Chief among petrographical features are the occurrences of two mineral inter- 
growths, viz., a granophyrie one of pleonaste and diopside, and a graphic inter- 
growth of augite and picotite. 
2. Mr. R. H. Cambage, F.L.S., read a paper on Acacia Seedlings, Part VL., 
in which the seedlings of seven Acacia species are described. 
He stated that one seed pod of Acacia Farnesiana had floated in sea water 
for over eleven weeks, and another for over twelve weeks; and, as he had pre- 
viously demonstrated that a seed of that species would germinate after having 
been immersed in sea water for three and three-quarter years, he considered the 
likelihood .of the distribution of this species being sometimes effected by ocean 
currents was strengthened. The twinning of seedlings of Acacia asparagoides 
was recorded, several seeds having produced twin plants. ; 
3. On a Box Tree from New South Wales and Queensland,” by J. 7. 
Maiden, F.R.S. 
This tree, which is described as a new species, seems to deserve the name 
of “ Narrow-leaved Box” better than all the boxes, its juvenile leaves being 
narrow-lanceolate, and its mature foliage almost as narrow. ‘The fruits are 
small, and timber pale brown. It is one of the trees known as “ Mallee Box.” 
It differs from Hucalyptus bicolor, which has narrow juvenile foliage, in the 
red timber and thick bark of the latter, and is widely different from JF. 
Woollsiana, R. 'T, Baker, which has broad juvenile foliage. It has been collected 
from Gilgandra, New South Wales, to Southern Queensland, and it is par- 
ticularly abundant in the Pilliga scrub. The type comes from Narrabri, New 
South Wales.
