" The Ojster Bay Pine of Tasmania." Found in all the 

 colonies except Western Australia (normal species). 



This is the pine already referred to, and a brief account of 

 the resin has been copied into many of the text-books. I 

 have collected resin of this species from Port Jackson, clear 

 and transparent as water. It turns pale amber coloured in 

 12 months if placed in a bottle, but its brilliancy shows no 

 sign of diminution in that time. The Sydney trees readily 

 exude their resin on slightly wounding, and the same remarks 

 apply to the Tasmanian. 



CALLITRIS CALCAEATA. B. Br.

Found from Northern Victoria to Central Queensland. 

 " Murray Pine," "Black Pine," Red Pine," " Scrub Pine," 

 " Cypress Pine." 



8ample 1. " Murray Pine," Quiedong, 3rd March, 1887. 

 Has a pale, bleached appearance, much lighter than ordinary 

 Sandarach. Externally it has a very mealy appearance. 

 Water has no effect on it. In rectified spirit it almost wholly 

 dissolves, leaving a little whitish, resinoid substance. 

 Petroleum spirit dissolves 5 per cent, of a perfectly colourless 

 and transparent resin. 



Sainple 2. I have received a quantity of flesh-coloured 

 resin from the Snowy River, N.S.W., belonging to this 

 species. It is so different in appearance from the normal 

 resin, that no market can at present be found for it, and as 

 this is the first time such resin, in quantity, has come under 

 my notice, it is well worth describing. It is of the consistence 

 and general appearance of Manila elemi, differing from that 

 substance in being of a flesh-colour, and having a pure 

 turpentine odour, instead of a turpeutiue-fennel one. 



There is no doubt that it would form a valuable ingredient 

 in plasters, and an enterprising pharmacist would doubtless 

 find it worth his while to follow the matter up. 



It is a remarkable circumstance that the trees yielding this 

 resin had also, at other portions of the stem, more or less of 

 the normal Sandarach. 



Sample 3. " Red Pine." Lachlan River, N.S.W. Feb. 1885. 

 This has comparatively freshly exuded, and has the colour 

 and appearance of the best selected Sandarach. 



Rectified spirit nearly wholly dissolves it, forming a 

 beautifully clear, slightly yellowish liquid; 1*3 percent, of
