ignore tlic evidence which contradicts their own preconceived 
opinions. It will have been seen in the preceding remarks, that I 
have myself suggested the possibility of some part of our Sedi¬ 
mentary deposits having a relation to the Trias, and it is only 
fair to state that Professor M‘Coy, in his earlier writings, limited 
the New South Wales deposits to the Oolite of Scarborough. 
Afterwards the term “ Mesozoic” was introduced to define the 
period — which, of course, left all undefined from the base of the 
Tcrtiaries to that of the Trias ; the limit of range allotted by him 
for the Queensland Secondary Marine fossils and plants being 
from the “ lower part of the great Oolite” to il the base of the 
Trias” (“Annals” ix,No. 50,Feby., 1862), placing all on one geo¬ 
logical platform. He might, therefore, admit the Trias to repre¬ 
sent the “ Mesozoic” instead of the Oolite, but he has stuck 
firmly to the latter. 
On the other hand, I presumed to think that the plant-beds in 
the separate Colonies did not represent the Oolite — and that for 
reasons assigned I have ventured to believe that the Coal-beds 
belong to some part of the Upper Palaeozoic, either represented 
by visible examples elsewhere, or belonging to strata not yet 
found elsewhere represented. 
In working out my own conclusions, I had recourse to what 
was reported by the Geological Survey of India; and relying on 
the data proclaimed, I held that the nearest ally to our Coal-beds 
was the Damuda division of what is now known as the u Gond- 
wana series or system” of Feistmantel, (“Records ” No. 2, 1876, 
page 28.) Dr. Oldham agreed with me, as has been seen ; but 
Dr. Feistmantel having obtained or discovered the existence of 
plants in beds not previously recognized by the Survey, e.g. 
Glossoptens , — and finding it not only in the Damuda, but in the 
Talchir strata below, and also in all the intermediate strata, 
through the Panchet up to the Bajmahal and Cutch (Dr. Old¬ 
ham agreeing with him as to Panchet being Triassic),—has come 
to the following arrangement: — 
Jurassic 
Trias ... 
( Oolite ( 1.—Cutch or Each with Jubalpur. 
( Lias \ 2. — Eajmahal (in different places). 
Mveuper (3.—Panchet (in different places). 
| 4.—Damuda (do., including the Bani- 
-j ganj (Kamthi), Iron-Shale, and 
| Barakar groups). 
I Gres Bigarre ( 5. — Talchir. 
These are the “ five horizons ” of the Gondwana system. 
If this arrangement be correct, then it is clear that there is a 
a Triassic series amidst the beds which M‘Coy held to be alto¬ 
gether Oolitic, but which I, in common with Dr. Oldham, con¬ 
sidered in part Palaeozoic; and here I may quote Mr. W. T.
