EUCAL YPTUS. 165 



EUCALYPTUS CORYNOCALYX. 



It does not entirely dissolve in cold water; the super- 

 natant liquid is pale yellowish, and it does not entirely 

 dissolve in alcohol ; the liquid becomes clear on standing, 

 but on agitation has a very turbid appearance. Its compo- 

 sition (determined August, 1891) is: 



Catechin and tannic acid 82.473 



Ligneous matter, etc 3.827 



Moisture 13 .370 



Ash 332

Tannic acid determination (Loweuthal), 26.2 per cent. 



EUCALYPTUS LEUCOXYLON. 



Behaviour and appearance in water similar to Euca- 

 lyptus corynocalyx sample. In alcohol it does not entirely 

 dissolve; the supernatant liquid is bright, clear, and of a 

 reddish-brown color; the liquid is very turbid when agi- 

 tated. Its composition (determined August, 1891) is: 



Catechin and tannic acid 79 .279 



Ligneous matter, etc 4.9 



Moisture 14-95 



Ash 871

Tannic acid determination (Lowenthal) 21.5 per cent. 



EUCALYPTUS ROSTRATA. 



The well known "Red Gum" of Victoria and the Mur- 

 ray and Edwards Rivers, N. S. W. 



The kino of this species is perhaps the best known of 

 all Eucalyptus kinos, chiefly through the enterprise of Mr. 

 Joseph Bosisto, of Melbourne. 



It is a useful astringent, and it seems to be increasing 

 in favor with medical men in England, America and 

 Australia.
