Morin  prepared  a  volatile  acid  by  submitting  digitalis  leaves 
to  steam  distillation  and  called  it  "  antirrhinic  acid " 
(most  probably  identical  with  valerianic  acid).  He  describes  it 
as  a  colorless,  oily  mass,  soluble  in  alcohol,  but  insoluble 
in  water ;  it  dissolves  very  gradually  in  water,  with  which

taste.     (Journal  de  pharmacie  et  de  chimie  1845,  I>  P-  294-)
