Qualitative Tests — (Dilute extract). 



1. Distinctly acid reaction. 



2. Equal volume of sulphuric acid (1 in 5). In the cold, dense 



salmon ppt. On boiling, clear ruby liquid. 



3. Bromine Water — Light brown ppt, with streaks or coagulated 



masses of a bright yellow colour which rise to the top of the 

 liquid like a scum. 



4. Dilute ferric chloride— Deep purple colour. Neither this nor

ppt. 



8. Tartar Emetic — Pink gelatinous ppt. Add Ammonium 



Chloride — The ppt condensed. 



9. Copper sulphate — Slight turbidity. Add Ammonia — Dense 



dirty olive-green ppt.

 white glazed tile). Orange-brown colour, with slight tinge 

 of magenta.

 Eucalyptus Siebeejana,(F.v.M.), N.O. Myrtacese,(i?.mr</aia,Sieb.,isthe 



species name in B. Fl. iii., 202, vide also Dec. 2, F.v.M., " Eucalypto- 



graphia/') " Cabbage Gum/' is the name by which this tree is 



known in the Braidwood district of N.S.W., owing to the perishable 



nature of the wood. The wood of Victorian trees appears to be more 



durable. Called also " Mountain Ash/' " Gum Top/" &c. 



Found — In all the Colonies except Queensland and Western Australia. 



Locality of the particular specimen now under examination : — 



Monga, near Braidwood, N.S.W. 



Remarks — The bark of the trunk. Diameter of stem 3 feet from the 



ground, 1 foot to 2 feet. Height, 60 to 80 feet. Date of 



Collection, 1st and 2nd Oct., 1886. Date of Analysis, 20th April, 



17th and 21st May, 1887.

examination readily becoming dulled by a coating of their own
