  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
  Nitroglycerin  \Ni`tro*glyc"er*in\,  n.  [Nitro-  +  glycerinn.] 
  A  liquid  appearing  like  a  heavy  oil,  colorless  or  yellowish, 
  and  consisting  of  a  mixture  of  several  glycerin  salts  of 
  nitric  acid,  and  hence  more  properly  called  {glycerin 
  nitrate}.  It  is  made  by  the  action  of  nitric  acid  on  glycerin 
  in  the  presence  of  sulphuric  acid.  It  is  extremely  unstable 
  and  terribly  explosive.  A  very  dilute  solution  is  used  in 
  medicine  as  a  neurotic  under  the  name  of  {glonion}.  [Written 
  also  {nitroglycerine}.] 
  Note:  A  great  number  of  explosive  compounds  have  been 
  produced  by  mixing  nitroglycerin  with  different 
  substances;  as  dynamite,  or  giant  powder, 
  nitroglycerin  mixed  with  siliceous  earth; 
  lithofracteur,  nitroglycerin  with  gunpowder,  or  with 
  sawdust  and  nitrate  of  sodium  or  barium;  Colonia 
  powder,  gunpowder  with  nitroglycerin;  dualin, 
  nitroglycerin  with  sawdust,  or  with  sawdust  and  nitrate 
  of  potassium  and  some  other  substances;  lignose,  wood 
  fiber  and  nitroglycerin.
