B. Silliman on Wollongongite. 7 85 
Art.. X.—Note on Wollongongite, a remarkable hydro-carbon 
found in the Wollongong District of the Illawarra Coal Field, 
N.S. Wales ; by B. Sitti ayn. 
In the course of a research conducted by Prof. Wurtz and 
myself, lately, on the Hydro-carbon Gas Process, my attention 
was recalled to a peculiar kind of cannel coal from Australia 
which was brought to this country in 1866, by Mr. Hall of 
Australia, from whom I obtained my first ‘knowledge of its 
existence. As it turns out on examination to be by far the 
most remarkable substance of its class hitherto discovered I 
propose to describe it. 
It is found in the Wollongong district of the Hlawarra Coal 
Field, New South Wales, and in the range known as the Kem- 
bla Mountains, or Blue Mountain range. The loeality appears 
to be of recent discovery, as the section taken down from Mr. 
Hall’s dictation is quite different from any section given by 
Prof. Dana in his account of the Illawarra coal field.* Mr. 
Hall’s enumeration of the strata was as follows.
