Last night we went to the Wimpffens' grand official "ricevimento." All the street in front of the house was crowded just as it used to be in the old days--people coming close up to the carriages (going of course at a foot's pace) and peering in to see the diamonds. There was nothing like the display of carriages, diamonds, and liveries there used to be--many fiacres, and many uniforms. Countess Wimpffen looked very well in white satin, pearls, and diamond tiara, Wimpffen of course in uniform and his broad ribbon, Cenci (now Prince de Vicovaro) attached to the Court, was standing at one side of the Ambassadress presenting all the Court people. The Princess, his wife, stood near by looking very well, beautifully dressed, with diamonds and large pearl pendants. She was wearing for the first time her decoration of dame de palais. All the "White" Roman ladies were there. I saw quantities of people whom I knew. W. also begins to know the people. He thought the Roman women very distinguished looking, and the jewels splendid, particularly the pearls. We stayed quite late, and decidedly amused ourselves. I was rather interested in seeing when Madame de Wimpffen shook hands and when she merely bowed. When W. was at the Foreign Office and we had big receptions I was puzzled sometimes. My impulse was not to shake hands with the men. W. and Richard thought I ought to shake hands with all the Deputies, but that seemed a great undertaking and would, I think, have surprised them, as Frenchmen as a rule are formal, don't shake hands usually with ladies, but make rather a stiff bow, so I compromised by shaking hands only with those I knew.
