Clarified  Honey  is  obtained  by  E.  Dannenberg,  of  unexception- 
able quality,  by  diluting  the  crude  honey  with  half  its  weight  of  water, 
boiling  for  15  or  30  minutes,  according  to  the  quantity  operated  upon, 
the  scum  being  carefully  removed,  and  then  adding  five  or  six  times 
•sufficient  cold  water  to  interrupt  the  boiling  for  not  over  half  a  minute. 
After  boiling  for  another  15  minutes,  the  hot  honey  is  strained  and 
-evaporated.  Thus  prepared  the  author  has  kept  the  honey  unaltered 
for  over  two  years. — Archiv  d.  Phar.,  Sept.,  187^,  276. 
Extract  of  Hyoscyamus. — R.  Huguet  observed  in  an  old  extract 
a  large  number  of  crystals,  the  principal  form  of  which  was  the  regular 
octohedron,  in  some  cases  with  combinations  of  the  cube.  By  incinera- 
tion he  obtained  between  22*28  and  31*5  per  cent,  of  fixed  residue, 
containing  from  5*12  to  8*4  of  potassium  chloride. — Rep.  de  Phar., 
1876,  p.  545. 
Mercurial  Ointment. — E.  Dannenberg  recommends  for  the  rapid 
extinction  of  the  mercury  to  triturate  500  grams  with  about  80  grams 
of  lard  and  15  to  20  grams  of  olein,  after  which  the  remaining  fat  is 
added.— Archiv  d.  Phar.,  Sept.,  1876,  256. 
The  Preparation  of  Sulphide  of  Iron  is  best  accomplished, 
according  to  Dr.  Mehu,  by  mixing  two  parts  of  finely  powdered  pyrites 
or  bisulphide  of  iron  with  one  part  of  powdered  iron,  and  heating  the 
intimate  mixture  in  a  Hessian  crucible  to  redness  for  half  an  honr.  It 
is  unnecessary  to  increase  the  heat  to  fusion  ;  a  grey  mass  is  obtained 
which  is  easily  pulverized,  and  in  contact  with  hydrochloric  acid,  copi- 
ously evolves  sulphuretted  hydrogen. — Zeitschr.  d.  cest.  Apoth.  Ver., 
1876,  p.  413. 
Adulterated  Sulphate  of  Quinia  has  been  noticed  in  France  by 
Dr.  P.  Jaillard  ;  it  contained  the  almost  incredible  amount  of  70  per 
cent,  of  potassium  nitrate.  The  adulterated  article  had  the  appearance 
of  the  pure  salt,  but  possessed  a  bitter  and  saline  taste,  was  to  a  large 
extent  soluble  in  water  at  the  ordinary  temperature,  only  in  part  soluble 
in  strong  alcohol.  The  aqueous  solution  heated  with  an  acid  solution 
of  ferrous  chloride,  oxidizes  the  latter  readily.  The  salt  heated  upon 
the  blade  of  a  knife  deflagrates  and  leaves  a  white  ash. — Jour,  de  Phar.
