 high volatile, must be considered as consisting in part of cannel. 



The analyses of the coals from the Fiinfkirchen area, published 

 by Hantken, are ultimate ; reduced to pure coal, as were those from 

 the Steierdorf area, they are : 



The order is ascending. The sulphur is from 1.07 to 6.88 per cent. ; 

 but in the great mass of seams XI. and XII. it does not exceed 2.50. 

 In IV. at Vasas there is but 1.23 but at the Colonic mine it is 6.88. 

 The thickness of the seam and the proportion of sulphur are not in

 yields a great quantity of illuminating gas, that from three other 

 seams about two thirds as much, while that from others is much 

 less. The two analyses for XIV. and for XVI. are from different 

 localities, but only a short distance apart. The local conditions
