Description: From Introduction Scope of Report: "This bulletin is a report on an investigation of the volatile matter in several typical coals-its composition and amount at different temperatures of volatilization. As the investigation is still in progress and will doubtless include other coals than those already examined, the bulletin may be considered a preliminary report, stating the problems studied, the methods used, and the results thus far obtained."
