It is impossible to imagine a greater contrast than that offered by the present mode of life of the Prince and Princess, and the splendor by which they were formerly surrounded. Prince ADAM was one of the richest proprietors, and possessed not one, but several, of the most magnificent palaces in Poland, and was accustomed from childhood to every comfort and luxury which wealth could devise. The house he now inhabits is as simple as possible; but he remains at home every Monday evening for the purpose of seeing his friends and countrymen; and his _salon_ is always crowded with the most learned men and most fashionable women in Paris. These weekly receptions are attended with but very little expense here, as tea and lemonade are the only refreshments it is the custom to offer. Prince CZARTORYSKI is a most venerable-looking man of about seventy. The expression of his face is habitually melancholy, but at times he is very animated in conversation. Like most Poles, he speaks low and very slowly. I remarked that he was particularly polite and attentive to young people, which in a man, who, from his various misfortunes and trials, can take but little interest in general society, is, I think, very striking. The Princess, who must be almost thirty years younger than the Prince, is very lady-like and prepossessing in her manners. She is much beloved by her _compatriotes_: her efforts to relieve those who are in distressed circumstances being unceasing. She employs all her leisure hours in embroidering; and her embroidery, which is more beautiful than any thing of the kind I have ever seen, is sold at a bazar, which is opened during the last week of every year; new-year's day being the time when the French make those presents to their friends which in England and in our country are made on Christmas day. All the ladies of the Princess's acquaintance of course contribute to her bazar; and those who are remarkable for their beauty or their talents, are invited by her to keep the stalls. * * * MRS. B----, whose son, a lad of about sixteen, is now engaged in attending the _cours de religion_, or religious lectures of M. COQUEREL, one of the clergymen of the Reformed Church of Paris, took me this morning to hear one of the lectures. M. COQUEREL is the nephew of the celebrated HELEN MARIA WILLIAMS, by whom he was educated. He is the most eloquent, and I believe the most learned, clergyman in Paris. I had been much pleased with his sermons, and was therefore very glad to have an opportunity of hearing one of his lectures. His class was composed of about thirty young men, of different ages, from sixteen to twenty-five. He has written a little book called '_Cours de Religion_,' which he makes use of in his lectures. The method he adopts is this: He reads a paragraph from this little volume, and then comments upon it, and explains or developes it, often relating interesting anecdotes suggested to him by the subject, or
