32°2°; of the second + 31°7; of the third + 30°6°; of the 
fourth + 32°5°. The constituents were identical with those 
in the other samples. 
No. 6.—This material was collected near Tamworth, 280 
miles North of Sydney, New South Wales, 3rd March, 1908. 
388 Ibs. of branchlets, containing some fruits, gave 35 ounces 
of oil, equal to 0°563%. Specific gravity, crude oil at 24° C. 
= 0°8665; rotation dp = + 25°2°; refractive index at 24° C. 
= 1°472; saponification number 40°2, equal to 14°07% ester. 
These results are practically identical with those obtained 
with the other samples, and it was thus thought unneces- 
sary to carry the investigation further.

No. 7.—This material was collected at Nyngan, 380 miles 
west of Sydney, New South Wales, 29th December, 1899. 
358 tbs. branchlets gave 303 ounces of oil, equal to 0°532". 
The distillation was continued for eight hours, but very 
little oil came over during the extra two hours; it was 
sufficient, however, to increase the specific gravity some- 
what, although the ester content was but little improved. 
The specific gravity at 24° C. = 0°8782; rotation ap = + 
22°7°; refractive index at 19° C. = 1°4774; saponification 
number 40°61 equal to 14°21 ester.
