TANS. 321 
The bark contained 3.44 per cent. of tannin as the result of 
one experiment. (Mueller.) The author has examined the barks 
of two varieties of this species—(a) ‘‘ Flooded Gum” or “ Bastard 
Gum,” and (4) ‘Red Gum.” Both are from near Bombala, 
N.S.W., the former yielded 19.4 per cent. of extract, and 9.45 
per cent. of kino-tannic acid, while the latter yielded 20.84 per 
cent. of extract, and 11.35 per cent. of kino-tannic acid. (Proc. 
R.S., N.S. W., 1887, p. 86.) Leaves (oc. ctt., 272-3) yielded (a) 
41.08 per cent. of extract, and 8.28 per cent. of tannic acid; 
(4) 40.61 per cent. of extract, and 16.59 per cent. of tannic acid. 
Tasmania, the extreme south-eastern portion of South Aus- 
tralia, thence to Gippsland and into New South Wales as far as 
Berrima.

“Scribbly Gum.” (For other vernacular names, see ‘‘ Timbers.’’) 
This bark is occasionally used for tanning. Leaves of this 
species yielded the author 47.19 per cent. of extract, and 11.27 
per cent. of kino-tannic acid. (Proc. R.S., V.S.W., 1887, p. 267.)

“ Gum-topped Box.”” (For other vernacular names, see ‘‘ Timbers.”) 
One of the barks occasionally used for tanning by settlers.

Southern Queensland. 
58. Eucalyptus leucoxylon, “v.47, (Syn. &£. sederoxylon, A. 
Cunn.); N.O., Myrtacez, B.FI., iii., 209. 
“Tronbark.”? (For the other numerous vernacular names, see “‘ Timbers.’’) 
The bark of this tree contains 21.94 per cent. of tannic acid. 
(Mueller.) It is hence useful as a tanning material, but only for 
inferior leather, as the extractive substance of the bark imparts a 
dark coloration, and also seems to impair the tanning process. 
The Sydney fishermen sometimes tan their sails and nets with it,
