The percentage of ash in the Sasti coals is in some instances less, and 

 in no case much in excess of the Raniganj average, which is 14'5. 



(c) Sulphur. — The sulphur was only determined in a few samples, 

 and the highest return is that of the Warora coal. The pyrites occur 

 in nests, and as spangling the surface of occasional pieces of coal for 

 several square inches in extent. The larger masses might be picked out 

 by hand, but the pyrites that occur as minute crystals on the laminae 

 of the coal could not be separated unless the coal were crushed, and 



then subsequently washed.
