414 THE EXAMINATION OF EUCALYPTUS KINOS, 



remainder of the liquid is of an amber colour * sediment of a very 

 dark red, and powdery. Alcohol yields a very bright red liquid. 



It was analysed October, 1888, with the following result : — 

 Catechin and tannic acid ... 68*42 



Ligneous matter, &c. ... ... 16*38 



Moisture ... ... ... ... 14*7 



Ash *5 



100-00 

 Tannic acid determination (Lowenthal) 45-714 per cent. 



No. 61. The Valley, Springwood, Blue Mountains, N.S.W. 

 2nd April, 1888. Diam., 1 foot. Height, 50 feet. 



This sample was also obtained from the concentric layers of a 

 tree. When removed it was slightly plastic, and of a dark crimson 

 colour, reminding one strikingly of a candied fruit jam. When 

 fresh (and for some weeks afterwards) it had a vinous odour. 



It behaves to cold water in the same manner as the preceding 

 specimen, except that the colour is much brighter looking. Alcohol 

 yields a very bright red liquid. 



It was analysed October, 1888, with the following result : — 

 Catechin and tannic acid ... 63-18 



Ligneous matter, &c. ... ... 20*12 



Moisture ... ... ... ... 16*3 



Ash *4 



100*00 

 Tannic acid determination (Lowenthal) 36*053 per cent. 

 No. 62. The Valley, Blue Mountains, 3rd April, 1888. 



This kino was an outward exudation. It is rich coloured, and 

 so excessively brittle that the vessel containing it readily becomes 

 coated with a fine powder. In large masses it is of a purplish-red 

 colour, while the powder inclines strongly to Indian-red. The 

 colour of this kino when freshly exuded had all the brilliancy 

 already described, but it tones down somewhat on keeping.
