It readily dissolves in cold water, forming a quite clear liquid 

 of a dark orange-brown colour, with a small amount of residue of 

 a Vandyke brown colour. Alcohol (B.P. strength of tincture) 

 yields a reddish-brown liquid, and leaves a granular residue of a 

 dark reddish-brown colour. 



Eucalyptus siderophloia, Benth. (Syn. E. resinifera^ A. Cunn.,

Found in N, S. Wales and Queensland. 



" The specific gravity of this Kino is about 1*413, and the per- 

 centage of tannic 72-13" (Staiger). I regret that I cannot accept 

 this percentage of tannic acid. 



Dr. Joseph Bancroft of Brisbane describes this Kino as exuding 

 plentifully, and at first being in long tears of a pale yellowish 

 colour, which darken into bright red, and eventually into black, 

 becoming more insoluble. (I can endorse this description from 

 examination of New South Wales specimens). He states that a 

 tincture made with 2J ounces to a pint of proof spirit is valuable 

 as an astringent in diarrhcea, but gelatinizes on keeping. I have 

 already pointed out that Kino of this species is little soluble in 

 spirit owing to the gum it contains.

Obviously newer than the two succeeding Kinos. It is of a rich 

 ruby colour, both by reflected and transmitted light. It is mostly 

 in tears, rather horny, and therefore difficult to powder. Colour 

 of powder Sienna brown. 



It dissolves in cold water almost entirely, forming a medium 

 orange-brown liquid. The residue consists of reddish phlobaphene, 

 with a trace of accidental impurity. Colour of residue umber 

 brown. With alcohol (strength of B.P. tinct. Kino), a pale sherry- 

 coloured liquid is formed. The insoluble residue collects into 

 rounded pieces, swells up slightly, and does not disintegrate with
