I have submitted the bottle of resin you gave me on your 
recent visit to Sydney, and following is the report of the Curator of 
the Technological Museum on ie substance ? = 
"The Economic Chemist has made a preliminary examination of the 
sample of resin forwarded, and, contrary to expectations, has found 
it not to be an oleo-resin, but apparently a resin in an intermediate 
stage of oxidation. 
Should it be readily obtainable, a larger sample 
would enable him to make a more extended investigation. 
So far it does not seem possible to suggest an economic value for 
it on account of its 'tacky' nature. 
This mitigates against its use 
as a varnish resin, as well as of utilising it for a chewing gum, 
although on treatment it strings well". 
I hope that you will be able to get additional material 
and also a twig of the tree, 
Yours faithfully,
