physicians  ;  but  few  American  pharmacists  have  been  able  to  prepare 
it,  not  knowing  the  nature  of  the  preparation.  If  the  fraternity 
would  follow  this  feeble  effort  in  disseminating  such  knowledge,  I 
am  sure  it  would  be  productive  of  very  good  results,  for  "  In  union 
there  is  strength."

GLEANINGS  FROM  THE  EUROPEAN  JOURNALS.

Corrosive  sublimate  and  chloride  of  sodium.  Julius  Miiller  ob- 
served that  all  preparations  of  mercury,  the  insoluble  sulphide  alone 
excepted,  are  dissolved  by  a  solution  of  chloride  of  sodium  in  a  form 
in  which  they  do  not  precipitate  albumen.  A  concentrated  aqueous 
solution  of  one  part  corrosive  sublimate  and  ten  parts  chloride  of 
sodium,  which  does  not  precipitate  albumen,  acquires  this  property 
again  on  being  largely  diluted  with  water.  Instead  of  the  double 
chloride  of  sodium  and  mercury,  which  has  of  late  been  recommended, 
Miiller  recommends  to  dissolve  one  part  corrosive  sublimate  and  one 
hundred  parts  chloride  of  sodium  in  distilled  water,  and  evaporate 
the  solution  to  dryness.  This  saline  mixture  contains  one  per  cent* 
corrosive  sublimate,  produces  with  caustic  potassa  a  white,  not  a 
yellow,  precipitate,  is  not  effected  by  solution  of  albumen,  and  has 
been  given  with  good  results  in  tablespoonful  doses  every  two  hours, 
in  a  solution  made  of  6  grm.  (90  grains)  in  180  grm.  (6  oz.)  of  water.

Purification  of  carbonic  acid  gas.  Dr.  Emil  Pfeiffer  recommends 
to  pass  the  gas  generated  from  limestone,  through  olive  oil,  in  which 
a  number  of  pieces  of  pumice  stone  has  been  introduced.  The  same 
agent  has  been  found  of  good  service  in  the  Paris  gas  factory,  where 
Mallet  introduced  it  in  the  direct  preparation  of  strong  solution  of 
ammonia,  for  the  removal  of  carbohydrogens  and  empyreumatic  oils. 
The  volatile  odorous  principles  may  be  removed  by  heat,  and  the  oil 
used  for  a  long  time. — Ibid.,  223. 
Ammonia  salts  prevent  the  complete  precipitation  of  phosphoric  acid 
by  molybdate  of  ammonia.  Dr.  J.  Konig  found  that  the  phosphates 
of  iron,  alumina  and  lime,  are  soluble  in  solutions  of  oxalate  and 
citrate  of  ammonia,  in  consequence  of  the  formation  of  soluble  double 
salts.    Large  quantities  of  ammonia  salts  interfere  with  the  complete
