WYITH'S  DIALYZED IRON. 
( FERRUM  DIALYSATUM) 
A  PURE  NEUTRAL  SOLUTION  OF  IRON  IN  THE  COL 
LOID    FORM.      THE  RESULT  OF  ENDOSMOSIS 
AND  DIFFUSION  WITH  DISTILLED  WATER. 
PREPARED  SOLELY  BY

This  article  possesses  great  advantages  over  every  other  ferruginous  preparation 
heretofore  introduced,  as  it  is  a  solution  of  Iron  in  as  nearly  as  possible  the  form 
in  which  it  exists  in  the  blood.  It  is  a  preparation  of  invariable  strength  and 
purity,  obtained  by  a  pro  -ess  of  dialyzation,  the  Iron  being  separated  from  its  acid 
combinations  by  endosmosis,  according  to  the  law  of  diffusion  of  liquids.  It  has 
no  styptic  taste,  does  not  blacken  the  teeth,  disturb  the  stomach,  or  constipate  the 
bowels.    It  affords,  therefore,  the  very  best  mode  of  administering 
in  cases  where  the  use  of  this  remedy  is  indicated. 
The  advantages  claimed  for  this  form  of  Iron  are  due  to  the  absence  of  free  acid, 
which  is  dependent  upon  the  perfect  dialyzation  of  the  solution.  The  samples  of 
German  and  French  Liquor  Ferri  Oxidi  Dialys.  which  we  have  examined,  give  acid 
reaction  to  test  paper.  If  the  dialyzation  is  continued  sufficiently  long  it  should  be 
tasteless  and  neulral. 
The  appliances  we  have  perfected  enable  us  to  prepare  this  solution  on  a  large 
scale  and  in  the  most  efficient  state. 
Full  directions  accompany  each  bottle. 
In  addition  to  the  Solution  we  prepare  a  Syrup  which  is  pleasantly  flavored,  but 
as  the  Solution  is  tasteless,  we  recommend  it  in  preference.  Physicians  will 
find  our  DIALYZED  IRON  in  all  the  leading  drug  stores  in  the  United  States 
and  Canada. 
It  is  put  up  in  bottles  retailing  for  ONE  DOLLAR,  containing  sufficient  for  two 
months'  treatment.  Large  size  is  intended  for  Hospitals  and  dispensing  ;  retail 
at  $3.00.       Price  List,  &c,  &c,  sent  on  application.
