Mr. Zzyx behaved beautifully at the very brilliant dinner given in his honor by Mrs. Cornelius Van Dyk at her town residence, the last red brick mansion of a remote period, except our own, still left standing in Washington Square. A dinner made more memorable than it otherwise would have been by the distinguished array of guests. Among them, Henry's beloved and revered old friend, the venerable Episcopalian prelate, Bishop William Buckingham, who had grown a bit queer in his dotage.

"A very novel idea on the part of our hostess," the Bishop remarked to Henry after dinner, in the smoking-room, while I sat by, listening and silent. "This sort of thing was done, years ago, at Newport, a monkey-dinner, as I recall reading about it, and the clergy and the newspapers made an awful row. Certainly times have changed when we can sit down to dinner with a man-ape without the flicker of an eye-lash. After this, I shan't be at all surprised to have one of my old parishioners invite me to dine with a white rabbit. Mrs. Van Dyk sets the fashions in New York, you know."

"After all," remarked Henry, "brutes and humans really belong to one great family by common descent."

"Hold your miserable tongue, sir!" the Bishop responded, perkily.

"Not until I've extended an invitation to your reverence, to attend the banquet the Exploration Club is giving for Mr. Zzyx on November thirtieth," Henry rejoined.

"The Exploration Club! How extraordinary!" the Bishop exclaimed. "The most exclusive club of its kind in the city. What's up?"

"Oh, just another revelation concerning Mars," Henry replied, nonchalantly. "You will come, won't you?"

"Do my best to oblige," the Bishop replied.

At that, I felt my ears pricking. I already knew that Henry, Olinski and McGinity, had something new about Mars up their sleeves, which was to be disclosed at the banquet at the Exploration Club. What it was, I had no idea. And I found out nothing that night. The conversation between the Bishop and Henry was cut short by the return of Mr. Zzyx and Niki, who had taken our Martian visitor to the lavatory immediately after dinner, to tidy him up a bit before we left for the opera.

A few moments later, we joined Mrs. Van Dyk, and her house guest, Lady Gwynne of London, in the drawing room. The other dinner guests had gone. Both were ready for the opera, Mrs. Van Dyk in a stunning ermine wrap, and Lady Gwynne in sables.
