COD  LIVER  OIL  AND  LACTO  PHOSPHATE  OF  LIME. 
By  Edward  Chiles. 
This  remedy  is  being  quite  extensively  prescribed  by  physicians, 
and  as  considerable  inquiry  has  been  made  as  to  an  eligible  mode  of 
prescribing  it,  I  will  give  my  experience  in  the  manufacture  of  the 
article,  and  also  a  simple  process  for  making  syrup  of  lacto-phosphate 
of  lime. 
For  a  long  time  I  have  had  demand  for  a  tasteless  cod  liver  oil, 
and  have  been  in  the  habit  of  preparing  it  in  the  form  of  an  emulsion 
with  gum  arabic  and  water,  and  covering  the  odor  with  a  few  drops  of 
essential  oil  of  bitter  almonds. 
Over  a  year  ago  I  found  physicians  were  prescribing  cod  liver  oil 
and  lacto-phosphate  of  lime,  and  I  devised  a  formula  for  it,  based 
on  my  experience  with  the  simple  emulsion  and  the  syrup  of  lacto- 
phosphate  of  lime,  for  which  a  considerable  demand  had  sprung  up. 
The  formula  I  then  devised  has  been  followed  by  me  up  to  the  present 
time,  and  has  invariably  given  satisfaction,  and  produces  an  article 
which  does  not  separate  or  become  rancid. 
I  think,  however,  it  should  be  prepared  extemporaneously  as  pre- 
scribed by  physicians,  and  I  have  not  kept  it  on  hand,  but  prepare  it 
as  wanted,  thus  always  giving  a  perfectly  sweet  article.

Essential  oil  bitter  almonds,  .      six  drops. 
Rub  the  gum,  water  and  syrup  together,  until  a  smooth  mucilage 
is  made,  then  add  the  oil  gradually  with  constant  stirring,  and,  lastly,, 
the  oil  of  bitter  almonds. 
Thus  made,  each  tablespoonful  of  cod  liver  oil  and  lacto-phosphate 
of  lime  contains  four  (4)  grains  lacto-phosphate  of  lime  and  50  per 
cent,  of  cod  liver  oil.  The  gum  in  the  above  should  be  selected, 
ground  and  passed  through  a  seive  of  60  meshes  to  the  inch.  Cod 
liver  oil  and  lacto-phosphate  of  lime,  prepared  in  this  manner,  forms 
a  preparation  free  from  unpleasant  taste  and  odor,  and  enables  the 
practitioner  to  administer  these  valuable  remedies  without  repugnance 
on  the  part  of  the  patient.
