Again (p. 32) : — “ If we assume as an extreme probability that tbe 
Bacclius-Marsh sandstones are representatives of the Newcastle beds, and 
both, therefore, the nearest representatives of the Talchir-Karharbari horizon, 
it would appear to me that the peculiar plant forms ( Phyllolheca , Vertebraria , 
and Glossopteris ) of the Damuda flora .... might be considered as a 
repetition, or reappearance, of these forms of the “ Newcastle beds flora.” 
The above correlation was, as is now firmly established, quite correct, 
and it was only the subsequent discovery of a peculiar conglomerate in the 
Hawkesbury beds (see under New South Wales, No. 47) which induced me 
to correlate the same with the Bacchus Marsh conglomerate and with the 
group itself, and consequently also with the Talchir-Karharbari beds (compare 
New South Wales, No. 4S). But quite recent discoveries have re-established 
my former correlations.

Mr. Oldham writes (p. 41) : — It is unfortunate for our present pur- 
poses that none of the sub-divisions of the Gondwana series in India can be 
definitely and directly correlated with any of those of the carbonaceous series 
as exhibited in the Newcastle section, where their relative position is clear 
and free from doubt. But in Victoria there are some beds containing 
Gangamopteris, known as Bacchus Marsh beds, which seem to be the equiva- 
lents of the Talchirs. .... But their palaeontology is not the only 
connection between the two, for, like the Talchirs, the Bacchus Marsh 
beds contain abundant evidence of the action of floating ice.” 
And further is said : — C{ It is impossible to account for the formation 
of such beds as these, except by the agency of floating ice in large masses, 
and as both the Talchirs and the Bacchus Marsh beds show that when they 
were deposited the climate was much more severe than that now prevalent, 
we may take this as indicating that during their deposition there was a wide- 
spread glacial epoch corresponding to that which is known to have occurred 
in post-tertiary times. This consideration, whatever weight might be attached 
to it, if stood by itself, may certainly be said to corroborate the fossil evidence, 
and we may consequently take it as certain that the Talchir and Bacchus 
Marsh beds arc the representatives of each other.” 
On page 46 Mr. Oldham writes : — “ Seeing, then, that the palaeontology 
and stratigraphy of the beds so far from contradicting the conclusion derived
