AROMATIC  SYRUP  OF  GALLS. 
of  making  aluminium  on  a  large  scale,  but  by  producing  sodium 
at  a  cheap  rate  have  brought  its  valuable  properties  within  the 
reach  of  scientific  men  as  a  re-agent. 
p  In  fact,  with  the  energy  of  potassium,  this  metal  presents 
none  of  the  difficulties  in  its  preparation  peculiar  to  the  former. 
M.  Deville's  experiments  show  that  it  may  be  made  almost  as 
easily  as  zinc,  that  it  may  be  exposed  to  the  air  in  a  fused  state 
without  inflaming,  and  may  flow  in  the  fluid  state  from  the  ap- 
paratus used  in  making  it. 
M.  Dumas  alludes  to  the  reduction  of  chlorides  as  a  feature  in 
metallurgy  likely  to  be  productive  of  new  results.  He  considers 
Marseilles  as  the  best  location  for  the  manufacture  of  aluminium, 
owing  to  the  cheapness  of  materials  obtainable  there. 
In  concluding,  M.  Dumas  called  the  attention  of  the  Academy 
to  the  sonorousness  of  aluminium,  which  can  only  be  compared 
to  that  of  the  most  sonorous  bronzes,  such  as  bell-metal,  which 
has  not  been  noticed  in  any  other  pure  (unalloyed)  metal,  thus 
adding  another  to  the  singular  features  of  this  curious  metal.

AROMATIC  SYRUP  OF  GALLS. 
The  following  preparation  has  been  considerably  employed  in 
Philadelphia,  and  is  attributed  by  some  to  the  late  Dr.  Joseph 
Parrish,  of  this  city.    It  is  used  in  the  diarrhoea  of  children. 
Take  of  Galls,  powdered,  half  an  ounce. 
Cinnamon,  bruised, 
Nutmegs,  bruised,  of  each     two  drachms. 
French  brandy,  half  a  pint. 
Sugar,  in  small  lumps,  two  ounces  (troy). 
Macerate  the  solid  ingredients  in  the  brandy  for  twenty-four 
hours,  throw  on  a  filter,  and,  when  drained,  add  diluted  alcohol 
till  half  a  pint  in  all  has  passed. 
Having  placed  the  tincture  in  a  shallow  capsule,  suspend 
the  sugar  over  it,  on  a  slip  of  woven  iron  wire,  and  then  inflame 
the  tincture.  The  flames  proceeding  from  the  burning  alcohol 
fuse  the  sugar  and  scorch  it  so  as  to  produce  a  portion  of  caromel, 
and  as  it  melts  it  falls  into  and  dissolves  in  the  liquid  beneath. 
When  the  combustion  stops  the  whole  should  be  stirred  and  filtered 
for  use. — Editor  Amer.  Jour.  Pharmacy.
