia 
in  men. 
The  bug  belongs  to  the  family  of  Scarabseides,  or  Lamelli- 
cornes  of  Latreille ;  it  is  flat,  has  a  strong  metallic  lustre,  the 
body  is  of  a  copper  red,  the  upper  part  of  a  golden  green  color, 
it  is  seldom  red  all  over  ;  deepened,  curved  lines  run  across  the 
sheath  wings,  more  or  less  marked  with  white  spots;  size  .6  to  .9 
inches.  When  in  danger,  the  bug  emits  from  all  points  a  grey- 
ish mass  of  a  disagreeable  odor.  Its  larva  lives  generally  in 
the  nests  of  ants  (Formica  rufa,)  and  has  been  collected  in  July 
and  August  for  the  above  purpose ;  one  tea-spoonful  of  the  pow- 
der is  said  to  be  sufficient  for  men  or  dogs.  It  is  worth  while 
to  draw  attention  to  such  a  simple  remedy. 
Empiricism  has  a  vast  field  with  hydrophobia,  and  probably 
no  where  else  has  the  attempt  been  oftener  made  to  find  a  speci- 
fic for  a  disease. — Dr.  WachteVs  Zeitschrift — Wittst.  Viert.

ON  A  KED  CANELLA  BAKK  FROM  THE  WEST  INDIES. 
Br  W.  F.  Daniell,  M.  D. 
Hon.  Member  of  the  Pharmaceutical  Society  of  Great  Britain,  &.c. 
During  a  recent  sojourn  in  St.  Jago  de  la  Vega,  Jamaica,  I 
received,  through  the  kindness  of  my  friend  Mr.  March,  speci- 
mens of  a  red  bark  of  considerable  pungency,  obtained  from  a 
tree,  indigenous  to  the  hilly  districts  in  the  neighborhood  of  the 
town.  The  hot  and  peppery  qualities  of  this  cortical  substance 
led  me  to  infer  that  it  belonged  to  a  species  of  Qanella.  Mr. 
March,  who  is  well  acquainted  with  the  botany  of  the  island, 
had  previously  entertained  a  similar  opinion,  which  was  subse- 
quently confirmed  by  the  discovery  of  the  plant  which  had  fur- 
nished the  bark.  An  examination  of  the  botanical  characters 
indicated  its  identity  or  close  affinity  with  the  Qanella  alba,
