AMMar!i',  i873BM'}  Minutes  of  Pharmaceutical  Meetings.  135 
Mr.  Shinn  said  that,  at  the  meeting  held  in  December  last,*  reference  was 
made  to  a  preparation,  somewhat  in  demand  in  this  city,  containing  fifty  per 
cent,  of  cod-liver  oil  and  a  certain  amount  of  lacto-phosphate  of  lime.  Many 
experiments,  before  and  since  that  time,  have  been  made  by  him  to  devise  an 
eligible  method  of  combining  these  remedies  in  a  palatable  form,  resulting  in 
the  following  formula,  made  to  contain  twelve  grains  lacto-phosphate  of  lime  to 
the  ounce  : 
Take  of  Cod  liver  Oil,      .  .  •  Oj, 
Oil  of  Bitter  Almonds, 
"  Peppermint, 
"    Wintergreen,  .  .    each    gtt.  x, 
Powd.  Gum  Arabic,       .  .  ,$iv, 
"     Sugar,  .  .  . 
Solution  of  Lacto-phosph.  Lime,        (gi  to  f,$i)  fsviss, 
Lime  Water,  .  .  .  fsviss. 
Mix  the  gum  and  sugar  in  a  capacious  mortar,  and  make  a  smooth  mucilage 
with  the  lime  water  and  three  ounces  of  the  solution  of  lacto-phosphate  of  lime. 
Add  the  volatile  oils  to  the  cod-liver  oil,  and  gradually  triturate  them  with  the 
mucilage  until  a  perfect  emulsion  is  formed.  Finally,  add  the  rest  of  the  solu- 
tion of  lacto-phosphate  of  lime,  and  mix  thoroughly. 
The  solution  of  lacto-phosphate  of  lime  is  made  as  proposed  by  Mr.  Neer- 
gaard  in  the  Am.  Journal  of  Pharmacy,  June,  1871,  by  saturating  a  solution  of 
lactic  acid  with  freshly  precipitated  phosphate  of  lime. 
The  magma  obtained  from  16  ounces  of  phosphate  of  lime  dissolved  in  muri- 
atic acid,  precipitated  by  ammonia,  quickly  washed  and  pressed,  will  be  suffi 
cient  to  saturate  a  pound  of  the  commercial  acid  mixed  with  4  pints  of  water. 
After  filtering  the  solution  it  is  assayed  by  evaporating  a  fluidounce  to  dryness 
and  weighing  the  resulting  lacto-phosphate  of  lime,  when  it  can  be  made  of  a 
definite  strength.  In  the  formula  given  it  contains  60  grains  to  the  fluidounce, 
which  is  about  equal  to  30  grains  of  phosphate  of  lime,  and  is  of  convenient 
strength.  It  has  a  slightly  acid  taste,  which,  however,  is  not  unpleasant,  but 
rather  renders  the  emulsion  less  cloying  than  if  entirely  sweet.  As  made  by 
the  formula,  the  preparation  will  keep  in  good  condition  for  two  or  three  weeks, 
but  will  eventually  spoil,  as  shown  by  the  blowing  out  of  the  stopper,  although 
the  taste  and  character  are  not  materially  altered. 
If  meant  for  sale  to  the  trade  the  addition  of  about  20  per  cent,  of  alcohol 
renders  it  more  permanent,  and  in  most  cases  may  not  be  therapeutically  ob- 
jectionable. 
This  led  to  some  remarks  upon  the  preparation,  during  which  Mr.  Chiles 
gave  his  formula  (which  is  published  on  page  105  of  the  present  number).  The 
question  of  the  legality  of  selling  the  preparation  was  discussed,  there  being  a 
patent  for  the  manufacture  of  a  similar  compound. 
Mr.  Chiles  stated  that  he  also  prepared  a  lozenge  of  lacto-phosphate  of  lime 
and  pepsin. 
Then  adjourned.  Clemmons  Parrtsh,  Registrar.
