Geranium  Oil  and  its  Substitutes. 
By  Lyman  F.  Kebler. 
All  varieties  of  geranium  oils  readily  available  in  this  country 
were  purchased  as  near  the  source  of  production  as  possible.  The 
oils  were  examined  with  a  view  of  ascertaining  if  mixtures  of  these 
oils  could  readily  be  detected.  Twelve  samples  were  secured  and 
the  analysis  justified  the  conclusion  that  a  judicious  mixer  has  the 
chemist  at  a  decided  disadvantage. 
A  Note  on  Some  New  Reactions  for  Antipyrin  and  Salophen. 
By  George  M.  Beringer. 
The  author  proposes  the  following  tests : 
Antipyrin. — On  agitating  a  small  quantity  of  antipyrin  with  some 
solution  of  chlorinated  soda,  the  odor  of  the  chlorine  oxides  soon 
disappears  and  the  liquid  slowly  acquires  an  odor  like  that  of  essen- 
tial oil  of  almonds.  Furthermore,  on  agitating  some  antipyrin  with 
chlorine  water,  the  color  and  odor  of  chlorine  promptly  disappears 
and  there  is  formed  a  copious  white  amorphous  precipitate,  evidently 
a  chlorine  substitution  product. 
Salophen  : — -i  gm.  is  boiled  for  one  minute  with  2  c.c.  of,  solution 
of  sodium  hydroxide  (1-2)  then  allowed  to  cool  and  5  c.c.  of  solu- 
tion of  chlorinated  soda  added.  There  is  immediately  produced  a 
deep  and  bright  green  color.  After  some  time  this  changes  to  a 
deep  mahogany  brown.  This  change  to  a  brown  color  takes  place 
slowly  in  the  cold,  but  more  rapidly  if  the  solution  is  boiled.  On 
supersaturating  the  solution,  either  when  green  or  when  brown, 
with  a  concentrated  mineral  acid,  the  color  changes  to  a  bright 
scarlet  and  then  slowly  fades  to  a  red  orange  or  mandarin  color.
