My bed-room window opens upon the court in the interior of the hotel Rivoli, in which I lodge. In looking out occasionally upon my very near neighbors opposite, I have frequently observed a gray-headed, scholar-like, fine-looking old man, writing at a window in the story below. One does not trouble himself much about his fellow-lodgers, and I had seen this gentleman at his work at all hours, for a month or more, without curiosity enough to inquire even his name. This morning the servant came in, with a _Mon Dieu!_ and said _M. Sismondi_ was frightened by the cholera, and was leaving his lodgings at that moment. The name startled me, and making some inquiries, I found that my gray-headed neighbor was no other than the celebrated historian of Italian literature, and that I had been living under the same roof with him for weeks, and watching him at his classical labors, without being at all aware of the honor of his neighborhood. He is a kind, benevolent-looking man, of about sixty, I should think; and always had a peculiarly affectionate manner to his wife, who, I am told by the valet, is an Englishwoman. I regretted exceedingly the opportunity I had lost of knowing him, for there are few writers of whom one retains a more friendly and agreeable remembrance. In a conversation with Mr. Cooper, the other day he was remarking of how little consequence any one individual found himself in Paris, even the most distinguished. We were walking in the Tuileries, and the remark was elicited by my pointing out to him one or two celebrated persons, whose names are sufficiently known, but who walk the public promenades, quite unnoticed and unrecognised. He said he did not think there were five people in Paris who knew him at sight, though his works were advertised in all the bookstores, and he had lived in Paris one or two years, and walked there constantly. This was putting a strong case, for the French idolize Cooper; and the peculiarly translateable character of his works makes them read even better in a good translation than in the original. It is so all over the continent, I am told. The Germans, Italians, and Spaniards, prefer Cooper to Scott; and it is easily accounted for when one remembers how much of the beauty of the Waverly novels depends on their exquisite style, and how peculiarly Cooper's excellence lies in his accurate, definite, tangible descriptions. There is not a more admired author in Europe than Cooper, it is very certain; and I am daily asked whether he is in America at present--so little do the people of these crowded cities interest themselves about that which is immediately at their elbows.
