bath,  transferring  to  a  warm  mortar,  mixing  with  .5  gm.  powdered 
acaciaand  emulsifying  after  the  addition  of  7-5  gm.  luke-warm  water  ; 
this  accomplished,  10  gm.  more  of  the  warm  water  are  added  and 
the  mortar  with  contents  allowed  to  cool  before  adding  the  remain- 
ing quantity  of  water.  If  the  warm  emulsion  be  diluted  at  once 
with  the  full  quantity  of  water,  the  salol  will  separate  as  a  crust 
in  the  vessel  and  agitation  will  not  loosen  it ;  prepared  as  directed, 
the  salol  separates  as  a  very  fine  powder,  and  is  easily  incorporated 
by  agitation.  The  emulsion  has  the  odor  of  salol,  but  is  nearly 
tasteless;  sweetened  with  syrup  it  is  a  very  desirable  preparation 
for  children.  For  dispensing  a  concentrated  emulsion  is  convenient 
since  it  is  also  permanent. 
Salol- glycerin. — Ten  gm.  salol,  5  gm.  acacia  and  7-5  gm.  water 
are  emulsified  as  above  and  then  after  cooling  diluted  with  glycerin 
to  make  100  gm.  It  forms  a  thick,  milky  mixture,  separating  the 
salol  as  a  very  fine  powder  which  is  readily  incorporated  again. 
Useful  in  throat  affections,  and  adapted  for  application  with  a  brush. 
Salol-vaselin. — Made  by  melting  1  gm.  salol  with  9  gm.  vaselin 
and  stirring  until  cool.  Used  for  chapped  hands  and  lips,  also  for 
rough  skin. — A.  Suchomel,  Pharm,  Post.,  1892,  954,  955. 
Antinonnin  is  the  name  given  to  a  paste  containing  fifty  per 
cent,  ortho-dinitrocresol-potassium  ;  to  prevent  the  paste  from  dry- 
ing out  a  small  quantity  of  soap  is  added,  as  the  absolutely  dry  salt 
is  an  explosive  compound.  Proposed  first  as  a  means  of  protecting 
trees  from  the  ravages  of  insects,  it  has  since  been  found  to  be  a 
poison  for  all  forms  of  lower  animal  life  ;  in  quantities  of  less  than 
one  milligram  the  pure  chemical  is  a  sure  destroyer  of  mice,  while 
two  centigrams  will  suffice  for  rats,  in  consequence  of  which  phos- 
phorus pastes  are  to  be  superseded.  As  a  preservative  of  wood 
favorable  experiments  are  reported.  It  is  generally  used  in  aqueous 
solution  2  :  500,  in  which  strength  it  can  be  advantageously  used  in 
the  treatment  of  itch  ;  for  the  development  of  poisonous  symptoms 
very  much  stronger  solutions  must  be  used  (1  :  30  applied  with  a 
brush  produced  poisoning  of  a  horse).  An  objectionable  property 
of  the  remedy  is  the  intense  yellow  color  which  is  in  some  cases 
removed  with  difficulty. — Sudd.  Apoth.  Ztg.,  1892,  233  and  241. 
Indicator  in  alkaloidal  assaying. — The  alkalimetric  estimation  of 
the  alkaloids  extracted  in  a  crude  state  has  been  very  unsatisfactory,
