extraordinary of the King of the Two Sicilies, for the southern Italian departments. When the Austrians occupied the Marches, he retired to his estates at Filotrano, not far from Macerata, whence, from 1816 to 1819, he made excursions to Naples, Rome, and Florence. It appears that in some way he became involved in carbonarism; for in 1821, although sick, and hardly able to stand upon his feet, he had to leave the Romagna and go into exile. Immediately after his travels in the region of the Upper Mississippi, he embarked at New Orleans, in 1824, for Mexico, and traversed that country from ocean to ocean. He returned from the United States to London in 1826 or 1827. The revolution of July called him to Paris, where we soon find him in amicable epistolary relations with the Count D’Apony, the Austrian embassador, to whom, in a letter written on the 10th of August, 1830, a few days after the revolution, he offered his services towards ameliorating the condition of his native country. At the same time, he carried on a correspondence with Benjamin Constant, with Lafayette and Lafitte. He participated in the theories of the Napoleonists of his time, and aspired for the elevation of the nations, and especially for that of Italy. In 1834, the Scientific Congress at Stuttgard being in session, Beltrami was sent to it to represent the Historical Institute of France, accredited therefore by the perpetual secretary, Mons. de Monglave, who did not hesitate to style him one of the most honorable and distinguished of that scientific association. Shortly after, he went to Heidelberg, where he acquired a small landed estate which he lived on for two years. In 1837 we find him at Vienna; then, shortly, at Home, and so—now here, now there—he lived till 1850, when, finding himself bowed down by the weight of years, he returned to his property at Filotrano, where, amongst his early friends, he placidly passed the remainder of life, and where, in February, 1855, he died, having completed his seventy-fifth year. Beltrami was a man of frank and sincere soul—an enemy of all flattery, and capable of unparalleled self denial. In proof of the latter, it is related that although he suspected that the cases of articles sent by him from America had been opened and plundered on their arrival at Florence, yet, to avoid the bitterness of certainty of such fact, he would never consent to their being examined during his lifetime, desiring that it should only be done by his heirs,—as so happened. In the desire to be more generally read, he wrote everything in foreign languages, for which indeed he can hardly be blamed, having to print his works out of Italy. A complete list of his published writings is as follows: 1. _Deux mots sur des promenades de Paris et Liverpool._ Philad’a., 1823. 2. _La Decouverte des Sources du Mississippi, &c._ New Orleans, 1824.
