This .  preparation  having  odor,  taste  and  color  of  cod  liver  oil 
agitated ,  with  gelatinized  starch  should  give  no  color.  Iodo- 
fcrrated:  Reduced  iron  2  parts,  iodine  4  parts,  and  cod-liver  oil  40 
parts,  are  triturated  in  a  mortar  with  the  addition  of  a  small 
quantity  of  ether  until  the  iodine  is  chemically  combined,  and  a 
black  mixture  results  ;  this  is  then  diluted  with  cod  liver  oil  to  make 
1,000  parts  and  filtered;  contains  0-5  per  cent,  ferrous  iodide,  and 
is  of  a  red-brown  color.  The  trituration  of  the  iron,  iodine  and  a 
small  quantity  of  cod  liver  oil  favors  the  formation  of  anhydrous 
ferrous  iodide,  which  is  readily  soluble  in  the  oil ;  in  the  older 
formulae  for  this  preparation  the  oil  was  warmed  with  the  iodine 
and  iron,  which  caused  the  iodine  to  unite  chemically  with  the  oil, 
leaving  the  iron  in  large  part  unchanged  and  undissolved.—/7.

Ephedra  monostachya. — From  the  ethereal  extract  of  the  herb 
P.  Spehr  succeeded  in  isolating  minute  quantities  of  an  alkaloid* 
From  Ephedra  vulgaris  var.  helvetica,  Hook,  et  Thomp.,  there  have 
been  isolated  two  alkaloids ;  no  color  reactions  are  known  for 
these.  The  following  table  shows  the  differences  between  these 
several  alkaloids  :
