Attention was then directed to the sugar content of thespecimen with better results, for the amount found, whencalculated for dry substance, was per cent. Sincethis amount was not materially increased by first treatingthe infusion with acid, it was probably a glucose sugar. The ash in the absolutely dry specimen was found to be.

Thelocality in which the tree was grown might have had some-thing to do with the amount of salt present. The specimen analyzed was a cross-section of the trunkat the base of the leaves, and in the fresh state was suffi-ciently fleshy to be easily cut with a knife, but in drying itbecame hard and woody.
