Saxony.  Mr. Koenig has found it extensively in the sienitic tract of Jersey;** 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 considerable proportion of this substance.  And Mr. Greenough has recently received, among specimens sent home by Mr. J. Burton, 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 appear that few minerals are more widely diffused.

3.  The unpublished sketches, by Captain King and Mr.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 frequently, 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.

4.  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 which the existing animals are so different from those of other parts of the globe.  It is remarkable, also, that no limestone is among the specimens from the northern and western shores, except that of the recent breccia; and although negative conclusions are hazardous, it would seem probable, from this circumstance, that limestone cannot be very abundant or conspicuous at the places visited.  No eruptive mountains, nor any traces of recent volcanic eruption, have yet been observed in any part of Australia.

5.  The recent calcareous breccia, of which a detailed description will be found in the subjoined list of specimens, is one of the most remarkable productions of New Holland:  It was found, during the expedition of Commodore Baudin, to exist throughout a space of no less than twenty-five degrees of latitude, and an equal extent of longitude, on the southern, west, and north-west coasts;* and from Mr. Brown’s specimens it appears to occur also on the shores of the Gulf of Carpentaria.  The full account which M. Peron has given of this formation, sufficiently shows its resemblance to the very recent limestone, full of marine shells, which abounds on the shores of the Mediterranean, the West India Islands, and in several other parts of the world:  And it is
