320 AUSTRALIAN NATIVE PLANTS. 
51. Eucalyptus cosmophylla, /v.47., N.O., Myrtacez, B.FI., iii., 
225. 
The ordinarily dry leaves gave 13 per cent, of tannin accord- 
ing to a solitary experiment; equal to nearly 15 per cent. in 
absolutely dry leaves. (Mueller and Rummel.) 
South Australia. 
52. Eucalyptus doratoxylon, /v.17.; N.O., Myrtacez, B.FI., iii., 
249.

53. Bucalyptus globulus, Zad://.; N.O., Myrtacex, B.FL., iii., 
225. 
The well-known ‘‘ Blue Gum.” (For other vernacular names and 
synonyms, see ‘‘ Timbers.”’) 
This bark contains 4.84 per cent. of kino-tannic acid. (Mueller 
and Hoffmann.) Count Maillard de Marafy has suggested that 
the leaves of this species can be used as a substitute for Sumach. 
“Leaves of Z. globulus, taken from a plantation near Alexandria, 
and pulverised like Sumach, when used upon cotton and wool in 
the same proportion as the best Sicilian Sumach, gave an intense 
black that left nothing to be desired.”
