I regret very much that I have but a melancholy account to give you to-day of Lady Caroline’s health. Saturday she seemed in good spirits; but on that night she began to complain of pain in her side, accompanied with cough and shortness of breath. These symptoms are, I think, partly accidental, and may not continue; but should they, they will certainly give us great cause of alarm. There is another change, also; she is inattentive to what is going on. She speaks with difficulty, and seems unwilling to see many people. You may gather too plainly from all these symptoms the unwelcome news that her ladyship is getting worse; her sufferings she still bears with fortitude, and complains but little.
