Ferrum  carbonicum  saccharatum.  5  parts  of  sulphate  of  iron  and 
4  p.  bicarbonate  of  sodium  are  separately  dissolved  in  hot  water,  the 
solutions  mixed  and  the  air  excluded.  The  precipitate  is  washed  by 
decantation,  then  mixed  with  8  parts  of  sugar,  evaporated  to  dryness 
and  powdered.    It  contains  20  per  cent,  of  carbonate  of  iron. 
Ferrum  chloratum.  Granulated  protochloride  of  iron,  obtained  by 
rapidly  evaporating  a  recently  prepared  solution  until  a  pellicle  is 
formed,  adding  1  part  of  hydrochloric  acid  for  every  520  parts  used 
in  dissolving  the  iron,  and  evaporated,  with  constant  stirring,  to  dry- 
ness. 
Ferrum  iodatum  saccharatum.  A  solution  of  iodide  of  iron,  pre- 
pared from  3  p.  powdered  iron,  10  p.  distilled  water,  and  8  p.  of 
iodine,  is  filtered  upon  40  p.  milk  sugar,  evaporated  to  dryness  and 
powdered.    Contains  20  per  cent,  of  ferrous  iodide. 
Ferrum  oxydatum  saccharatum  solubile.  20  parts  of  solution  of 
sesquichloride  of  iron  (sp.  gr.  1*480  to  1*484,  containing  43*5  per  ct. 
anhydrous  ferric  chloride)  are  mixed  with  20  p.  simple  syrup;  40  p. 
of  soda  solution  (spec.  gr.  1*330  to  1-334,  containing  30  to  31  per  ct. 
NallO)  are  gradually  added  and  the  mixture  set  aside  for  24  hours. 
The  clear  liquid  is  mixed  with  300  parts  of  hot  distilled  water,  the 
precipitate  washed  first  by  decantation,  afterwards  upon  the  filter,  and 
allowed  to  drain.  After  the  addition  of  90  parts  of  powdered  sugar, 
the  precipitate  is  dried  in  a  water-bath,  and  enough  sugar  added  to 
make  the  whole  weigh  100  parts,  which  contain  ferric  oxide  equal  to 
3  parts  of  metallic  iron. 
It  is  a  reddish  powder,  of  a  sweet  and  slightly  ferruginous  taste, 
completely  soluble  in  5  parts  of  water,  the  solution  having  a  slight 
alkaline  reaction. 
Ferrum  sesquichloratum.  Fe2Cl6+6H20  in  crystalline  masses, 
completely  soluble  in  water,  alcohol  and  ether. 
Gelatina  Carrageen.  1  part  of  Irish  moss  is  boiled  for  half  an 
hour  with  40  p.  water,  and  expressed.  To  the  strained  liquid  2  parts 
of  sugar  are  added,  and  the  whole  evaporated  to  10  parts. 
G-elatina  Liehenis  lslandici.  Prepared  like  the  foregoing,  from 
3  parts  of  Iceland  moss,  100  p.  of  water,  and  3  p.  of  sugar.  The 
result  is  10  parts.
