 Tannic acid determination (Lowenthal), 56*888 per cent. 



Mr. Staiger says of a Queensland sample of this kino : — " The 

 specific gravity is about 1*395, and the percentage of tannin 53*33. 

 The solution in water when evaporated yields brownish scales." 



Kinos not examined by me, yet, from the experiments of others, 

 evidently falling in the Turbid Group. 



Eucalyptus calophylla, R. Br., B.F1. iii. 255. 

 " Red Gum " of Western Australia. 



Dr. Wiesner says of this kino : — " Readily soluble in water ; 

 solution yellow, slightly acid, becomes turbid on cooling, free from 

 gum-resin. Irregular grains, light brown or red." 



Baron von Mueller says : — " Kino-liquid of treacle consistence 

 is obtained in considerable quantity by tapping the tree ; it is 

 caught in casks as material for tanning and dyeing purposes, and 

 fetches from £20 to .£25 per ton in the London market. This 

 liquid indurates, and can, like the dry kino of this and other 

 Eucalypts, be used also medicinally" ( Eucalyptographia ). Soluble 

 to the extent of 70*80 per cent, in cold water (Mueller). 



This species is mainly alluded to in the following passages, but 

 the remarks apply equally well to many other species.
