INAUGURAL ADDRESS. 55 



Palaeozoic age, at least of these genera which had been so 

 strenuously questioned by several writers. 



1866. Clarke (Quart. Journ. Geol. Soc, vol. xxii., p. 439) 

 classified the coal measures and associated strata as follows: — 



Hawkesbury Series. 



Upper Coal Measures. 



Upper Marine Beds. 



Lower Coal Measures. 



Lower Marine Beds (with Palseozoic plants). 



1867. Keene (Intercol. Exh. Essays, p. 396) holds that the 

 Lower Coal Measures are older than any in Europe, and that the 

 opinions " that the lowest intercalate with Silurian fossils and a 

 Devonian flora are untenable." 



1876 McCoy limits the term Carboniferous to the beds in New 

 South Wales which are below those with Glossopteris, and to the 

 Lepidudendron beds underlying the Lower Marine Series (Geol, 

 Surv., Victoria, Report iii., pp. 57-59). 



Clarke attributed a Silurian age to the slates and quartzites 

 which cross into Queensland at the heads of the Severn River. 

 These are referred by Jack to the Gympie Series (Geol. and Pal., 

 Queensland, p. 74, 1892). 



1878. Clarke (Remarks Sed. Formations, p. 66) removed the 

 Hawkesbury Series from the Carboniferous, 



1880. Wilkinson (Dep. Mines for 1879, p. 216) applied the 

 term Permian to the Upper Coal Measures, and that of Carboni- 

 ferous to the subordinate beds. 



1881. Feistmantel (Foss. Flora, Gondwana Syst., vol. iii.) 

 regards the Newcastle beds as Lower Trias. 



1383. Tenison Woods (P.L.S., N.S.W., vol. viii. pp. 52-53) 

 refers the Lepidodendron beds, in part, to Lower Carboniferous, 

 whilst the Glossopteris beds are referred — the lower portion to 

 Permian (?) and the upper to Trias. (?). 



1887. Feistmantel (Sitz. K. Bohm. Ges. der Wissen.) classified 

 the Carboniferous Series of New South Wales as follows : — 



(^Newcastle beds or Upper Coal
