In my first study of this series, I found that the variation of the length-diameter and length-diameter ratio of trachids in "Akamatsu" wood are considerably regular. The chiefpurpose of the work reported here is to investigate that the analysis of the sample from various portions in a "Akamatsu" tree may show characteristic differences due to the portions in the chemical composition, and also to compare the chemical composition of a rapidly growing tree and that of a slowly growing one. Two trees (B^I and B_2) out of five which had been used in my previous morphlogical study were chosen for the material in this work.Main results are concluded as follows.I. With a few exception, the variation of the chemical compositions which are due to the portions in a tree are slight, and chemical differences between rapidly growing tree and slowly one are also slight.II. But in detail investigation, some regurations in the variations of the chemical composition are found.III. There may be certain relations between the variations of the chemical composition and those of the size of tracheids.
