Publisher's Synopsis
Excerpt from A Study of the Forms in Which Sulphur Occurs in Coal
There are many indications that organic sulphur compounds form a large part of the sulphur in coal, but the nature of these compounds or the amount of sulphur SO combined has never been determined prior to this investigation. Since the organic sulphur had its source in the protein sulphur of the plant and animal life from which the coal was formed, it is probable that these compounds in the coal are degradation products of the original material.
