 scope upon which it rests. It is important for steadi-

 counter-die, if the base is to be of metal, are procured, 

 and between these a plate of suitable size and thick- 

 ness is swaged. See Metallic Base and Vulcanite

 of organic compounds, especially nitrogen compounds, 

 which, like ammonium, unite with acids to form salts.
