428 SIR RODERICK I. MURCHISON'S ADDRESS— EUROPE. [May 25,1857. 



environs of Rome, nearly upon the same scale^ajs the French Survey, 

 upon which will be laid down the principal estates of the great 

 landowners ; and M. Rosa, a very laborious topographer, who has 

 already surveyed in great detail many of the most interesting 

 districts around the Eternal City, has just completed a very beau- 

 tiful map of the Alban hills, on the eve of publication by the Roman 

 Topographical Office (Za Direzzione del Censo). 



In the posthumous work of the late eminent Antiquary, Architect, 

 and Topographer, Commander Canina, are contained several maps 

 and plans of considerable interest in a geographical point of view, 

 amongst which the revised edition of his great map, in six sheets, 

 of the Campagna of Rome, of the Upper Valley of the Anio, with 

 detailed plans of the most remarkable ancient towns and classical 

 sites of the Alban Lakes, and the ancient ports of Centumcellae, 

 Portus Trajani, Ostia, Antium, &c. &c. Connected with our pur- 

 suits may be mentioned the detailed statistics of the Roman States^ 

 (Statistica della Popolazione dello Stato Pontijicd), just published by the 

 Papal Government. 



Naples. — I am not aware that any progress has been made by the 

 Government of this country in the great Survey of the kingdom, 

 inaugurated by our late Associate, General Visconti. 



The French Depot de la Marine, having obtained the consent of 

 the King of Naples to prolong its hydrographic survey of the West 

 Coasts of Italy, beyond the Neapolitan frontier, M. Darondeau has 

 been able, during the past year, to complete it as far south, and 

 including the Bay of Naples, the Ponza Islands, &c. This, with 

 the survey of the Roman Coast, is terminated, as my friend 

 Mr. Pcntland tells me, and will form a worthy complement to the 

 great survey of the coasts of Italy, commenced in 1841, and which 

 extends from the mouth of the Var to the Island of Capri. M. 

 Darondeau is now engaged in rectifying the charts of the Lipari 

 Islands, in the position of some of which errors of importance have 

 recently been pointed out. 



Island of Sardinia. — General A. della Marmora has completed his 

 labours on the Physical Geography and Geology of this interesting 

 island, by publishing the last volume of his great work, containing 

 geology and descriptions of the fossils, by the eminent palaeontologist, 

 Professor Meneghini, of Pisa. As General Alberto della Marmora 

 (brother of the Sardinian commander-in-chief in the Crimea) has 

 devoted the best years of his life to the accomplishment of this ar-
