'^Vu^Tis^yt'""'}     Glyconated  Emulsion  of  Cod-liver  Oil.  339 
Formula  for  Burn-mixture. 
Take  of  the  best  white  glue  (extra)  15  ounces.  Break  it  into  small 
pieces,  add  to  it  2  pints  of  cold  water,  and  allow  it  to  become  soft. 
Then  melt  it  on  a  water-bath,  add  to  it  2  fluidounces  of  glycerin  and 
6  drachms  of  carbolic  acid,  and  continue  the  heat  on  the  water-bath  until 
a  glossy^  tough  skin  begins  to  form  over  the  surface  in  the  intervals  of 
stirring.  The  mixture  may  be  used  at  once,  after  the  glue  is  melted 
and  the  glycerin  and  carbolic  acid  are  added,  but  when  time  allows, 
it  is  advisable  to  get  rid  of  a  little  more  of  the  water,  until  the  proper 
point  is  reached.  On  cooling,  this  mixture  hardens  to  an  elastic  mass, 
covered  with  a  shining  parchment-like  skin,  and  may  be  kept  for  any 
time.  When  using  it,  it  is  placed  for  a  few  minutes  on  the  water-bath 
until  sufficiently  liquid  for  application  (it  should  be  quite  fluid).  Should 
at  at  any  time  require  too  high  a  heat  to  become  fluid,  this  may  be  cor- 
rected by  adding  a  little  water.  It  is  applied  by  means  of  a  broad  brush 
and  forms  in  about  two  minutes  a  shining,  smooth,  flexible  and  nearly 
transparent  skin.  It  may  be  kept  for  any  time,  without  spoiling,  in 
delf  or  earthern  dishes  or  pots  turned  upside  down.

GLYCONATED  EMULSION  OF  COD-LIVER  OIL. 
BY   GEORGE   C.  CLOSE- 
I  am  surprised  at  a  remark  in  the  communication  of  Mr.  McElhenie 
to  the  effect  that  glyconin,  without  oil  of  almonds,  soon  separates.  I 
have  been  in  the  habit  of  keeping  it  for  about  ten  years  past,  and  have 
kept  the  same  parcel,  in  one  instance,  five  years  without  change.  I  do 
not  follow  the  French  formula  exactly,  however,  but  beat  the  yolks 
well  with  a  thin  spatula  previous  to  adding  the  glycerin.  This  is 
much  better  than  mixing  them  with  the  pestle,  as  the  yolks  slip  from 
under  the  pestle  and  are  not  easily  broken  up.  I  first  modified  the  for- 
mula of  Dr.  Andrews  for  Dr.  Sterling  of  Brooklyn. 
The  use  of  the  glyconin  for  the  emulsion  was,  I  believe,  original 
with  me.  It  was  communicated  by  me  to  the  Alumni  Association  of 
the  New  York  College  of  Pharmacy,  in  January,  1874  (p,  35  of  the 
report).    I  had  at  that  time  used  it  for  several  months. 
My  formula  was  communicated  to  the  Kings  County  Medical  Asso- 
ciation by  Dr.  Squibb.     Dr.  George  M.  Beard  and  many  others  were
