RESEARCHES ON THE COMPOSITION 
! VI. Oil-cakes from the Manufacture of 
Vegetable Wax. 
In tlie manufacture of vegetable wax from the berries 
of Rhus succedanea and vernicifera two different sorts of oil¬ 
cakes are obtained in the following way : The berries freed 
from the stems are treated in a mortar with a heavy hammer 
until the flesh forms a coarse powder and is entirely se¬ 
parated from the small hard kernels. The whole mass is 
then steamed for a short time and pressed, in a common 
oil press while still hot, whereupon the resulting cakes are 
again broken up and the kernels separated from the pow¬ 
dered flesh with the help of sieves. The kernels are then 
heated on a pan and ground on stone mills to a fine mass, of 
which a small part is mixed with the powdered flesh and 
subjected to'a second pressing. The cakes thus obtained are 
called “ haje dama.” The other portion of the ground ker¬ 
nels is steamed and separately pressed, whereby cakes are 
obtained which are called u mameko dama.” 
Specimens of these cakes which had been obtained from 
Rhus succedanea at Wakayama, were analyzed in our la¬ 
boratory by Mr. E. Yoshida. Their composition was found 
to be, as follows :
