•62 INAUGURAL ADDRESS. 



1886. Jack (Geological Map) refers the series to the Trias. 



1890. Rands (Report on Tiaro District) shows that the Burrum 

 T^eds rest tin conform ably on the Gympie beds. 



1892. Jack (Geol. Queensland, p, 312) classifies them as Lower 

 Trias-Jura. 



II. IPSWICH COAL MEASURES. 



1828. Cunningham, A. (Proc. Geol. Soc, vol. ii., p. 109, 

 1834), discovers coal on the Brisbane River. 



1872. Daintree (Quart Journ. Geol. Soc , vol. xxviii., p. 283) 

 insists on the removal of the Queensland coal deposits characterised 

 by Tceniopteris to Mesozoic, and regards the Ipswich coal forma- 

 tion as the equivalent of the Carbonaceous Series of Victoria. 



Carruthers fid., p. 356; refers the plant remains to the 

 Oolitic pei'iod. 



1876. Gregory, A. C. (Report Coal Deposits, &;c.), exhaustively 

 describes the Ipswich coal fields. 



1H83. Tenison Woods (Proc. Lin. Soc , N.S.W., vol. viii.) 

 expresses his belief "' that no very clear line of separation can be 

 made between the coal beds of Newcastle and Queensland," p. 97 ; 

 *' at present the Newcastle beds are regarded as Palaeozoic, and 

 those at Ipswich as Mesozoic; I cannot find any such clearly 

 marked distinctions," p. 98 ; but, at p. 54, he refers the Ipswich 

 formation to Jurassic, and correlates therewith the " Carbonaceous 

 of Victoria and the Hawkesbury sandstone." 



1886. Jack (Geol. Map) regards the Ipswich beds as Jurassic; 



1892. And (Geol. Queensland) classes them as Upper Trias- 

 Jura. 



fej Marine Series, West Australia. 



1861. Gregory, F. T. (Quart. Journ. Geol. Soc, vol. xviii., 

 p. 475), discovers Mesozoic rocks with Ammonites, Trigonia, &c., 

 overlying Carboniferous coal measures in the basin of the Gascoyne 

 River and near Champion Bay. They are referred Avith a doubt to 

 Cretaceous. 



1862. Jukes (Man. Geol., 2nd edit., p. 593) says that the fossils 

 discovered by Gregory " seem more like those of the Oolitic series 

 than any others." 



1863. MooRE, C. (Brit. Assoc. Adv. Sc, p. 83), observes that 

 the bulk of the Mesozoic fossils are of Jurassic age. 



1870. The same author (Quart. Journ. Geol. Soc, vol. xxvi., 

 p. 226, et seq.J more fully elaborates the fossils, describing several 

 new species, and establishes a large community of species between 

 England and West Australia.
