GLUCOSIDE OCCURRING IN THE TIMBER OF THE RED ASH. 259 
solid, melting at 75-—77°. Upon combustion analysis it 
gave O=58'54, and H=4°43 per cent.: CzgH2s40ie(CO’CHs)<, 
‘or C4ysH4202, requires C = 59°35, and H = 4°35 per cent. 
This result, although not to be accepted as conclusive, 
indicates that the derivative might be a hexa-acetyl deri- 
vative of the glucoside. 
When the glucoside was treated with concentrated nitric 
acid in the cold, it soon reacted with the production of a 
deep brown colour. When the solution was heated it 
became lighter in colour and nitrous fumes were evolved. 
After subsequent dilution with water and boiling, oxalic 
acid was detected in the solution. 
We have pleasure in acknowledging our indebtedness to 
the Curator of the Sydney Technological Museum for the 
material used in the investigation, and Messrs. R. S. 
Hughesdon, B.Sc. and F. Lions, of the Sydney University, 
for kind assistance with the analyses.
