The species used in this experiment were as follows: The chemical composition of woods was determined by the same method used in the preceding experiment, the results of which are shown in Table 1. Table 1 Chemical Composition and Volume Weight of British North Borneo Woods. As shown by the data the chemical compositions of the British North Borneo woods are considered to be compared well with those of the Philippin woods and the Dutch New Guinean woods reported by the author (Cellulose Industry, 1937, 13, 442; Rayon World, 1933, 57, 1), except that some of the former have somewhat more total cellulose and alpha cellulose than the latter. Tankawang had the highest cellulose content and Kapor the lowest. Tankawang had also the highest alpha cellulose content and Rongang the lowest. In general Tankawang gave the low contents of soluble matters in the solvents such as cold water, hot water, mixture of alcohol and benzen, and 1% NAOH and Kapor gave the high. The highest lignin was given by Malan and the lowest was given by Balsa.
