founded  with  the  well-known  saponaceous  emulsion  of  oil  of  turpen- 
tine, sometimes  called  "  camphor  cream,"  we  will  provisionally  call 
"  milk  of  camphor." 
It  consists  essentially  of  a  mixture  of  a  fatty  oil,  oleic  acid  and 
spirit  of  ammonia  with  water,  and  the  base  is  practically  the  same 
as  petrox,  for  which  a  formula  was  given  in  this  Journal  some  time 
ago.    (American  Journal  of  Pharmacy,  1901,  p.  220.) 
A  typical  formula  for  a  preparation  of  this  kind  would  be : 
Spirit  of  ammonia   5  grammes 
Oleic  acid   10 
Oil  of  cotton-seed   20      *  " 
Camphor   1 
Water  to  make   150 
To  the  cotton-seed  oil,  in  a  dry  bottle  or  suitable  container,  add 
the  oleic  acid,  followed  by  the  spirit  of  ammonia.  In  this  mixture 
the  camphor  is  readily  dissolved.  Now  add  the  water  in  quantities 
of  from  5  to  10  c.c.  at  a  time,  and  shake  or  stir  until  a  uniformly 
smooth  emulsion  has  been  formed.  This  preparation,  like  the  pre- 
ceding one,  can  be  varied  by  using  a  mineral  oil  or  oil  of  sweet 
almonds,  or  by  substituting  any  more  desirable  perfume  or  odor  for 
the  camphor. 
Among  the  more  desirable  preparations  of  glycerin,  a  mixture 
of  equal  parts  of  glycerin,  rose  water  and  solution  of  peroxide  of 
hydrogen  is  probably  the  most  satisfactory.  The  latter  ingredient 
in  this  preparation  is  a  particularly  useful  one,  and  contributes  very 
materially  to  its  efficiency. 
The  following  may  be  taken  as  a  type-formula  for  "  glycerin 
Boil  the  Irish  moss  on  a  water-bath  with  sufficient  water  to  make 
420  c.c.  of  jelly  and  strain ;  while  still  warm  add  the  glycerite  of 
boroglycerin.  When  nearly  cold  add  any  desirable  perfume  or  flavor. 
Here  again  the  resulting  product  may  be  varied  by  substituting 
agar-agar,  gelatin,  tragacanth,  starch  or  quince-seed  for  the  Irish 
moss  ;  also  by  replacing  the  boroglycerin,  in  whole  or  in  part,  by 
glycerin.  The  perfume  may  be  varied  at  will,  and  may  include  any 
one  of  the  thousand  and  one  available  odors.
