SECTION I I . Ultimate Analysis.—By this analysis the complete separation of the elementary constituents of the combustible m a t t e r of the coal is effected. I t is of g r e a t value, from t h e fact t h a t it is t h e only means of calculating t h e absolute lieating power of t h e coal. The samples are the s a m e as those used in t h e proximate analysis.
