2. Oil from leaves collected near Canterbury, 5th May, 1897. 
Distilled 7th May, 1897. 
Oil rather dark in colour; odour fairly pleasant; yield *75 per 
~ eent., or 100 Ibs. of leaves and branchlets gave 12 ounces of oil; 
specific gravity as obtained -9142 @ 17°C.; specific rotation [a], + 
2°18. 
On redistillation of 100 cc. the oil commenced to distil below 
168-4°C., at which temperature five per cent. had been removed. 
This contained aldehydes. [See table. ] 
Second fraction, specific gravity -9172; specific rotation + 1:9. 
Eucalyptol in the crude oil = 50-65 per cent. 
» second fraction = 67 per cent. 
These Sie were taken from a large tree. 
3. Oil from leaves collected from “suckers,” Canterbury. Col- 
lected 10th May, 1897. Distilled 12th May. Mentioned 
in this paper as “ young leaves.” 
Oil light in colour ; odour pleasant ; yield -63 per cent., or 100 
Ibs. of leaves and branchlets gave 104 ounces of oil ; specific gravity 
as obtained ‘9169 @ 17°C.; specific rotation [a], + 4°44. 
On redistillation of 100 cc., a few drops only below 161°C., 
when the thermometer slowly rose to 170-4, by which time twelve 
per cent. has distilled. [See table.] 
The residue in still was more fluid, and less dark than was 
generally the case. 
Second fraction, specific gravity -9181 ; specific rotation + 4.35° 
Eucalyptol in the crude oil =54-4 per cent. 
a 1 second fraction = 74.7 per cent. 
From the above it is seen that the young leaves give an 
excellent oil. 
4, Oil from leaves collected near Canterbury, 11th May, 1897. 
Distilled 13th May. 
Oil darker in colour than usual, tint brownish-yellow inclining 
to orange ; odour pleasant, but not so much so as the lighter oils;
