"I saw him a few nights ago [on or about New-year's Day, 1771; come back to us, from his Tour to Moscow, three weeks before; and nothing but galas ever since] at a Masquerade in the Palace, said to be the most magnificent thing of the kind ever seen at the Russian Court. Fourteen large rooms and galleries were opened for the accommodation of the masks; and I was informed that there were present several thousand people. A great part of the company wore dominos, or capuchin dresses; though, besides these, some fanciful appearances afforded a good deal of amusement. A very tall Cossack appeared completely arrayed in the 'hauberk's twisted mail.' He was indeed very grim and martial. Persons in emblematical dresses, representing Apollo and the Seasons, addressed the Empress in speeches suited to their characters. The Empress herself, at the time I saw her Majesty, wore a Grecian habit; though I was afterwards told that she varied her dress two or three times during the masquerade. Prince Henri of Prussia wore a white domino. Several persons appeared in the dresses of different nations,--Chinese, Turks, Persians and Armenians. The most humorous and fantastical figure was a Frenchman, who, with wonderful nimbleness and dexterity, represented an overgrown but very beautiful Parrot. He chattered with a great deal of spirit; and his shoulders, covered with green feathers, performed admirably the part of wings. He drew the attention of the Empress; a ring was formed; he was quite happy; fluttered his plumage; made fine speeches in Russ, French and tolerable English; the ladies were exceedingly diverted; everybody laughed except Prince Henri, who stood beside the Empress, and was so grave and so solemn, that he would have performed his part most admirably in the shape of an owl. The Parrot observed him; was determined to have revenge; and having said as many good things as he could to her Majesty, he was hopping away; but just as he was going out of the circle, seeming to recollect himself, he stopped, looked over his shoulder at the formal Prince, and quite in the parrot tone and French accent, he addressed him most emphatically with 'HENRI! HENRI! HENRI!' and then, diving into the crowd, disappeared. His Royal Highness was disconcerted; he was forced to smile in his own defence, and the company were not a little amused.
