class  of  citrates  :  Phosphate,  hypophosphite,  valerianate,  arseniate 
sesquioxide  of  iron  and  several  others,  with  citrates  of  patassa,  soda, 
iithia  and  ammonia.* 
All  these  salts  are  very  soluble  ;  they  all  have  a  greenish  color  and 
present  no  taste  of  iron. 
GLEANINGS  FROM  THE  FOREIGN  JOURNALS. 
By  the  Editor. 
Composition  of  Crude  Cream  of  Tartar. — J.  C.  Sticht  has  analyzed 
a  number  of  samples  of  light-colored  and  red  crude  tartar,  obtained 
from  Spain,  Germany,  Austria  and  Italy,  and  found  its  composition 
to  vary  exceedingly.  Besides  organic  and  other  foreign  matters,, 
amounting  to  from  3-64  to  22*20  per  ct.,  the  light-colored  tartar  con- 
tained between  34  and  88*36  per  ct.  bitartrate  of  potassa,  and  be- 
tween 7*80  and  62  per  ct.  tartrate  of  lime.  The  dark-colored  tartars 
yielded,  besides  from  6  to  56*4:0  per  ct.  coloring  matter  and  other 
impurities,  from  3*60  to  90  per  ct.  bitartrate  of  potassa,  and  from  4 
to  40  per  ct.  of  tartrate  of  lime. —  Wittstein's  Viertelj.  Schr.,  1871,

Purified  Honey. — H.  Michel  has  tried  Heugel's  process  for  purify- 
ing crude  honey,  published  last  year  in  the  Russian  Journal  of  Phar- 
macy, and  obtained  excellent  results.  The  process  is  as  follows :  2 
lbs.  each  of  honey  and  water  are  mixed  with  J  oz.  carbonate  of  mag- 
nesia, frequently  agitated  for  2  or  3  hours,  and  then  filtered  through 
a  double  filter  made  of  ordinary  white  filtering  paper.  The  clear 
filtrate  is  heated  for  some  time  to  boiling,  the  scum  carefully  removed, 
afterwards  the  liquid  evaporated  upon  a  steam-bath  to  a  syrupy  con- 
sistence. Honey  of  roses  may  be  made  from  crude  honey  as  follows, 
thus  avoiding  more  than  one  evaporation  :  The  infusion  of  2  oz.  rose 
leaves  in  24  oz.  hot  water  is  expressed  and  strained  after  12  hours ; 
the  cold  liquid  mixed  with  24  oz.  crude  honey,  and  afterwards  with  2 
drachms  of  carbonate  of  magnesia  ;  the  mixture  is  frequently  agitated 
for  2  or  3  hours,  filtered  and  evaporated  in  a  steam-bath  to  the  proper 
consistence.  —Ihid.,  446. 
*The  solubility  of  phosphate  of  sesquioxide  of  iron  in  citrate  of  ammonia  was 
noticed  in  1859  by  Mr.  A.  F.  Haselden  and  myself.  See  Amer.  Journ.  Fharm.
