408 THE EXAMINATION OF EUCALYPTUS KINOS, 



Its composition (determined October, 1888) is: — 

 Catechin and tannic acid ... 79*22 



Ligneous matter, &c. ... ... "78 



Moisture ... ... ... ... 19-6 



Ash -4 



100-00 

 Tannic acid determination (Lowenthal) 34-032 per cent. 



Eucalyptus goniocalyx, F.v.M., B.FL iii. 229. 



Usually known as " Spotted Gum " in Victoria, but not to be 

 confused with the common N.S.W. " Spotted Gum " (E. maculata). 



No. 54. Specimen of kino from Bonang, near Delegate, where 

 the tree is known as " Mountain Gum." Height of trees, 100- 

 180 feet. Diam., 4-8 feet. Kino collected May, 1887. 



This sample is the dullest looking of all the kinos examined, 

 friability normal. It yields a brown powder. The general colour 

 of the unground portion is purplish-brown. The bulk of this 

 sample is much older than that of the sample of E. rostrata (No. 

 47), but specimens taken from bulk cannot in any way be dis- 

 tinguished from it from outward appearances. 



In cold water it forms a light reddish-brown turbid liquid, 

 leaving a muddy-looking residue of a salmon colour ; like most 

 kinos of this group, it is exceedingly tedious to extract the last 

 portions of soluble matter. 



Following is its composition (from analysis made October, 

 1888) :— 



Catechin and tannic acid ... 76*02 



Ligneous matter, <kc. ... ... 1*02 



Moisture 22-1 



Ash -86 



100-00 

 Tannic acid determination (Lowenthal) 35-555 per cent.
