North-east coast of Australia.) The second instance is taken from Mr.Cunningham's manuscripts and is contained in the following extract:* The south and south-eastern extremes of Clack's Island presented a steep, rocky bluff, thinly covered with small trees.

I ascended the steep head, which rose to an elevation of a hundred and eighty feet above the sea.
The remarkable structure of the geological features of this islet led me to examine the south-east part, which was the most exposed to the weather, and where the disposition of the strata was of course more plainly developed.

The base is a coarse, granular, siliceous sandstone, in which large pebbles of quartz and jasper are imbedded: this stratum continues for sixteen to twenty feet above the water: for the next ten feet there is a horizontal stratum of black schistose rock which was of so soft a consistence that the weather had excavated several tiers of galleries; upon the roof and sides of which some curious drawings were observed, which deserve to be particularly described.

They were executed on a ground of red ochre (rubbed on the black schistus) and were delineated by dots of a white argillaceous earth, which had been worked up into a paste.

They represented tolerable figures of sharks, porpoises, turtles, lizards (of which I saw several small ones among the rocks) trepang, starfish, clubs, canoes, water gourds, and some quadrupeds, which were probably intended to represent kangaroos and dogs.
