a in the crude oil = 64°5 per cent. 
» second fraction = 78-4 per cent. 
This is an excellent oil, and was from young trees from twenty 
to thirty feet in height. 
7. Oil from leaves collected near Canterbury, 13th May, 1897. 
: Distilled 17th May. 
Oil rather dark coloured, odour pleasant ; yield °734 per cent., 
or 100 ibs. leaves with branchlets gave 113 ounces of oil ; specific 
gravity as obtained = ‘9166 @ 17° C.; specific rotation [a], + 0°54. 
On redistillation of 100 cc. below 168-4° C. three per cent. had 
been obtained, this was removed. It contained aldehydes. [See 
table. | 
Second fraction, specific gravity ‘9185; specific rotation + ‘87. 
Eucalyptol in the crude oil = 58-4 per cent. 
» second fraction = 75:5 per cent. 
Mixed sites from fair sized trees. 
8. Oil from leaves collected near Canterbury, 8th June, 1897. 
Distilled 9th June. 
Oil almost colourless ; odour quite pleasant ; yield -66 per cent., 
or 100 tbs. of leaves and branchlets gave 104 ounces of oil.; 
specific gravity as obtained ‘9164 @ 15°C.; specific rotation 
[a], + 0°66 
On redistillation of 100 cc. only two or three drops came over 
below 165-2°C., the mercury then rose rapidly to 167° C. [See 
table. | 
First fraction, specific gravity = ‘9072; specific rotation + 1-71, 
Second = ‘916 ee + 0-982. 
acalyptel i in the crude oil = 56°6 per cent. 
», second fraction = 67:2 per cent. 
These fia were taken from a fair sized tree. The rotation 
of the terpenes in the first fraction is small. 
9. Oil from leaves collected near Canterbury, 8th June, 1897. 
Distilled 10th June. 
Oil rather dark in colour, in fact the darkest of the whole of 
the specimens; yield -72 per cent., or 100 Ibs. of leaves an
