410 THE EXAMINATION OF EUCALYPTUS KINOS, 



was as fluid as molasses at first, but on a few moments' exposure 

 to the air it hardened, and became quite brittle. 



In cold water the bottom layer of liquid is of a rich reddish- 

 brown, the rest of the liquid becoming, by diffusion, of the colour 

 of olive oil. Abundant sediment. 



Following is the composition of this kino (analyses made 

 October, 1888). 



Catechin and tannic acid ... ... 81*3 



Ligneous matter, &c. ... ... '9 



Moisture 17-6 



Ash -2 



100-00 

 Tannic acid determination (Lowenthal) 31-99 per cent. 

 No. 57. Cambewarra (Bangley Creek), 21st and 27th April, 

 1888. Height, 50-60 feet. Diam., 2-3 feet. 



The collector of this specimen said, " the kino of this Eucalypt 

 is very rare, and very seldom shows 'itself outside on the tree ; it 

 usually collects in blisters under the bark, and those blisters are 

 mostly on the branches or high up on the stem." My own 

 experience is that, while this is not a plentiful kino, one 

 occasionally comes upon masses containing several pounds, by 

 following a fissure in the bark, near the ground. The present 

 sample has evidently remained long on the trees, and is therefore 

 of a dull colour for the most part, but individual pieces are 

 exactly described by the description already given of the 

 preceding specimen. 



No. 58. Bangley Creek, Cambewarra, May and June, 1888. 

 The descriptioD of No. 57 will apply here.

Ligneous matter, &c. ... ... *4 



Moisture 17*5 



Ash -3 



100-00 

 Tannic acid determination (Lowenthal) 34-031 per cent.
