The Oil from the Fruits. 



The fruits of this species were received from Shuttleton, December, 1903. 

 No leaves were present. The distillation was continued for seven hours, and 71 lb. 

 of fruit gave 5 oz. of oil, equal to 0-44 per cent. The crude oil had a more tur- 

 pentine-like odour than the leaf oil, and was dark coloured, it was thus necessary 

 to remove the colour with dilute soda to enable the rotation to be taken. 



The saponification number for the free acids as thus determined was o-8. 



The specific gravity of the crude oil at "ff° C. = o-86o8; rotation, a„ 

 = + 0-3°; refractive index at 19° C. = 1-4738. The saponification number of the 

 cleared oil was 5-1, equal to 1-78 per cent, ester. The crude oil did not deposit 

 resin on the bottle, thus differing again in this respect from the leaf oil.

The timber is pale coloured, straight-grained, having a density and texture 

 similar to the other jjale-colourcd woods of the genus. It is easy to work and is 

 used for house buihiing, esj)ecially where the white-ant is found, and in this con- 

 nection it will no doubt be es]iecially useful for railway sleepers in those parts of 

 the country infested with these destructive insects. It is, therefore, worthy of 

 conservation in the arid interior. It could be used for ddors, panelling, wains- 

 coting, &c.
