104 Sedimentary Formations 
^ A magnificent collection of the remains in the "Wellington 
Caves has been made, at the instigation of Professor Owen, at the 
cost of the New South Wales Government, with the superin¬ 
tendence of the Trustees of the Australian Museum, by one of 
them, the late Professor Thomson, and by Mr. Gerard Krefit, 
F.L.S., C.M.L.S., &c., the late Curator of that Institution. 
The Reports of these gentlemen, together with more than a 
thousand partly determined specimens, were forwarded to Pro¬ 
fessor Owen, who has expressed his acknowledgment of the 
value of this collection, “as regards novelty, instructiveness, and 
encouragement for the future, 1 ’and as an “ important element 
in working out the ancient history of the forms of animal life 
peculiar to Australia.” 
The Coodradigbee caverns will repay research hereafter. They 
have already furnished me with bones of birds, in which those 
of an Emu are prominent. 
The latter fact chimes in with the alleged Dromornis of 
Queensland. 
Professor M‘Coy has named bones of a Dingo in a cavern near 
Mount Macedon. If it be really a dog of this period in Australia, 
it is another link between the Quaternary and Recent times. 
Yicomte d’Archiac, however, doubts its antiquity: “ Bien” lie 
says, “ ne prouve quo cechicn n'ait pan etc introduit par Jen premiers 
homines qui out penpU le continent Australicn (“ Legons sitr la 
Faune Quaterniaire , Paris” 18GG, p. 271.) 
An expedition to Howe’s Island made known, in 1SG9, the 
existence of bones of birds and turtles embedded in the beach 
rock of the island. Afterwards, a collection of them was sent to 
me by Mr. Leggatt, of Fiji. I forwarded them to Professor 
Owen, who informed me that lie was unable to determine to what 
they belonged owing to their imperfect state. They undoubtedly 
belong to some period near to the present, as the rock is a coral 
limestone common to the coast of the Pacific Islands ; and that 
deposit also contains a Bulimus scarcely distinguishable from a 
living shell of the same genus off the Island, and eggs of Turtle 
also embedded as in Raine Island in the Barrier Reef. (See 
<l Traits^ Boy. Soc. JST.S.JV.” 1870, p. 37.) 
Within the last few years, the drifts of the Cudgegong and 
Macquarie Rivers have been searched for diamonds, first reported 
in 1SG0 by myself as occurring in numbers in the latter river. 
Many thousand examples have been found ; but they are chiefly 
small and of little value, though a few have been found of larger 
size and have been cut and polished. 
A few have been brought to me from other localities in New 
South Wales, and some have been found in Victoria. 
Mr. Norman Taylor examined the forms of the mineral as it 
occurs at Two Mile Flat, &c., and figured them with care. [See
