home with him valuable speciemns notably a fine series of American fossils from the James Hall in the sixties. The colletion of Cycadoe is said to be the finest in Europe. There are not a few unique specimens in this museum, and when the late King Humbert received as a gift a fien Glyptodor he immediately inquired of Capellini if he desired it in the museum at Bologna where it is now preserved. Therefore in the interest of Science it would seem that the Italian cast of the Diplodocus should be erected in the greatest of Italian museums of natural history, which without question that of Bologna. But it might be well to place a model in Rome, and I have no question that the gelogists throughout the world, if not the Italian geologists alone, would be subscribe the necessary sume to defray the expense of such an installation. Professor Capellini, under date of August 14, asks me to say that it is quite the same to hime whether you address him in English or Italian. He mentions the circumstances, known to us all, that the king's permission is always obtained before any gift or any kind is offered, adding that for half a century this permission has been accorded to him by the House of Savory. He is in constant communication with the royal family, which will visit Spezia in a few days when he will take the opportunity of conferring with the King in reference to this affair, and telegraph me the result of his interview. He remarks that Bologna has always been the Sceince-capital of Italy; writes the proverb 'Bononia docet,' and hence the international congress of prehistoric studies of 1871, and the international congress of geologists of 1881 were held there. In rome the study of geology has never thriven, and hardly anything of consequence illustrating that Science exists there.
