Chair. 
E. W. Binney, F.R.S., F.G.S., said that in vols. XVI. and 
XVIII. of the Proceedings of the Society he had given 
accounts of a Eucalyptus globulus which he had planted in 
his garden near the sea at Douglas, Isle of Man. During 
the winter of 1878 and 1879 it suffered in its foliage and 
young branches to a considerable extent; but during the 
past winter, although the temperature of the month of De- 
cember, in the Isle of Man, was lower than that of the same 
month in 1878, the tree has almost escaped damage, and is 
at the present time growing vigorously and giving out a 
strong odour throughout the surrounding air. It has not 
grown much in height during the last two years, as it is 
now considerably higher than the sea wall near to which it 
grows, but it has much increased in the diameter of its 
stem. Up to this time it has shown no signs of flowering

lyptus globulus,'’ by Edward Schunck, Ph.D., F.RS. 
Whoever has seen the Eucalyptus globulus growing must 
have been struck with the peculiar glaucous appearance of 
the foliage, such as few European plants show. I thought 
it would be of interest to ascertain whether this peculiar 
appearance might be in any degree due to the state in 
which the chlorophyll exists in the leaves. A very simple 
experiment however sufiiced to prove that the peculiar ap- 
pearance referred to is owing to a covering of fatty matter, 
such as is seen on fresh plums and other fruit, which, 
though exceeding!}^ thin, is sufiicient to modify the green
