We make no apology for anticipating here the arrival of his highness at Limerick, because, by showing in the outset the mistake that Mr. O'Connell made between the titles of Prince de la Moscowa and Prince Muskau, we establish at once the identity of Goethe's "unprejudiced traveller," and a "right-minded" and "decorous" terminater of _affaires de cœur_--of whom many of our readers have had some personal knowledge--and whose imposing mustachios are still fresh in our own recollection. The cold nights of November do not more surely portend to the anxious sportsman in the country the approach of woodcocks, than do the balmy zephyrs of May foretell the arrival of illustrious foreigners in London; each succeeding season brings its flock of princes, counts, and barons, who go the ordinary round of dinners, assemblies, concerts and balls; yawn each of them one night under the gallery of the House of Commons; one day take their position on the bench at the Old Bailey; visit the Court of Chancery; snatch a glimpse of the House of Peers; mount St. Paul's; dive into the Tunnel; see Windsor; breakfast at Sandhurst; attend a review on a wet morning in Hyde Park; dance at Almack's; try for an heiress--fail; make a tour of the provinces; enjoy a battue in Norfolk; sink into a coal-pit in Northumberland; admire grouse and pibrochs in Scotland; fly along a rail-road; tread the plank of a steam-packet, and so depart,--"and then are heard no more." Such was this Prince Puckler-Muskau; and such were his qualifications and opportunities for depicting that "strange insular life which" (according to the clear and consistent summary of M. Goethe) "is based in boundless wealth and civil freedom, in universal monotony and manifold diversity--formal and capricious, active and torpid, energetic and dull, comfortable and tedious, the envy and the derision of the world!" His first letter, addressed, as all his letters are, to his "dear Julia,"--(that is to say, no doubt, his highness's consort, Princess Puckler, to his alliance with whom, we believe, he owed his princeship)--is dated Cheltenham, July 12, 1828; and the first observation which his highness is pleased to make upon his arrival at that popular watering-place is one of a mixed character, political, statistical, and philosophical, whence may be derived a tolerably fair estimate of his highness's accuracy and knowledge of "things in general." He is describing to his "dear Julia" the nature and character of the distress amongst the lower orders in England, and its causes and origin.
