416 THE EXAMINATION OF EUCALYPTUS KINOS, 



Eucalyptus eximia, Schauer, B.F1. iii. 258. 



No. 64. " Mountain or Yellow Blood wood." The Valley, near 

 Spring wood, N.S.W. ; collected April, 1888. Height of tree, 

 70-80 feet ; diam., 1-2 feet. 



This kino is bright looking, much resembling the better samples 

 of E. corymbosa kino, but the colour of the powder at once dis- 

 tinguishes it from that kino, the powder of E. eximia being of a 

 dark buff colour, slightly darker than the majority of kinos of 

 this group. The soft friable nature of the bark of this tree makes 

 the collection of the kino a matter of difficulty, and it appears 

 never to exude abundantly. In water it does not wholly dissolve ; 

 the liquid on standing becomes quite clear and transparent and of 

 an amber colour. 



It was analysed August, 1891, with the following result : — 



Catechin and tannic acid ... 8441 



Ligneous matter, <fcc. ... ... 3'2 



Moisture 11-99 



Ash -4 



100-00 

 Tannic acid determination (Lowenthal), 47-5 per cent. 



Eucalyptus clavigera, A. Cunn., B.F1. iii. 250. 



No. 65. Kino received November, 1889, from Baron von 

 Mueller, who obtained it from Arnhem's Land, North Australia. 



Bright looking, deep reddish- brown in colour. Friability and 

 colour of powder normal. 



In water it does not wholly dissolve, the catechin remaining as 

 a yellow powder. On standing, the water becomes clear and 

 transparent and of a bright amber colour. 



Following is the analysis (made August, 1891) of this kino : —
