An incision was then made, and she was better during some time. But the disease soon made the most fearful progress. The inflammation appeared upon the outside, and she felt the most acute pains in her breast and throughout the whole length of her arm. She patiently endured the most excruciating torments. Having tried various modes of treatment without experiencing any relief, she finally consented to make trial of a new cure. During twelve weeks she saw no one except the members of her own household and the physicians, who sometimes said she was better and sometimes that she was worse; finally, however, fever set in, accompanied by all the signs of consumption. Perfectly aware of her condition, she prepared for death with resignation and devotion; she died during the night of the 30th of April. Her breast had burst open several weeks before. An examination was made after her death, and many causes for her last illness were discovered; but I cannot dwell upon these details.... In my opinion, and I followed the whole course of her malady, her chest was seriously affected in addition to the cancer. We have experienced an irreparable loss; I can scarcely endure life since our misfortune, and will never be able to think of the princess royal without the most bitter regret. I have not yet seen her husband; some say that he is ill, and cannot long survive his wife, but others speak of him as quite well: I know not whom to believe. I sometimes see their daughter, the Princess Mary, whom I love with all my heart, but whom I can only visit once during the week. She is charming, and already gives promise of a noble character. The princess royal, during her dying moments, left her under the protection of Elizabeth, the king's daughter and the prince royal's sister. Elizabeth is warmly interested in the young princess, and sincerely attached to her brother; she is a highly meritorious personage. May I beg you, madame, to continue toward me your previous sentiments of kindness, and to accept the expression of my unbounded esteem. L. MOSZYNSKA. The prince royal, Charles, survived his wife several months, and their daughter, still very young, was confided to the guardianship of Prince Charles's sister. When she reached a marriageable age, she wedded Prince Carignan, of Savoy, and their descendants are now allied to the reigning family of Sardinia. PETROLEUM.
