422 THE EXAMINATION OF EUCALYPTUS KINOS, 



No. 71. Kino from Nowra, gathered March, 1888. Height, 

 60-80 feet. Diam., 1-2 feet. 



The trees yielding this sample had been recently ringbarked, 

 and bush fires had recently passed through the locality. The 

 flow of kino was copious. This sample is exceedingly like No. 

 69 as far as outward appearance goes, though its odour is as 

 powerful as No. 67. 



It is the most readily soluble in cold water of all the samples 

 of this species examined, nevertheless it behaves much in the 

 same way as No. 67. Water at 100° C (1 grm. to 1 litre) yields a 

 perfectly clear bright amber-coloured liquid. Alcohol yields an 

 olive-brown liquid. 



It was analysed August, 1891, with the following result : —

Eucalyptus microcorys, F.v.M., B.F1. iii. 212. 



No. 72. "The Tallow-wood" of New South Wales, called 

 " Turpentine " in Queensland, but not to be confused with the 

 New South Wales Turpentine ( Syncarjria). Sample of kino from 

 New England, N.S.W., received 1886. 



Kino of this species is less vesicular than that of E. maculata, 

 but almost as readily reducible to a powder. This particular 

 specimen is in small pieces, for the most part of the size of currants. 

 In bulk it looks remarkably like a parcel of uncut garnets. Owing 

 to its friability, the bright fractures become dulled with very little 

 friction. Colour of powder orange-brown. 



To cold water a yellow solution is yielded, with a slight tinge 

 of brown, having a turbid residue of a dirty yellow colour with a
