Per (•) () » On account of very high ash, are probably not normal samples. These results, which express the ratio of the vohitile combustiblematter to the fixed carbon are represented graphically by fig. 3. CALOKIFIC VALUE OF PHILIPPINE COALS. 193. Fig. -Chart showing the ratio of the volatile combustible matter to the fixed carbon inPhilippine coals when calculated free from water and ash (pure coal). 194 cox. The relative amounts of fixed carbon and volatile combustible mattervary very little as is shown by the figure. Tlie coals given are repre-sentative of all the Islands and we can assume the average as a fairrepresentation of Philippine coals. ISTot only the amount, but also tliecalorific power of the gaseous portion of these coals is approximately tliesame in all varieties. The following results (Table IV) regarding tliecalorific value of the volatile comliustible matter of coals from have been calculated from worlc already published. T.\BLE IV. Source of t-oal.
