differs from that described in June last, in containing but traces 

 of kino visible to the eye, and consisting of the whole thickness 

 of the bark. The complete difference will be apparent from the 

 following description of the bark now under examination. It 

 reminds me very strongly of virgin cork, more so, in fact, than 

 any other specimen of Eucalyptus bark 1 have examined up to the 

 present time. It is deeply fissured, light (though not quite so 

 light as cork-bark), and these particular specimens certainly might 

 be used as floats for fishermen's nets. It is very soft and elastic, 

 can easily be indented and even torn away by the finger-nail. In 

 a word it is singly inferior cork. Its outer surface has nothing 

 of the hardness characteristic of Ironbarks, though it possesses 

 their rugged, furrowed appearance. Prevailing colour light grey. 

 The corky portion is readily detachable, and about an inch in 

 thickness. The inner bark is of very uniform thickness (about 

 i- 6 - inch), is hard and compact, and contains abundance of fibre of 

 good quality (for Eucalypts). Colour light reddish-brown ; of 

 whole of bark ground up, pure light brown. 



Extract. — Yields 14 - 2 per cent, to water at 100° C. Colour 

 of solution of a deep orange colour, inclining to brown. Becomes 

 turbid when fairly concentrated. Colour of moist residue, different 

 shades of brown. 



Kino-tannic acid — 6*702 per cent.

The wood of this species is used locally for a variety of purposes 

 including rails and wheelwrights work, but the heartwood is 

 considered of no use, so that about a foot of the centre generally 

 has to be left as useless. Bark smoothish and light coloured, the 

 thin reddish-brown, very smooth, outer bark having entirely 

 peeled off in those specimens submitted to analysis. Prevailing
