Staiger (Queensland Cat. Col. and Ind. Exh., 1886) says of a 

 sample of this kino, " 59-03 insoluble in water, 10-82 soluble in 

 alcohol, leaving 48-21 per cent., which "was mostly soluble in 

 caustic soda. This insoluble substance was intensely black, and 

 was partly derived from altered kino-tannin, and partly from 

 other substances not yet thoroughly investigated." 



Dr. Bancroft observes that, owing to the ready friability of this 

 kino, it is very suitable for powders and pills. It is given in 

 doses from 2 to 10 grains. 



Dr. Wiesner (loc. cit.) says, "Of all samples received most 

 readily soluble in water. Solution deep blood -red ; smells dis- 

 tinctly like Bordeaux wine, slightly acid, turbid on cooling, free 

 from gum-resin. Bright shining surface of fresh fracture of 

 lumps. Colour deep red." 



No. 60. Cambewarra, August, 1886. Diam., 3-4 feet. Height, 

 80-100 feet. 



This sample is in irregular pieces as large as the fist. Before 

 they have been bruised they have the appearance of a very 

 pulverulent, purplish-red hsematite (such, for instance, as is com- 

 mon in the Elba mines). To say that it resembles a low-grade 

 dragon's blood also gives a very good idea of its appearance. It 

 readily makes an impalpable powder of a Venetian red colour, 

 soiling everything with which it comes into contact. 



Bloodwood kino can be delivered in Sydney for about 3d. per 

 lb., and there is no doubt that it is a cheap and efficient substitute 

 for the lower grades of dragon's blood. Both the aqueous and 

 alcoholic solutions (especially the latter) form good wood-stains. 

 Experts will probably pronounce the colour to be too fiery, but it 

 can be brought to the required tint by admixture with burnt 

 sienna or vandyke brown. 



This specimen was from a very old tree, and one nearly dead. 

 It was not obtained by wounding the stem, but was found caked 

 in large masses between the trunk and the bark. 



With cold water it forms a rich garnet-col ou reel liquid at the 

 bottom of the vessel if undisturbed. As diffusion proceeds, the
