404 THB EXAMINATION OF EUCALYPTUS KINOS, 



Only obtainable in rather small quantities, and in rather small 

 pieces. Pale, as kinos go, very bright-looking, and of a ruby 

 colour. Powders fairly readily, forming a powder of a light 

 brown tint. 



It dissolves almost immediately to a pale brownish or almost 

 orange solution, leaving a sediment of a whitish-salmon colour, 

 with a few dark-coloured particles, like those of E. goniocalyx, 

 only cleaner looking. 



Its composition (determined October, 1888) is : — 

 Catechin and tannic acid ... 82*7 



Ligneous matter, &c. ... ... *6 



Moisture ... ... ... ... 15-8 



Ash -9

 Tannic acid determination (Lowenthal) 47*746 per cent. 



Eucalyptus viminalis, Labill. (Syn. E. fabrorum, Schlecht.), 

 B.F1. iii. 239. 



Dr. Wiesner says of two samples of kino belonging to this 

 species : — " E. viminalis. Only partly soluble in water, with 

 light brown colour; contains a little gum-resin. Brittle, like 

 kino. Add hydrochloric acid to the solution, then ammonia, a 

 precipitate is obtained which blackens in the air." 



" E. fabrorum., not readily soluble in water : solution yellowish, 

 faintly acid, turbid on cooling; contains gum-resin. Particles 

 dark black-red, slightly transparent shiny fracture." 



The following statement occurs in the Report Intercol. Exhib., 

 Melbourne, 1861 : — "The resin (sic) of E. viminalis in its decom- 

 posed state furnishes a real pigment." 



No. 48. "Ribbony Gum," "Manna Gum." This is a variety with 

 bluish, broad leaves. Quiedong, near N.S.W. : Victorian border, 

 26th March, 1887. Height, 60-80 feet. Diam., 3-4 feet. 



In small fragments, prevailing colour reddish-brown of all 

 depths of tint. Bright-looking. Easily reducible to a powder 

 between the fingers. Colour of powder light orange-brown.
