** Honeysuckle.” Formerly called ‘‘ Wattung-urree”’ by the aboriginals 
of Cumberland and Camden (New South Wales). 
The bark of this tree has yielded nearly 10.8 per cent. of 
tannic acid, and .7 per cent. of gallicacid. (Mueller.) The author 
has examined a sample of bark of this species obtained in the 
neighbourhood of Sydney. He found 27.38 per cent. of extract, 
of a very deep colour, and no less than 23.25 per cent. of tannic 
acid. (Proc. R.S., NV.S.W., 1887, p. 204.)

The following is an analysis of this bark :—Tannin, 19.48 per 
cent.; extract, 37.91 per cent. (Staiger.) Another experiment 
gave 18.2 per cent. of tannin. It is used for tanning chiefly in 
India.

The author examined a specimen of bark of this species 
brought from Ivanhoe, New South Wales. It contained 17.2 per 
cent. of extract, and 11.58 per cent. of tannic acid. (Proc. &.S., 
1887, p. 205.)
