To answer the foregoing questions I cannot do better than 

 again to refer to Suess's La Face de la Terre. 



In the eastern part of New Guinea there exist old rocks much 

 folded and strongly upheaved/ which occupy the highest parts of 

 the interior, as for instance the Owen-Stanley Range, Adolf-Haven, 

 and the southern coast of the Huon Gulf. These rocks are also 

 found in the north of New Caledonia, along the northeastern coast, 

 with a direction N.2o°-55°E. 



If we leave New Guinea and pass to Australia, we see there the 

 large central upland mentioned by Suess, which is composed of 

 granite, gneiss, old schists, and a very extensive mantle of the 

 "Desert Sandstone" (pp. 243-44). It extends to the western coast 

 of Australia, where it is abruptly interrupted. In latitude 25°i5'S. 

 on this coast a Carboniferous series has been found (p. 243). 



The eastern and southeastern parts of Australia, on the other 

 hand, consist mostly of folded mountain ranges; there we find the 

 Silurian, which is represented in Cape York peninsula (longitude 

 =1= i37|°E., and latitude 35°S.), separating the gulfs of Spencer and 

 St. Vincent (p. 249). North of this latter gulf, in the Flinders 

 Range, there are outcrops of old schists and quartzites (p. 247). 

 Further east, the old rocks of the Barrier and Grey ranges seem to 

 be identical (p. 247); finally comes the great Australian Cordil- 

 leras, about which Suess writes (p. 248): "Des granites, des 

 porphyres, des terrains cristallins, siluriens et devoniens extreme- 

 ment plisses, generalement meme redresses jusqu'a la verticale, 

 constituent le noyau de la Cordillere. ... Le Carboni^ere est presque 

 horizontal." 



I draw attention to the fact that in these mountain ranges the 

 Silurian and the Devonian, although very much folded, are still 

 recognizable by their fossils. 



Let us cursorily follow Suess in his further views on the Cordil- 

 leras. With regard to Tasmania, he writes (pp. 251-52): "Du. 

 granite, des schistes cristallins et du Silurien s'y montrent redresses 

 presque verticalement, suivant une direction meridienne; le 

 Carbonifere, tant sous le facies maritime que sous le facies con- 

 tinental, recouvre en discordance ces terrains anciens." In the
