26 Dr. Fitton on the Geology of Australia. 



denominations from other parts of the world ; and the resem- 

 blance is, in some instances, very remarkable: — The sand- 

 stones of the west and north-west of New Holland are so like 

 those of the west of England, and of Wales, that the speci- 

 mens from the two countries can scarcely be distinguished 

 from each other; the arenaceous cement in the calcareous 

 breccia of the west coast is precisely the same with that of 

 Sicily ; and the jasper, calcedony, and green quartz approach- 

 ing to heliotrope, from the entrance of Prince- Regent's River, 

 resemble those of the Tyrol, both in their characters and asso- 

 ciation. — The Epidote of Port Warrender and Careening Bay, 

 affords an additional proof of the general distribution of that 

 mineral ; which, though perhaps it may not constitute large 

 masses, seems to be of more frequent occurrence as a compo- 

 nent of rocks than has hitherto been supposed *. The mineral 

 itself, both crystallized and compact, the latter in the form of 

 veins traversing sienitic rocks, occurs, in Mr. Greenough's 

 cabinet alone, — from Malvern, North Wales, Ireland, France, 

 and Upper Saxony. Mr. Kcenig has found it extensively in 

 the sienitic tract of Jersey f ; where blocks of a pudding-stone, 

 bearing some resemblance to the green breccia of Egypt, were 

 found to be composed of compact epidote, including very large 

 pebbles of a porphyritic rock, which itself contains a consider- 

 able proportion of this substance. — And Mr. Greenough has 

 recently received, among specimens sent home by Mr. J. Bur- 

 ton, junior, a mass of compact epidote, with quartz and felspar, 

 from Dokhan, in the desert between the Red Sea and the Nile. 

 When New Holland is added to these localities, it will ap- 

 pear that few minerals are more widely diffused. 



III. The unpublished sketches, by Captain King and Mr. 

 Roe, of the hills in sight during the progress of the survey of 

 the Coasts of Australia, accord in a very striking manner with 

 the geological character of the shore. Those from the east 

 coast, where the rocks are primitive, representing strongly 

 marked and irregular outlines of lofty mountains, and fre- 

 quently, in the nearer ground, masses of strata highly inclined. 

 The outlines on the contrary, on the north, north-west, and 

 western shores, are most commonly uniform, rectilinear, — the 

 summits flat, and diversified only by occasional detached and 

 conical peaks, none of which are very lofty. 



IV. No information has yet been obtained, from any of the 

 collections, respecting the diluvial deposits of Australia: a 

 class of phenomena which is of the highest interest, in an 

 island of such vast extent, so very remote in situation, and of
