conclusions with regard to the sequence of the Tertiary Strata of 
Victoria, which are at variance with the classification adopted by the 
Geological Survey.* * * § 
Mr. A. W. Howitt records the interesting discovery by himself that 
the igneous dykes at the 180 mine at Bendigo, Victoria, are composed 
of the ultra- basic lava, limburgite.t 
In New South Wales the discovery by Mr. W. J. Clunies Boss, and 
also by Mr. E. E. Pittman, the Government Geologist, and. myself, of 
Lepidodendron associated with a fauna of Upper Devonian affinities, 
has been referred to bv me elsewhere. J 
Mr. B. Dunstan has discovered iti a bed of clay shale belonging 
to the llawkesbury series, and therefore of Triassic age, at Curl Curl 
Lagoon, Manly, near Sydney, several fossil ferns which Mr. E. 
Etheridge, junr., identifies as Oleandridium . This is the first record, 
as far as I am aware, of the occurrence of this genus in Australia. § 
A useful petrological paper on the basalts of Bondi, near Sydney, 
has been contributed by the Kev. Milne Curran. || 
In Tasmania the discovery by Mr. E. J. Dunn of Pliocene or 
Post-Pliocene morainic deposits, and of glacial beds : perhaps of Permo- 
Carboniferous age, near Mount Zeehan, will be referred to later. 
The Government Geologist, Mr. A. C. Montgomery, by his 
vigorous and outspoken reports upou the Mount Huxley mine, has not 
only won a reputation for himself by the courage and ability he dis- 
played, but has given an excellent practical demonstration as to the 
usefulness to the State of such an officer on such an occasion. 
III. — EVIDENCES OF GLACIAL ACTION IN AUSTRALIA AND 
TASMANIA. 
(I.) Previous Observations. 
One of the first, if not the first, to note glacial action in Tasmania 
was, perhaps, Mr. Charles Gould, the former Government Geologist. 
The statement is made, on the authority of Mr. B. M. Johnston, 
that, as far back as about 1853, Mr. Gould observed evidences of 
glaciation in Tasmania, and communicated his views to the Hon. Jas. 
Beid Scott, formerly Chief Secretary of Tasmania. The latter about 
twenty-one years ago made known the results of Mr. Gould’s observa- 
tions to Mr. Johnston. Unfortunately Mr. Gould did not publish 
any account of his discoveries. 
The first actual record of ice-action in Australia is that made in 
1859 by Mr. (now Sir) Alfred B. C. Selwyn.** The passage reads as 
follows : — “ At one point in the bed of the Inman I observed a smooth,
