98 Sedimentary Formations 
may discover fresh deposits of Tertiary age, hut so far as 
examination of the collections in my possession from Capo 
York, New Guinea, Brighton Cliffs, Elemington, &c., may serve 
as a guide, there is no proof of anything further than a resem¬ 
blance in the colour and composition of the ferruginous sand¬ 
stones of the Victorian localities to justify the supposition at 
present. 
Dr. Eattray (Q.J.G.S., xxv. 207), in his 11 Notes on the 
Geology of Cape York Peninsula ” (read 2nd May, 1809), says 
distinctly: “No fossils have been detected ’ in the sandstone 
“between the volcanic rock beneath and the superimposed Post- 
tertiarv ironstone,” in the bold cliffs of Albany Island and the 
opposite mainland. He mentions also that the Jardines, in 
their traverse of the Peninsula, found the same rock at various 
parts of their route ; but he says also, that at the north end of 
Albany Island, where a boss of porphyry protrudes and dis¬ 
places the overlying sandstone and ironstone, line examples of 
chertified clay, ironstone, and quartzite may be seen at their 
point of contact ” (p. 302.) 
Now, Mr. Wilkinson gives a list of rock specimens as follows: 
1. Quartz porphyry (Palaeozoic) (?) from Cape York, found 
underlying beds of Tertiary (?) ferruginous sandstone. 
2. Vesicular basalt and brecciated volcanic tufa (Upper 
Tertiary), from Darnley Island. 
3. Small concretions of limonite, with polished looking sur¬ 
faces, dredged up off the Coast of New G uinea. 
4. Specimens of Chalcedony and flint, from Kail's Sound. 
5. Oolite limestone (Tertiary), very friable, from Bramble 
Bay. 
(I Yellow calcareous (Tertiary), from Katau Eiver. 
7. Yellow and blue calcareous (Tertiary), from Yule 
Island and Hall’s Sound. 
Whether No. 4 has any relation to the “chertified clay 
ironstone ” of Eattray I know not, hut it is certain that there 
are many instances to be found in New Guinea of highly altered 
strata. No. 3 is also a common variety of iron ore in many 
places besides thoso indicated, e.g., at New Harbour, 100 
feet above the sea, where the nodules of iron have the exact 
kind of polish mentioned in No. 3, and are of considerable size. 
[Similar nodules, but of red species, occur also at Port Essing- 
ton, on the opposite horn, so to speak, of the Gulf of Carpen¬ 
taria.] 
Although I do not go fully into particulars respecting evi¬ 
dence in my own possession concerning the Tertiary beds in the 
localities already mentioned, yet I may state that the calcareous 
rock of light colour occurs on various points between the coast
