eventually obtained; one was insoluble in alcohol and ether and sublimed, the 

 other was soluble in hot water, in alcohol, and in ethei . and when purified, melted 

 at r.76 C. The acids thus indicated were |>-toluic and terephthalic. 



Thr above sample bad been stored in the dark, and in < »< tober, 1919, was 

 again analysed. Scarcely any alteration had taken place in the charactei and 

 constituents of the oil during the eighteen years it had been kept, and there was 

 no increase in cineol. 60 per cent, distilled below iq<> < . 



The crude oil had sp. gr. at 15 C. = 0-9004; rotation a B -20-4°; refractive 



index at 20 = 1-4897. 

 The rectified portion ,, = 0-8648; rotation a D -- 35-6°; refractive 



index at 20 = 1-4774. 

 The cineol was determined by the resorcinol method in the rectified portion ; 

 when calculated for the crude oil, the result was 5 per cent. 



148. Eucalyptus carulea, sp. nov. 



Stunted Ironbark. 



Systematic. — Only a medium-sized tree, with a black-furrowed bark, 

 glaucous throughout, except the bark. Leaves mostly ovate-lanceolate, shortly 

 acuminate or rounded, to lanceolate, always glaucous, coriaceous, up to 4 inches 

 long; intramarginal vein not much removed from the edge, lateral veins running 

 at an angle of 45 from the mid-rib ; petioles slender, up to § inch long. Buds up 

 to six in umbel, each on a slender pedicel, the common peduncle very slender, 

 nearly 9 lines long; calyx tube tapering very gradually to the pedicel; oper- 

 culum conical, acuminate, much shorter than calyx tube. 



Fruit. Acuminate, pyriform, contracted at opening, 

 on slender pedicels ; rim truncate, slightly 

 concave, sometimes much raised towards the 

 centre, having a domed appearance and a 

 sharp-edged rim ; valves deeply inserted ; 

 up to 5 lines long and 4 lines broad. 



The nearest resemblance to these fruits amongst 

 Eucalypts arc E. melanophloia or E. Fergusoni. 



Habitat. — ■Murrumbo, New South Wales. 



REMARKS. -In the first Edition this species was placed by us as Bentham's (B. Fl. vol. iii, p. sioj

 think, to raise it to specific rank. It appears to be quiti n trii ted to the locality where it was first disco- 

 by us. as no other pei mi' us have come to hand. It is verj picturesque with its silvery leaves, gnarled branches,
