The Diprotodon appears not to have been limited to any one 
portion of* Eastern Australia, for its remains have been found in 
South Australia and Queensland as far north as the York Penin- 
sula, 
In many of the “gold leads” also, fragments of bones are 
found. A section of one sample, at Wattle Flat, above the Turon 
Eiver, is given in my ])aper on “ Fossil Pones ” (Q.J.G., S. xi. 
p. 405, 1855), and in Anniversai’y Address to Itoyal Society, 
KS.W., 1870, p. 14.” 
In many ])arls of the existing region, all over the surbice, 
wherever the basal rock is not denuded, as near Sydney, there are 
local deposits which might be called “till,” were any Testacea 
found in tliem ; and in the Interior tlierc are widely spread 
accumulations of drift pebbles, which, as on the Ilunter and 
AYollondillv, arc rounded by attrition in their long journey from 
the mountains whence they have been derived. iSometimes, also, 
the Itrcaking up of conglomerates has contributed to this dritt. 
On Peak Downs tliere arc deep acenmnlations of drift, such 
as transmuted beds of the Carboniferous formation, igneous rocks, 
such as p(n'j)hyry and basalt, and fragments of the older Paheozoic 
formation, ^'lany of tliese are encrusted with tliin calcareous 
cement, which forms cups of clear calc-spar in hollows of a fine 
porphyritic grit; the same gilt occurring on the AVarrego, on the 
Ballandoon and Yarran ridges, with transmuted quartzite, also iu 
wells there and on the Darling near Fort Bourko, in which dritt 
fine gold was detedod by mo to exist on the Downs, and has 
been again reported to me from the base of Ilankiu’s Banges on 
tbc Darling Kiver, — tlto furthest known western auriferous 
locality iu New Soulli Wales. 
In 18(59 I reported the discovery of the femur of a bird at 
the depth of 188 feet, iu drill resting on granite, from a well iu 
that part of Peak Doavus (22° 40' S.) which lies between Lord’s 
Table mountain and the head of Theresa Creek, near the track 
from Clermont to Broad Sound. Compared with the bones of 
Dinornis in tlie Australian Museum, both the Curator of that 
Institution, ami myself came to the same conclusion as to its 
genus, and accordingly it was reported iu the Geolofficcd Magazine, 
as Dinornis. Professor Owen lias, however, removed it into 
another genus Dromornis considering it to have belonged to a 
Strutbioid bird. If it was such, of course (especially after the 
deep soundings between Australia and New Zealand, established 
byll.IM.S. “Challenger” in 1.874) the speculations I indulged 
on a possible former connection between those countries as 
illustrated by such a discovery are Avorth little. But if it was a 
Dro7}wrnis, then it falls in Avitii the relationship to a present bird, 
the Emu, just as tlio Kangaroos of this epoch are related iu 
structure to the gigantic Marsupials of a past age. But Mr.
