The Mii.nl. determined b\ the resorcinol method in the portion boili 

 below r.90 C, and calculated for the crude oil, was 50-3 pej cent. 



When it was found thai the estei in the oil oi this spi 1 ii - was .1 low I oiling 

 one it was decided to reverl to the original oil from the lasmanian ti 

 fortunately the fractions had been preserved fne sa ation number 



for the esters in the firsl fraction was 1.5*8, so thai here again the greatei 

 portion of the esters was the low-boiling one, and from the odoui and other 1 

 was evidently butyl-butyrate, as in the oil from the New South Wales material

Systematic. A small tree, reaching a height of 20 to 30 feet, with a rough 

 hark. Leaves lanceolate to broad lanceolate, acuminate, often uncinate thick, 

 coriaceous and shining, usually under 5 inches long; venation very indistinct, 

 except in the young foliage, when the vascular bundles are marked by grooves 

 on the leaf surface intramarginal vein removed from the edge, lateral veins 

 more or less spreading, inclined at about 30° to the mid-rib. Peduncles 

 axillary or lateral, flattened, about q lines Ion- each bearing an umbel of 

 three to seven flowers. Buds shining, with seven to ten ridges, shortly pedicellate : 

 calyx tube urn- or bell-shaped, 4 to 5 bur- long; operculum 4 lino long, at first 

 domed and slightly greater in diameter than the calyx, in some cases the uppet 

 half abruptly contracted into a. narrow ;one. 



Fruit.— Truncate-ovoid, inclined to be urn shaped, 

 more or less longitudinally ribbed, shining; 

 rim convex, the periphery concave .hie to 

 1 he prominent groove; valves net ex- 

 serted; from 5 to 10 lines long and 4 to 7 

 lines in diameter at the widest part. 



A very characteristic fruit and one which lias little
