 contained .1 predominance oi volatile aldehydes, the odour "I which was objec- 

 tionable. Between [6g [83 , 80 per cent, distilled; between 183 224°, g pei

The cineol, determined by the phosphoric ai id method in the first fraction, 

 indicated 32 per cent, in the crude oil O.M.). 



This sample ol oil had been kept in the dark, and in October, tgig, nineteen 

 years afterwards, was again analysed. The oil had not altered much during 

 that time, as shown by the following. 92 per cent, distilled below 190° C, 

 commencing to distil at 167°. The crude oil and the large traction gave the 

 following results : — 



Crude oil, sp. gr. at 15 C. = 0-9114; rotation a D + 5-0 ; refractive index 



.11 20 = 1-4734. 

 Large fraction ,, ,, = 0-9007; rotation «„ + 5-5° ; refractive index 



at 20° — 1-4709. 



The cineol was determined by the resorcinol method in the large fraction, 

 and calculated for the crude oil; the result was 48 per cent. By the phosphoric 

 acid method it was ;<) per cent., when calculated for the crude oil. 



Ill, Eucalyptus Deaneu 



(J.H.M., in Proc. I. inn. Sue, N.S.W., 1904, p. 471.) 



Systematic. —A very large tree, with a smooth bark, ribbony at the base, 

 having extensive buttresses. Abnormal leaves ovate, sometimes orbicular, more 

 or less acuminate, petiolate, thin. Normal leaves lanceolate to broad lanceolate, 

 very acuminate, mostly under 6 inches long; venation fairly distinct, intra- 

 marginal vein close to the edge, lateral veins line, numerous, at an angle of 45 

 to the mid-rib. Peduncles axillary or lateral, angular, 2 to 5 lines long, bearing 

 umbels of about >i.\ flowers. Calyx tube conical, ii lines long, tapering to a 

 pedicel of about equal length; operculum inclined to hemispherical, umbonate. 



Fruit.— Slightly hemispherical to bell-shaped, pedi- 

 cellate ; rim thin, somewhat convex or even 



countersunk; valves just exserted; _'', 

 lines long, and 2 lines in diameter.
