PROTOZOIC ROCKS OF THE NORTH OF W.A.

I he Protozoic Rocks of the North of Western 
Australia. Bi Dudwig Glauert, F.G.S. (RGa.fl March 
1 2 th , if) 12.) Communicated by permission of the Director 
of the W.A. Museum. B. H. Woodward Esq. 
I propose this evening to confine mv remarks to the 
northern portion of the Continent— (i) to the North West 
of the Northern Territory, where the researches of Messrs. 
H. J L. Brown and H. Basedow have yielded facts and 
conclusions which will enable ns to unravel some of the 
problems of Western Australian geology ; and (2) to the 
Kimbei ley district, where the late E. T. Hardman discovered 
Jossils which, unknown to him and probably quite un- 
expected by him, furnish the first palaeontological proof of 
I lotozoic or Older Palaeozoic Sediments in Northern and 
Western Australia. 
Owing to the inaccurate reading of Hardman’s labels 
the localisation seemed to be so vague as to render scientific 
use of the discovery hazardous in the extreme. 
In * 9°6 Mr. R. Etheridge writes in N.T. of S.A. North- 
'd cst District, Geological Reports resulting from the ex 
Isolations made by the Government Geologist and staff 
during 1905, on page 42, when referring to Hardman’s 
fossils, that: — 
“ Unfortunately the .... specimens were verv pourly localised and 
1 nave quite failed to identify his precise locality.” 
And at a later date (1907) Mr. A. Gibb Maitland 
sums up the situation in the following terms (G S W A 
Bulletin 26, page 48) 
r u' 1 ^ >es P' t f 1 he fact of the poor localisation of Hardman’s fossils, it may, 
I think, be taken for granted that Cambrian beds do occur somewhere in 
Kimberley about South latitude i8 D .” 
A few months ago I decided to investigate the matter, 
with a view of attempting to solve the problem. I carefully 
examined a number of reports and documents dealing with 
these Cambrian fossils, and in a Contribution to the. Records 
ol the W.A. Museum, now in the Press, have determined the 
exact position of three localities where Hardman collected 
Olenellus I’orresti and Salterella Hardnumi. 
Although I am not permitted to enter into the matter 
at the present juncture, I may say that inaccuracies in the 
first published descriptions as they appear in the Geol. 
Mag. Decade III, Vol. VII (1890) are responsible for the 
confusion that has arisen. And out of fairness to the late 
E. T. Hardman, I must add that as far as I am able to 
judge Hardman’s localisations are sufficiently accurate to 
guide subsequent investigators to the outcrops which 
yielded the Olenellus and the Salterella in 1884.
