June 1824.

I am informed that Mr.Von Buch also has published a paper on the rocks of New Holland; but have not been so fortunate as to meet with it.
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.
