As the coals, with the exception of No. 6, showed to the eye little of the 

 usual bi-sulphide of iron, and as a similar suite of samples from the same 

 seam at Old Straitsville, had, upon analysis, revealed much less sulphur, 

 I expressed to Professor Wormley some surprise at the larger per centage 

 of sulphur in the Lost Run samples. He at once repeated the sulphur 

 determinations, and with exactly the same results. This led to a 

 request that he would determine, by analysis, the exact amount of iron 

 there might be in the samples, so that we might see if there was enough 

 to absorb, as a bi-sulphide, the sulphur. This he kindly consented to do, 

 and the results given in the Report for 1869 are here copied, as follows : 



In no case was there iron enough to take up in combination all the 

 sulphur. In No. 5 only one-tenth of the sulphur could be thus taken 

 up. Professor Wormley followed up these researches with reference to 

 the combinations of sulphur in coals with distinguished success, and 

 previous opinions of scientific men in regard to such combinations have 

 been abandoned. Professor Wormley discusses these matters in the 

 Annual Report for 1870. These special investigations may be said to 

 have originated in the finding of a little more sulphur in the Lost Run 

 coals than I had expected to find. 



It is very probable that there may now be new openings into the
