Botanical Gardens, growing on the Clarence River. On com 
paring the living leaves with the impressions in the various 
deposits mentioned, I can see me identity. This is a point in 
Geology not yet fully dealt wi 
The most remarkable sentatace I have met with is on the 
coast, about forty-two miles north of Cape Howe, where, at a 
place’ called Chouta (between Tura and Boonda) a cliff about 
100 feet high, formed of sand and white silicate of alumina, 
contains beds of lignite charged with sulphid of iron, and 
which are full of phytolites much allied to the living vegetation. 
From the clays, some of which are nearly kaolin, articles of 
pottery have been formed, which, with the clays and sands, are 
exhibited. (See Nos. 269 & 371) It has been proved that, 
by distillation, a fair proportion of lubricating oil may be pro- 
duced from the lignitiferous clay, and other products are “ax 
pected to result from these deposits. The cliffis about 60 fee 
thick from the sea to the top of the clays, and borings te 
the sea level have shown a still greater thickness. 
These deposits lie between the horns of the little bay at Tura 
and Boonda, resting at one end on the highly undulating 
tan rocks, and at the other on a mass of Porphyry. 
, formerly, no doubt, deposited in a depression among 
the “ope of the hills , but the wearing away of the coast has 
left a cliff of clay and sand instead of the srapitiid cliff of hard 
rocks. It is remarkable that, at the south end the rocks as- 
sume the character of a breccia of quartz, cemented by siliceous 
matter (probably like a deposit mentioned by Mr. Gould as 
occurring in Tasmania) and in it analysis has detected the
