On rectification, 2 per cent, distilled below 169 C. (corr.). This portion 

 contained a predominance of volatile aldehydes, the odour of which was objec- 

 tionable. Between 169-183, 80 per cent, distilled; between 183-224, g per 

 cent, came over, and between 224-255, 3 per cent, distilled. These fractions 

 gave the following results : 



First fraction, sp. gr. at 15 C. 0-8947; rotation D + 5-5. 



Second ,, ,, =0-9172; -2-7. 



Third ,, ,, = 0-9390; ,, not taken. 



The cineol, determined by the phosphoric acid method in the first fraction, 

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



This sample of oil had been kept in the dark, and in October, 1919, 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 fraction gave the 

 following results : 



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



at 20 : 1-4734- 

 Large fraction ,, ,, = 0-9007; rotation a D '+ 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 39 per cent., when calculated for the crude oil. 



Ill, Eucalyptus DeaneL 



(J.H.M., in Proc. Linn. Soc., 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 fine, numerous, at an angle of 45 

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

 umbels of about six flowers. Calyx tube conical, ij 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; i\ 

 lines long, and 2 lines in diameter. 



It approaches perhaps E. saligna in shape, more than 

 that of any other species. 



Habitat. Eastern New South Wales into Queensland. 







REMARKS. This is a species by no means easy to separate from E. saligna either in the field or by 

 herbarium material. The young state leaves, however, are broader than in that species.
