 Fragment a, do not apply to the above desi ription oi these organs, bu1 rather u> those from the tree having fruits 

 ir to those figured by Mui Uei 1/ ii t it.).

 rotatory pinene and laevo-rotatory aromadendrene. It also contained a very 

 little cineol, some alcoholic bodies, together with a small amounl oi volatile 

 aldehydes. Neithei phellandrene nor 1 rystallised eudesmol was detected.
