192 ON SOME N.S.W. TAX-SUBSTANCES. 



This tree yields excellent tire-wood ; otherwise it is considered 

 of little use. It does not often attain a height of more than 12 

 feet at Nangutta. It yields kino in considerable quantity. The 

 kino is in pieces intermediate in size between that yielded by E. 

 amygdalina var. and E. piperita var. (referred to in this paper) 

 but presenting no marked differences from those kinos. It is hard 

 to powder, being very tough. The colour of its powder is near 

 Venetian Red. 



Extract. — Yields 99*22 per cent, to water at 100° C. Solution 

 of a moderately intense ruby colour. Residue, a black resinous 

 substance intermixed with woody fibre of a brown colour. 



Kino-tannic acid — 62*96 per cent.

iii., 202. Figure Decade " Eucalyptographia " (Mueller). 

 Found in Victoria and New South Wales (range not 



co-extensive with that of the normal species). 

 Vernacular Name — " Peppermint." 

 Locality whence this particular specimen was obtained — - 



Rombala. 

 Geological Formation — Limestone. 

 Part of the Tree Examined — Kino. 

 Particulars of the trees whence it was obtained — Height 60 



to 80 feet, diameter 3 feet. 

 Collected 14th to 16th February, 1887. Analysed 12th to 26th 



September, 1887. 



Of all shades of ruby or garnet, clear, more friable than the kino 

 of E. piperita, but forming a less bright powder. Colour of powder 

 light Indian red. Dr. Wiesner loc. cit. (E. maeulata) speaks of 

 this kino becoming turbid from solution in water. I cannot 

 confirm this observation. 



Extract. — Yields 06.06 percent, to water at 100° C. Solution 

 of about the same colour, and nearly as intense as E. piperita. 

 Residue consists of a black resinous substance intermixed with 

 woody fibre of a brown colour. 



Kino-tannic acid — 5 8 "41 pf r cent.
