Wednesday, January 19th, 1876.
We went to the Pincio, there were a great many people. The Duc de L——, son of the Grand Duchess M——, the emperor's sister, was there with Mme. A——, the wife of a Russian prefect. The Duc de L—— saw her and was captivated. Since then she is always with him. It is said that they are secretly married and live abroad. That is what people call having happiness. She had liveried servants and magnificent horses—suitable, I should think, for the niece of the Emperor of Russia.
