No. 4.—This material was collected at Wellington, 250 
miles west of Sydney, New South Wales, 17th March, 1903. 
583 tbs. of branchlets gave 594 ounces of oil, equal 0°6357. 
The rotation a» of the crude oil = + 28°4'; specific gravity 
at 12° OC. = 0°8659; refractive index at 19° C..= 1:4774: 
saponification number 34°58 equal to 12°1037 ester. When 
treated with alcoholic potash in the cold, with three hours 
contact, the ester value was 5°9367); with 19 hours contact 
the ester value was 8°095”. 
On redistilling, 27> came over below 161° C.; 27% between 
161—165° C.; 31% between 165 — 200° C.; 77 between 200 — 
225°O. The specific gravity at 20° C., first fraction =0°8550; 
of the second 0°8565; of the third 0°8664; of the fourth 
0°9416. The rotation ap of the first fraction = + 30°5’s

+ 32°0°. The constituents of this oil were identical with 
those of the other samples.
