desirable  to  find  a  method  of  research,  not  only  to  explain  the  connec- 
tion of  contact  actions  with  other  kinds  of  chemical  change,  but  also 
even  of  the  mechanism  of  the  chemical  change  itself. — Jour.  Chem.

PARAQUINANISOIL  AND  DERIVATIVES. 
By  Z.  H.  Skeaup. 
Paraquinanisoil  is  best  prepared  by  heating  a  mixture  of  78  gms. 
anisidine,  50  gms.  nitranisoil,  320  gms.  glycerol,  and  125  gms.  sul- 
phuric acid  for  two  hours ;  50  gms.  more  of  sulphuric  acid  are  added, 
and  the  heating  continued  for  two  hours  longer.  The  product  is  then 
diluted  with  water,  distilled  with  steam,  and  the  residue  treated  with 
potassium  dichromate,  which  causes  a  precipitation  of  quinanisoil 
chromate;  this  is  then  purified.  Pure  quinanisoil  forms  a  yellowish 
oil,  which  soon  acquires  a  green,  then  a  red  dish- violet  color ;  it  boils 
with  slight  decomposition  at  304-305°  (uncorr.).  Sp.  gr.  at  20°  == 
1'542  (water  at  20°  =  1).  Paraquinanisoil  hydrochloride,  C9NHOMe,- 
HC1  +  2H20,  forms  colorless  prisms,  readily  soluble  in  cold  water 
and  hot  alcohol,  insoluble  in  ether.  It  loses  its  water  of  crystallization 
over  sulphuric  acid.  The  chromate  forms  long,  gold-colored,  silky 
needles,  which,  when  exposed  to  air,  lose  their  lustre  and  become 
brownish ;  it  is  very  sparingly  soluble  in  cold  water.  The  neutral 
sulphate,  add  sulphate,  tartrate,  and  other  salts  are  described.  The 
aqueous  solutions  of  the  salts  all  show  a  blue  fluoresence.  Chlorine- 
water  and  ammonia  act  on  the  salts,  giving  the  green  color  character- 
istic of  quinine  compounds. 
Paraquinanisoil  methiodide  crystallizes  from  water  in  long, 
gold-colored,  lustrous  needles,  which  melt  with  evolution  of  gas 
at  235°.  It  is  insoluble  in  ether,  readily  soluble  in  hot  water  and 
alcohol. 
Thalline,  C9H10MeNO,  is  prepared  by  reducing  quinanisoil  with  tin 
and  hydrochloric  acid;  it  forms  thick,  white  prisms,  sparingly  soluble 
in  water  and  light  petroleum,  very  readily  in  alcohol,  ether  and 
benzene.  It  melts  at  42-43°,  and  boils  at  283°  (uncorr.;  bar.  = 
735  mm.).  When  treated  with  ferric  chloride  or  other  oxidizing  agents, 
it  acquires  first  a  yellow,  afterwards  a  dark  emerald-green  color.
