618 ON KINGS AS AN AID IN THE DIAGNOSIS OF EUCALYPTS. 



A rather handsome Kino. Freshly exuded, of a pale ruby 

 colour ] a portion of it is in very thin fragments, and shows a 

 colour like orange lac. Much of it has been allowed to flow into 

 a vessel and therefore is nearly pure. 



Cold water yields a very pale ruby solution with a tint of rose. 

 Colour of residue brown. 



Kino-tannic acid, 67-52 per cent. ; insoluble phlobaphenes^ 4 

 per cent. ; soluble in cold water, 95*4 per cent. 



Eucalyptus Sieberiana, F.v.M. (Syn. E. virgata, Sieb., the 



species name in B.Fl. iii. 202). 



Found in S. Australia, Tasmania, Victoria, and N. S. AVales. 



22. " Mountain Ash." I have obtained a sample of Kino from 

 this species (Mt. Victoria, N.S.W., March, 1889), which is an 

 ordinary ruby Kino, both in appearance and chemical deport- 

 ment. 



23. " Mountain Ash," " Black Ash." A second sample of 

 Kino of this species is from Tantawanglo Mountain, near 

 Candelo, N.S.W., and is from a tree 60-80 ft.; diam., 2-6 ft. It 

 was collected 12th July, 1889. It has exuded for a much longer 

 time than the preceding sample. Neither has been quantita- 

 tively analysed. 



Eucalyptus stellulata, Sieh., B.Fl. iii. 200. 

 Found in Victoria and N. S. Wales. 



24. "Sally or Black Gum." Bombala, KS.W., 17th Feb., 

 1887. Height, 30-50 ft.; diam., 2 ft. 



A ruby Kino similar to most of the others in general appear- 

 ance. 



It yields a medium ruby liquid, with some phlobaphene residue 

 and a few particles of woody matter. Colour of residue purplish- 

 brown 



Kino-tannic acid, 61*97 per cent.; insoluble phlobaphenes, 7.2 

 per cent.; soluble in cold water, 9242 per cent.
