PRESIDENT’ S ADDRESS — SECTION C. 
fossil yet found in them — Gangamopteris longifolius ; and as 
Glossojpteris (another Mesozoic type in Europe) has been found 
in New South Wales and Northern Queensland distinctly associated 
with Palaeozoic Carboniferous fossils, it may not be asking too much 
to suspend judgment in this case a little longer. 
“To those who take an interest in working out this matter, I 
would indicate, as worthy of further attention, those mud pebble-beds, 
on the Lerderberg River, immediately below where the river leaves 
the ranges. Here I have found a few pebbles grooved in the manner I 
have read of as caused bg glacial action — [the italics are mine — 
T.W.E.D.] — and here, I believe, fossil organisms will reward the 
explorer.” 
These discoveries by Daintree and Wilkinson are recapitulated 
by Mr. A. R. C. SelvvynA 
\_Op. cit p. 14.] — “ Other smaller patches [of Upper Palaeozoic 
rocks— T.W.E.D.] occur throughout the intervening central portion of 
the colony — at Bacchus Marsh and Balian, on the eastern part of the 
Mount Macedon Ranges ; on the Coliban, nearKyneton ; on the Wild 
Duck Creek, near Heathcote,” Ac. 
[Op. cit., p. 15.] — “In several of the localities above enumerated 
thick masses of conglomerate are associated with the sandstone. They 
occur generally towards the base of the series, and are composed of 
a very irregular aggregation of rounded pebbles, and occasionally 
angular or subangular fragments of all sizes of granite, greenstone, 
or diorite, various porphyries, hard slate, gritty sandstone, grey 
quartz rock, and quartz. These pebbles or fragments are imbedded 
either in a soft, sometimes earthy, mass, showing little or no trace of 
stratification, as at Darley, near Bacchus Marsh ; or are interspersed 
in a thinly stratified sandy shale, as at the point where the road from 
Sandhurst to Lanccfield crosses the Wild Duck Creek. They more 
commonly occur in hard cemented masses, as on the Mount Macedon 
4 conglomerate range.’ * * * § * * * The character of the 
conglomerate beds before-mentioned near Darley, and on the Wild 
Duck, is such as almost to preclude the supposition of their being 
due to purely aqueous transport and deposition. It is, however, 
very suggestive of the results likely to be produced by marine glacial 
transport ; and the mixture of coarse and fine, angular, and waterworn 
material, much of which has clearly been derived from distant sources, 
would also favour this supposition. 
44 Grooved or ice-scratched pebbles or rock fragments have, how- 
ever, not yet been found. 
In 1877 Professor Tate made the important discovery of the 
glaciated pavement and glacial beds at Hallett’s Cove, and on 7th 
May of that year he announced his discovery in a course of public 
lectures, J and in 1879 he read a paper on the same subject. §
