thesisSulphur exists in metallurgical coke as a source of annoyance and difficulties in the economic progress of the metal industries. It ie present in coal in several different forms under two heads as organic and inorganic sulphur. The percentage of the forms vary widely in different coals. In the manufacture of coke, varying ajnounte of sulphur a=a retained by the same coal under different methods of carbonization, and, by different coals under the same method of treatment . It is desirable to know the factors that influence the distribution of the element between the gases and the residues of coal in the manufacture of metallurgical coke, and, for that reason it is an important problem at present which means a saving of millions of dollars to the metal industry. Analyses of the forms of sulphur in several samples of Utah coals appear elsewhere in this paper. The samples were received from the offices of the yards in Salt Lake Oity and analyzed according to the methods used by Prof- S. W. Parr and A. R. Powell on several Eastern coals
