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.

LETTER XX.

GENERAL BERTRAND—FRIEND OF LADY MORGAN—PHRENOLOGY—DR. SPURZHEIM—HIS LODGINGS—PROCESS OF TAKING A CAST OF THE HEAD—INCARCERATION OF DR. BOWRING AND DE POTTER—DAVID THE SCULPTOR—VISIT OF DR. SPURZHEIM TO THE UNITED STATES.

My room-mate called a day or two since on General Bertrand, and yesterday he returned the visit, and spent an hour at our lodgings. He talked of Napoleon with difficulty, and became very much affected when my friend made some inquiries about the safety of the body at St. Helena. The inquiry was suggested by some notice we had seen in the papers of an attempt to rob the tomb of Washington. The General said that the vault was fifteen feet deep, and covered by a slab that could not be moved without machinery. He told us that Madame Bertrand had many mementoes of the Emperor, which she would be happy to show us, and we promised to visit him.

At a party, a night or two since, I fell into conversation with an English lady, who had lived several years in Dublin, and was an intimate friend of Lady Morgan. She was an uncommonly fine woman, both in appearance and conversational powers, and told me many anecdotes of the authoress, defending her from all the charges usually made against her, except that of vanity, which she allowed. I received, on the whole, the impression that Lady Morgan's goodness of heart was more than an offset to her certainly very innocent weaknesses. My companion was much amused at an American's asking after the "fender in Kildare street;" though she half withdrew her cordiality when I told her I knew the countryman of mine who wrote the account of Lady Morgan, of which she complains so bitterly in the "Book of the Boudoir." It was this lady with whom the fair authoress "dined in the Chaussée d'Antin," so much to her satisfaction.

While we were conversing, the lady's husband came up, and finding that I was an American, made some inquiries about the progress of phrenology on the other side of the water. Like most enthusiasts in the science, his own head was a remarkably beautiful one; and I soon found that he was the bosom friend of Dr. Spurzheim, to whom he offered to introduce me. We made an engagement for the next day, and the party separated.

My new acquaintance called on me the next morning, according to appointment, and we went together to Dr. Spurzheim's residence. The passage at the entrance was lined with cases, in which stood plaster casts of the heads of distinguished men, orators, poets, musicians—each class on its particular shelf—making altogether a most ghastly company. The doctor received my companion with great cordiality, addressing him in French, and changing to very good German-English when he made any observation to me. He is a tall, large-boned man, and resembles Harding, the American artist, very strikingly. His head is finely marked; his features are bold, with rather a German look; and his voice is particularly winning, and changes its modulations, in argument, from the deep, earnest tone of a man, to an almost child-like softness. The conversation soon turned upon America, and the doctor expressed, in ardent terms, his desire to visit the United States, and said he had thought of accomplishing it the coming summer. He spoke of Dr. Channing—said he had read all his works with avidity and delight, and considered him one of the clearest and most expansive minds of the age. If Dr. Channing had not strong developments of the organs of ideality and benevolence, he said, he should doubt his theory more than he had ever found reason to. He knew Webster and Professor Silliman by reputation, and seemed to be familiar with our country, as few men in Europe are. One naturally, on meeting a distinguished phrenologist, wishes to have his own developments pronounced upon; but I had been warned by my friend that Dr. Spurzheim refused such examinations as a general principle, not wishing to deceive people, and unwilling to run the risk of offending them. After a half hour's conversation, however, he came across the room, and putting his hands under my thick masses of hair, felt my head closely all over, and mentioned at once a quality, which, right or wrong, has given a tendency to all my pursuits in life. As he knew absolutely nothing of me, and the gentleman who introduced me knew no more, I was a little startled. The doctor then requested me to submit to the operation of having a cast taken of my head, an offer which was too kind and particular to be declined; and, appointing an hour to be at his rooms the following day, we left him.

I was there again at twelve, the morning after, and found De Potter (the Belgian patriot) and Dr. Bowring, with the phrenologist, waiting to undergo the same operation. The preparations looked very formidable, A frame, of the length of the human body, lay in the middle of the room, with a wooden bowl to receive the head, a mattress, and a long white dress to prevent stain to the clothes. As I was the youngest, I took my turn first. It was very like a preparation for being beheaded. My neck was bared, my hair cut, and the long white dress put on. The back of the head is taken first; and, as I was only immersed up to the ears in the liquid plaster, this was not very alarming. The second part, however, demanded more patience. My head was put once more into the stiffened mould of the first half, and as soon as I could get my features composed I was ordered to shut my eyes; my hair was oiled and laid smooth, and the liquid plaster poured slowly over my mouth, eyes, and forehead, till I was cased completely in a stiffening mask. The material was then poured on thickly, till the mask was two or three inches thick, and the voices of those standing over me were scarcely audible. I breathed pretty freely through the orifices at my nose; but the dangerous experiment of Mademoiselle Sontag, who was nearly smothered in the same operation, came across my mind rather vividly; and it seemed to me that the doctor handled the plaster quite too ungingerly, when he came to mould about my nostrils. After a half hour's imprisonment, the plaster became sufficiently hardened, and the thread which was laid upon my face was drawn through, dividing the mask into two parts. It was then gradually removed, pulling very tenaciously upon my eyelashes and eyebrows, and leaving all the cavities of my face filled with particles of lime. The process is a tribute to vanity, which one would not be willing to pay very often.

I looked on at Dr. Bowring's incarceration with no great feeling of relief. It is rather worse to see than to experience, I think. The poet is a nervous man; and as long as the muscles of his face were visible, his lips, eyelids, and mouth, were quivering so violently that I scarcely believed it would be possible to get an impression of them. He has a beautiful face for a scholar—clear, well-cut, finished features, expressive of great purity of thought; and a forehead of noble amplitude, white and polished as marble. His hair is black and curling (indicating in most cases, as Dr. Spurzheim remarked, activity of mind), and forms a classical relief to his handsome temples. Altogether, his head would look well in a picture, though his ordinary and ungraceful dress, and quick, bustling manner, rather destroy the effect of it in society.
