tasteless  if  taken  in  milk  or  warm  coffee ;  if  necessary,  syrups, 
creasote  or  flavoring  substances  may  be  added. 
Castor  oil  emulsion.  Potash  soap  2-0  dissolved  in  distilled  water 
io-o  and  mixed  with  castor  oil  40  o;  flavor  by  addition  of  six  drops 
of  oil  of  peppermint. 
Volatile  oil  emulsions  may  be  easily  prepared  by  the  use  of  soap. 
Oil  of  turpentine  emulsion. — Potash  soap  solution  (10  per  cent.) 
40*0,  oil  of  turpentine  50-0 ;  this  emulsion  separates  no  oil  upon 
dilution  with  water. — Apotheker  Ztg.,  1 891,  471. 
Detection  of  quinine  in  presence  of  phenacetine. — The  latter  sub- 
stance prevents  the  fluorescence  of  quinine  sulphate,  especially  in 
dilute  solutions ;  with  chlorine  water  and  ammonia  phenacetine 
produces  a  yellowish-violet  coloration,  a  mixture  of  quinine  and 
phenacetine  with  these  reagents  producing  a  fine  blue  color.  I  o 
obtain  the  thalleioquin  test,  best  results  are  obtained  with  bromine- 
vapor :  Bromine-vapor  is  allowed  to  act  upon  the  solution  until  a 
faint  turbidity  results,  then  ammonia  is  added,  drop  by  drop ;  pro- 
ceeding in  this  manner  the  green  coloration  appears,  although 
darker  and  inclined  towards  a  violet ;  if  the  test  be  now  agitated 
with  ether  and  allowed  to  stand  a  while,  the  ethereal  layer  will  be 
colored  yellowish-violet  and  the  aqueous  layer  green.- — Sestini  and

Antiseptin  — After  the  exposure  of  Somnal  (claimed  to  be  "  ethyl- 
ated  chloral-urethane,"  but  found  to  be  a  mixture  of  alcohol,  chlor- 
alhydrate  and  urethane)  and  Antinervine  (called  "  Salicyl-brom- 
anilide,"  indicating  a  definite  chemical  compound  of  bromacetani- 
lide  and  salicylanilide,  but  by  analysis  found  to  be  a  mixture  of 
salicylic  acid,  acetanilide  and  ammonium  bromide.  See  Am.  Jour. 
Pharm.,  1891,  408).  Dr.  F.  Goldmann  publishes  an  analysis  of  the 
third  of  Radlauer's  productions,  Antiseptin  or  as  it  is  also  designated 
"  zincum  boro-thymolicum  jodatum."  It  was  found  to  vary  slightly 
in  composition,  but  the  average  analysis  indicated  zinc  sulphate, 
85  0,  zinc  iodide,  2-5,  thymol,  2-5,  and  boric  acid,  io-o. — Pharm.  Ztg.,

Alkaloids  of  the  areca-nut. — Of  the  three  alkaloids  present  two, 
arecoline  and  arecaine,  have  been  described  at  length  in  the  Am. 
Journ.  of  Pharm.,  1889,  133  and  193;  the  third,  aracaidine,  C7  Hn 
N02  H20,  isomeric  with  arecaine,  is  present  to  the  extent  of  o-i  per 
cent. ;  it  forms  colorless,  permanent,  tabular  crystals,  and  is  easily
