Since this paper has been at the press, a Report presented to the Academy of Sciences at Paris, on the Voyage of Discovery of M. Duperrey, performed during the years 1822 to 1825, has been published; from whence I have subjoined an extract, in order to complete the catalogue of the rocks of Australia, according to the present state of our information.

Les echantillons recueillis tant dans les contrees voisines du Port Jackson, que dans les Montagnes-Bleues, augmentent beaucoup nos connoissances sur ces parties de la Nouvelle Hollande.  Les echantillons, au nombre de soixante-dix, nous offrent, 1.  Les granites, les syenites-quartziferes, et les pegmatites (granites graphiques) qui cunstituent le second plan des Muntagnes-Bleues. 2.  Les gres ferrugineux, et renfermant d’abondantes paillettes de fer oligiste, qui couvrent non seulement une vaste etendue de pays pres des cotes, mais encore le premier plan des Montagnes-Bleues; et 3.  Le lignite stratiforme qu’on exploite au Mont-Yorck, a 1000 pieds au-dessus du niveau de la mer, et dont la presence ajoute aux motifs qui portent a penser que les gres ferrugineux de ces contrees appartiennent au systeme des terrains tertiaires.

Vingt-sept echantillons ramasses a la terre de Van Diemen, dans les environs du port Dalrymple, et pres du Cap Barren, indiquent, 1.  Des terrains de pegmatite, et de serpentine. 2.  Des terrains intermediaires coquilliers, formes du grauwacke-schistoide, et de pierre calcaire. 3.  Des terrains tres-recens, composes d’argile sablonneuse et ferrugineuse, avec geodes de fer hydrate, et du bois fossile, a differens etats.  On distingue en outre des belles topazes blanches ou bleuatres, parmi les galets quartzeux, qui ont ete recueillis au Cap Barren:  Bulletin des Sciences Naturelles, Octobre 1825 page 189.)

2.  The specimens of Captain King’s and Mr. Brown’s collections, without any exception, agree with those of the same denominations from other parts of the world; and the resemblance is, in some instances, very remarkable:  The sandstones of the west and north-west of New Holland are so like those of the west of England, and of Wales, that the specimens 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, chalcedony, and green quartz approaching to heliotrope, from the entrance of Prince Regent’s River, resemble those of the Tyrol, both in their characters and association.  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 component 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
