註釋The geological occurrence and method of working the Gulf deposits by means of the Frasch process are described in nontechnical language. The bearing of these deposits on the sulphuric acid situation is discussed and the need pointed out for a determination of the sulphur resources present in the whole Gulf region, with a view to defining a proper adjustment between the needs of the sulphur industry and the sulphuric acid industry.
