ON SOME N S.W. TAN-SUBSTANCES. 193 



Vernacular Names — " Messmate," " Narrow or Almond- 



leaved Stringybark." 

 Locality whence this particular specimen was obtained — 



Broom an, Clyde River. 

 Geological Formation — Granite. 

 Part of the Tree Examined — Kino. 

 Particulars of the trees whence it was obtained — Height 100 



to 120 feet, diameter 2 to 3 feet. 

 Collected 14th and 15th September, 1886. Analysed 12th to 

 22nd September, 1887. 

 This tree much resembles E. obliqua (the ordinary Stringybark), 

 but the leaves of the former are narrower, the bark rougher and 

 not so fibrous as that of E. obliqua ; it is also much richer in kino. 

 This substance is used by some of the local settlers in the 

 manufacture of ink, the process simply consisting in boiling it in 

 an iron vessel ; the liquid is also used for staining leather black. 

 This kino is obtained in pieces larger than is usual in the case of 

 clear kinos, some of the pieces being as large as a walnut. It is 

 of rather a dark colour, and rather hard and tough, but breaking 

 down into garnet-coloured fragments. Has a very bright fracture. 

 Extract. — Yields 99*75 per cent, to water at 100° C. Colour 

 of liquid bright garnet or ruby. Residue same as E. stellulata, 

 but with a very small amount of woody fibre. 

 Kino-taunic acid — 62'12 per cent.

Found from Southern New South Wales to Southern 



Queensland. 

 Vernacular Name — " Ironbark." 

 Locality whence this particular specimen was obtained — - 



Cambewarra. 

 Geological Formation — Sandstone. 

 Part of the Tree Examined — Bark. 

 Particulars of the trees whence it was obtained — -A sapling 



about 6 inches in diameter. 



Collected 21st August, 1886. Analysed 12th to 22nd 



September, 1887. 



It will be interesting to compare this analysis with that of the 



E. siderophloia bark described above (page 39). " Botany Bay 



Kino/' was chiefly obtained from this species, hence the name A. 



resinifera, A. Cunn. (non Smith). This tree yields the chief 



portion of Ironbark timber in New South Wales. This bark
