In my quality of Chevalier de St. Louis, I was invited to-day to a great dinner at Prince P----'s, in commemoration of the Saint's day, or the 'jour de fête' of the king of France,--I really don't know which. After it, I went to see the _Continuation_ of Don Juan at Drury Lane. 'Of course' the first act was laid in hell, where Don Juan immediately seduces the Furies, and at last even the devil's grandmother, for which offence he is forcibly ejected by His Satanic Majesty. Just as he reaches the picturesque shores of the fire-rolling Styx, Charon is in the act of ferrying over three female souls from London. While they are landing, Don Juan occupies the old ferryman's attention with changing a bank-note (for paper money is current in the infernal regions,) seizes the moment to make off with them from the shore, and conducts them back to earth. Arrived in London, he has his usual adventures,--duels, elopements, &c.; the equestrian statue at Charing Cross invites him to tea; but his creditors carry him off to the King's Bench, whence he is delivered by marrying a rich wife, in whom he at length finds that full punishment for all his sins which hell could not afford. Madame Vestris as Don Juan is the prettiest and most seductive young fellow you can imagine, and, it is easy to see, does not want practice. The piece amused me. Still more amusing was a new novel which I found on my table, the scene of which is laid in the year 2200,--not a very new idea, certainly. It represents the religion of England as once more Catholic, the government an absolute monarchy, and universal education so diffused, that learning is become the common property of the lower classes. Every artisan works upon mathematical or chemical principles. Footmen and cooks, with such names as Abelard and Heloisa, speak in the style of the _Jenaer Literaturzeitung_. On the other hand, it is the fashion among the higher classes, by way of distinguishing themselves from the 'plebs,' to use the most vulgar language and expressions, and carefully to conceal any knowledge that goes beyond reading and writing. There is some wit in this idea, and perhaps it is prophetic. The habits of life of this class are also very simple. Few and homely dishes appear on all their tables, and luxury is to be met with only at those of the servants. That air-balloons are the common conveyances, and that steam governs the world, are matters of course. A German professor, however, makes a discovery in galvanism, by which he is enabled to bring the dead to life; and the mummy of King Cheops, recently found in a pyramid which had remained unopened, is the first person on whom this experiment is tried. How the living mummy comes to England, and how horribly he behaves there, you may read when the novel is translated into German. 'Au reste,' I often feel like a mummy myself,--bound hand and foot, and eagerly waiting my release. _Nov. 5th._
