84 ON SOME N.S.W. TAN-SUBSTANCES. 



Kino-tannic acid — 46*95 per cent. 



Note. — Mr. Kirton states that a single tree of this species will 

 yield as much as two gallons of liquid kino. 



15. Eucalyptus macrorrhyncha, F.v.M., N.O. Myrtacese, B. Fl. 

 iii., 207. 

 Figure Dec. 1 of Baron Mueller's " Eucalyptographia." 

 Found chiefly in Victoria, but also in Southern New South 



Wales. 

 Vernacular Name — " Stringybark." The wood is used for 



fencing and wheelwrights' work locally. 

 Locality whence this particular specimen was obtained — 



Amboyne, Delegate, 22 miles from Bombala, N.S.W. 

 Geological Formation — Limestone. 

 Part of the Tree Examined — Kino. 

 Particulars of the trees whence it was obtained — Height 80' 



to 100 feet, diameter 2 to 4 feet. 

 Collected 25th May, 1887. Analysed 4th to 18th July, 1887. 



Kino of a rich ruby colour. It is readily friable, and for this 

 reason usually appears of a dull colour, unless it has been very 

 little handled. It reminds one somewhat of some specimens of 

 seed lac. It appears only to differ from E. haimastoma kino in 

 its greater friability. The samples taken for analysis have been 

 freed from woody matter, as far as possible, by hand-picking. 



Extract. — Dissolves in water at 100° C. to the extent of 97*54 

 per cent., leaving 2*46 per cent, of a dark garnet-coloured resin..* 



Kino-tannic acid — 78*72 per cent. 



16. Eucalyptus ilemastoma, Smith, var., N.O. Myrtacerc, B. Fl. 

 iii., 212. 

 Figure Decade ii., of Baron Mueller's "Eucalyptographia." 

 Found from Eastern Gippsland through Eastern New South 



Wales to the littoral portion of Central Queensland. 

 Vernacular Name — " Rough or Small-leaved Stringybark." 

 This is the variety with persistent stringy bark. It also 

 differs in the leaves and kino from the E. lLa j mastoma 

 found further north. The wood is used for slabs and 

 fencing purposes about Colombo (Candelo). 



* I am not dealing with these insoluble residues in this series of papers, 

 preferring to keep closely to my subject. I hope, however, to report on 

 these substances later on.
