OTHER FORMS OF LIME 



from a magnesian limestone is an excellent 

 material for correction of soil acidity, on 

 account of its physical condition. Its ex- 

 posure to the air causes much of the hydrate 

 to change to an air-slaked form, and its 

 value per ton lies somewhere between that 

 of very finely pulverized limestone and 

 hydrated lime.
