It was analysed 1st June, 1892. 



Determination of tannic acid by Lowenthal's metliod, 47-5 

 per cent. 



This kino belongs to my " Turbid (Iroup ; " and contains a 

 medium amount of catechin. 



RESINS. 

 Callitris verrucosa, R. Br. 



N.O. Coniferce: "Pine." 



Sample 1. — Collected on sand-hills at various places in the 

 Victoria Desert. No date. Collector's note : — " This is the 

 resin of tree with cones like enclosed, and different to earlier 

 collected specimens." 



A transparent colourless resin, having externally the powdery 

 appearance characteristic of resins of this genus. It is entirely 

 soluble in alcohol, and readily powders. Its composition and 

 appearance in no way differ from that of the sandarach of com- 

 merce, for which it is a perfect substitute. For further informa- 

 tion in regard to our indigenous CaUitris-resms, see my paper, 

 entitled "Australian and Tasmanian Sandarach" (Proc. Roy. Soc, 

 Tasmania, 1889). The following additional note in regard to 

 this species may be given : — " The resin of C. verrucosa was used 

 to make firm the union (after lashing) of the hard-wood head to 

 the reed, in the making of reed-spears by the aboriginals of Vic- 

 toria. The resin was called by them bij-jin-ne." ("Aboriginals 

 of Victoria," Brough Smyth, I., 306). 



Sample 2. — Collected 3rd July, 1891, amongst granite rocks at 

 Camp 14. Collector's note: — "Up to 30 feet, diameter 1.5 in. at 

 base, but i-unning up very conical. From trees and ground. The 

 resin runs." 



Hardly differs in appearance and behaviour from the preceding 

 sample. 



XANTHORRiiajA Prkissii, Endl. (probably). 

 N.O. Liliacece : "Grass-tree " — " Gnora " of tlie natives. 



Collected 18th September, 1891, at Camp 55, Victoria Desert. 

 Notes by collector : — " Sand hills. The trees had been burnt, 

 and large masses of the gum were collected around the base witli 

 sand blown in wliile in the semi-liquid state. Some were near 15 

 feet high, and 18 inches in diameter." 



This resin is in largish pieces of a dark purple-brown colour ; it 

 is very impure from the admixture of sand and vegetable debris. 



Alcohol dissolves out 36 per cent, of a dark, rich-coloured 

 resin, having much the appearance and behaviour of tliat derived 

 from X. arborea under similar treatment.
