The eudesmin was removed from an aqueous solution of the kino 
by agitating with ether, separating this, evaporating the ether, 
and weighing. The following is the percentage analysis of this kino

The residue from the first solution of the saccharine exudation 
consisted largely of debris, wood, bark, etc., this was boiled with 
water, a small quantity of gum was obtained, also a little tannin, 
but no other constituent was detected likely to be of importance. 
The principal results arrived at from the foregoing research are 
as follows:— — 
(a) That the manna is derived from the bark of £. punctata. 
(6) That the kino is derived from the wood and not from the bark. 
(c) That the principal sugar in these exudations is raffinose 
(melitose), and is chemically the same as that investigated 
from other Eucalypts and from other sources. 
{d) That the dark saccharine exudation from this tree contains 
at least two other sugars besides raffinose, one readily 
fermentable, the other not so readily. 
({e) That those Eucalypts not containing eudesmin ete. in their 
kinos do not give manna. 
{f) That some of the Eucalypts belonging to the Renanthere 
contain a yellow dye in their leaves allied to quercetin, 
and in some respects to aromadendrin. 
(g) That the kino of Z. punctata contains eudesmin but not 
aromadendrin,
