ANNIVERSARY ADDRESS OF THE PRESIDENT. x¢cvil 
seams and beds of coal, varying in thickness, and which form a 
ortion of the adjacent main land of Borneo, extending to, and more 
inland than the town of Brunai. The most considerable bed yet no- 
ticed is up a stream named the Kiangi, tributary to the Brunai river, 
and not far from the town, where it occurs eleven feet thick, and 
in a highly inclined position. Close to it is another bed three feet 
thick. From the statements of Mr. Hiram Williams, who was sent 
by the Admiralty to examine this coal district in 1845, it has evi- 
dently been much disturbed and contorted. Its relations to other 
accumulations (limestones, igneous rocks and others) in this part of 
Borneo, is as yet not clearly determined, but subsequently to its 
contortion this coal-bearmg deposit has been subjected to denuding 
action, and the edges of the beds left are covered by others containing 
shells similar to those in the adjacent seas. The coal beds vary much 
in composition, as may be seen by the following analyses, made for the 
Admiralty at the Laboratory of the Museum of Practical Geology.

It should be observed that several hundred tons of the Labuan 
coal have been raised, and that the bed is now worked. The steam- 
ers which have used this coal, though it more approaches the cha- 
racter of candle or cannel coal, than the ordinary bituminous varieties, 
report well of it. 
GEOLOGICAL SOCIETY OF FRANCE. 
Although it would too far extend the limits of this Address to de- 
tail the labours of the Foreign Societies which more or less devote 
their attention to geology, we must not omit a brief notice of so much 
of the proceedings durmg 1847, as have already reached us, of the 
Geological Society of France; since, though so named, its members 
are not confined to one country, the Society, without any distinction 
as to foreign members, being open to all fittmg persons, wheresoever 
they may have been born, or now dwell. 
In a communication on the variations of the igneous rocks, M. Du- 
rocher points out many examples of change, such as the passage of 
greenstone (diorite) ito diallage rock and serpentine in the Cotes-du- 
* With respect to this analysis it should be stated, that the specimen was from 
the crop of the bed, long exposed to the sea, and therefore that it is scarcely a 
fair example of the component parts of the coal deeper beneath the surface, and 
in a more favourable situation.
