If  copper  is  administered  in  proper  doses  it  does  not  affect 
the  intestinal  canal,  it  acts  in  a  gentle,  very  peculiar  manner  un- 
like any  other  medicine.  It  is  a  substance  that  assimilates  very 
well  in  the  human  organism.  Copper  is  equally  advantageous 
in  acute  and  chronic  diseases,  both  in  those  which  consist  pe- 
culiarly in  a  single  affection  of  the  organism,  as  well  as  those 
which  have  their  origin  in  a  primitive  constitutional  disease, 
and  an  idiopathic  affection  of  an  organ. — Repertoire  de  Phar-

ON  THE  PREPARATION  OF  CONCENTRATED  ALCOHOL. 
Ry  M.  Eugene  Fegeux. 
Alcohol  of  40°  (Cartier),  is  a  reagent  which  the  pharmaceu- 
tist often  needs  in  the  analyses  he  is  called  to  make.  The  follow-

excellent  results : — 
Take  one  kilogramme  (2  flb  3  oz.)  of  carbonate  of  potash  of 
commerce,  one  kilogramme  of  quicklime ;  mix  with  three  litres 
of  alcohol  of  36°,  putting  the  whole  in  the  boiler  of  an  alembic  ; 
and  commence  the  distillation,  being  careful  to  test  the  first  pro- 
duct with  the  alcoholmetre.  It  seldom  happens  that  the  first 
portion  is  as  strong  as  40°,  and  it  is  necessary  to  return  this  to
