pcrly  emulsified  after  each  addition,  and  flavored  with  essential  oil  of 
aiiuonds.  The  odor  and  taste  of  the  oil  is  thus  completely  disguised. 
The  emulsion  is  thick,  requiring  a  wide  mouth  bottle,  is  permanent,  a 
slight  separation  which  may  take  place  being  easily  remedied  by  a 
little  agitation,  and  mixes  in  all  proportions  with  water  without  separ- 
ating any  oil  globules;  it  is  easily  made,  palatable,  and  contains  75 
per  cent,  of  codliver  oil. — Proc.  Calif.  Coll.  PAar.,  1882,  p.  31,  32.

Flour  paste  is  made  by  thoroughly  mixing  flour  4  oz,  with  water  1 
pint,  straining  through  a  sieve,  adding  nitric  acid  40  minims,  and 
heating  until  thoroughly  cooked  ;  when  cold,  5  minims  each  of  oil  of 
cloves  and  carbolic  acid  are  added.  In  the  dry  climate  of  California 
the  addition  of  5  per  cent,  of  glycerin  prevents  the  paste  from  drying- 
up  too  soon. — Ibid,

EMULSIONS. 
By  C.  Lewis  Diehl. 
Among  the  many  preparations  that  manufacturers  of  pharmaceutic 
specialties  have  made  much  capital  out  of  in  recent  years,  emulsions  of 
codliver  oil  take  a  very  prominent  place.  From  the  claims  set  forth 
in  their  advertisements — which  may  be  either  by  label,  by  circular,  or 
by  personal  interview  of  the  manufacturer's  agent — one  is  easily  led 
to  believe  that  not  alone  superior  knowledge  and  skill  are  requisite  in 
their  production,  but  also  that  their  successful  production  is  possible 
only  with  the  aid  of  expensive  machinery  and  the  advantages  that  are 
derived  from  abundant  capital  and  a  particularly  favored  market. 
Yet  nothing  is  further  from  the  truth ;  for  while  it  is  not  disputed
