hard wood ashes, yellow pine, — (pinus ahies) — as the type of soft wood 

 ashes ; and wheat-straw as the type of the ashes of the grasses. 



The average quantity of ashes, from 100 parts of dry oak, beech, 

 birch, &,c., is 2.87. Ashes are divided, by the simple process of leech- 

 ing, into two parts, soluble and insoluble in water. 100 parts of hard- 

 wood ashes thus afford — soluble, 13.57 ; insoluble, 86.43. 



100 parts of the soluble contain , 



Carbonic acid, 

 Sulphuric acid. 

 Muriatic acid, 

 Silex, .
