On redistilling the crude oil, the results below were obtained. Th<

rhe crude oil had specific gravity al 15 C. 0-889; rotation a -12-2°; 

 refractive index a1 20° 1 -4838, and was soluble in 1 volume 80 per cent, alcohol. 

 The saponification number for the esters and free acid was 9-1.

The presence oi aromadendral is well demonstrated by the rotation oi the 

 crude oil to the left being higher than that of the first fraction. Although light 

 did not pass well with the second fraction, yet it was highly laevo-rotatory. 



In order to test the constancy of the oil products from this species, three 

 other consignments were received from various localities in the Girilambone 

 district, and one from Condobolin, also in N.S.W. The oils were all in agreement, 

 as can be seen from the tabulated results. They all formed clear solutions with 

 1 volume 80 per cent, alcohol.

 White Box. 



Systematic. Generally a liner tree than its congener E. hemiphloia, 

 F.v.M. The hark- oi both are very similar, being white, but not deeply 

 furrowed. It occurs generally mi higher ground than the "Box" E. hemiphloia, 

 F.v.M. , and the timber is considered the better oi the two. Leaves lanceolate, 

 falcate, long and broad, coriaceous, glaucous; the venation is generally pro-
