ON SOME N.S.W. IAN-SUBSTANCES. 85 



Locality whence this particular specimen was obtained — 



Colombo, near Canclelo, N.S.W. 

 Geological Formation — Granite. 

 Part of the Tree Examined — Kino. 

 Particulars of the trees whence it was obtained — Height 40 



to 60 feet, diameter 2 feet. 

 Collected 24th December, 1886. Analysed 4th to 15th July, 



1887. 



This kino is of a rich ruby colour. When freshly exuded it is 

 of a clear light ruby colour, becoming more or less opaque, and of 

 a Vandyke-brown colour, if it remains sufficiently long on the 

 trees. It is clean to handle, powders fairly readily, forming a 

 light purplish-brown powder. The resemblance to the kino of 

 E. macrorrhyncha is most marked when they are both in powder. 

 This kino has been freed, as far as possible, from woody fibre by 

 hand-picking. 



Extract. — 95*53 per cent, of this kino is soluble in water at 

 100° C, leaving 4*47 per cent, of residue, chiefly consisting of a 

 dark coloured resinous substance. 



Kino-tannic acid — 54*12 per cent.* 



17. Eucalyptus rostrata, Schlecht.,TX.O, Myrtacea?, B. Fl. iii., 240. 

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

 . Found in all the Colonies. 

 Vernacular Name — "Red Gum," (the "Bed Gum" par 



excellence, and so called from the colour of the wood). 

 Locality whence these particular specimens were obtained — 



Colombo, near Candelo, N.S.W. 

 Geological Formation — Granite. 

 Part of the Tree Examined — Insect galls from saplings, 



causing the abortion of leaf-buds and flower-buds. None 



of these are the ordinary leaf-galls, in which cases the 



leaf-tissue is more or less developed. 

 Collected 28th June, 1887. Analysed 13th to 23rd July, 1887. 



These galls are more or less perforate, the perfect insect having 

 in most cases taken its departure. They are all more or less 

 weather-worn and pulverulent. The colour is from yellowish to a 

 dirty yellowish- brown. Average diameter about \ inch. Owing 



* In the Catalogue of Queensland Woods Exhibited at the Colonial and 

 Indian Exhibition, 1886, this kino is said to yield 64*51 per cent, of tannin 

 but no particulars in regard to it are given.
