PREPARATIONS  OF  MANGANESE  AND  IRON. 
175 
of  manganese  25  parts  ;  crystallized  carbonate  of  soda  120  parts  ; 
honey  60  parts ;  water  a  sufficient  quantity.  Pills  of  20  centi- 
grammes (3  grains)  are  made  ;  they  keep  easily,  without  becom- 
ing oxidized,  in  well-closed  vessels.  From  two  to  four  are  given 
daily. 
Ferro-manganic  Chocolate. — One  part  of  carbonate  of  iron 
and  manganese  is  first  mixed  with  four  of  sugar,  and  divided  into 
large  lozenges ;  of  these,  100  parts  (grammes)  are  mixed  with 
500  of  chocolate  paste,  in  the  preparation  of  which  100  parts  of 
sugar  have  been  left  out.  This  will  make  800  lozenges,  each  of 
which  contains  about  3  centigrammes  (nearly  half  a  grain)  of 
carbonate  of  iron  and  manganese.  The  chocolate  decomposes 
the  hydrated  carbonate  of  manganese  and  iron  of  the  saccharate 
into  hydrated  sesquioxide  of  iron  and  manganese  ;  there  is  no 
metallic  taste. 
Syrup  of  Lactate  of  Iron  and  Manganese — Take  of  lactate 
of  iron  and  manganese  4  parts ;  powdered  sugar  16  parts  ;  rub 
together,  and  add  of  distilled  water  200  parts ;  dissolve  rapidly, 
and  pour  into  a  matras  over  a  water-bath,  containing  384  parts 
of  broken  sugar  :  filter  the  solution.  This  syrup  contains  about 
15  parts  of  lactate  of  iron  and  5  of  lactate  of  manganese  in 
3000  parts.    One  or  two  spoonfuls  are  taken  daily. 
Lozenges  of  Lactate  of  Iron  and  Manganese  are  made  by  add- 
ing 20  parts  of  the  lactate  to  400  of  fine  sugar,  with  a  sufficient 
quantity  of  water.  The  mass  will  make  840  lozenges  ;  of  which 
six  or  eight  are  taken  daily. 
Syrup  of  Iodide  of  Iron  and  Manganese. — M.  Burin-Dubuis- 
son  forms  a  solution  of  iodide  of  iron  and  manganese,  in  the  pro- 
portion of  one  part  by  weight  to  two  of  water  :  the  proportion  of  the 
salts  is  about  three  of  iodide  of  iron  to  one  of  iodide  of  manga- 
nese. Six  parts  of  this  are  mixed  with  294  of  simple  syrup ;  of 
this,  M.  Petrequin  gives  one  or  two  spoonfuls  daily. 
Pills  of  Iodide  of  Iron  and  Manganese. — Take  of  the  officinal 
solution  prepared  by  M.  Burin-Dubuisson,  16  parts  (grammes ;) 
honey  5  parts;  some  absorbent  powder  9i  parts.  Divide  into 
100  pills.  The  honey  and  the  solution  are  first  mixed,  and 
evaporated  at  first  rapidly,  then  more  slowly,  to  10  parts.  Then 
add  the  powder,  and  divide  the  mass  into  four  parts,  which  must 
be  rolled  in  powder  of  iron  reduced  by  hydrogen  ;  each  of  these
