DRESDEN, SEPTEMBER 19th (Excellency Hyndford just recovering from his colic, in Breslau), Kur-Sachsen, after many waverings, signs Treaty of Copartnery with France and Bavaria, seduced by "that Moravia," and the ticklings of Belleisle acting on a weak mind. [Adelung, ii. 469, 304, 503.] His troops are 20,000, or rather more; said to be of good quality, and well equipped. In February last we saw him engaged in Russian, Anti-Prussian Partition schemes. In April, as these suddenly (on sight of the Camp of Gottin) extinguished themselves, he agreed to go, in the pacific way, with her Hungarian Majesty for friend (Treaty with her, signed 11th April); but never went (Treaty never ratified); kept his 20,000 lying about in Camp, in an enigmatic manner,--first about Torgau, latterly in the Lausitz, much nearer to the ERZGEBIRGE (Metal-Mountains), Frontier of Bohemia;--and now signs as above; intent to march as soon as possible. Is to have Four Circles of Bohemia, imaginary Kingships of Moravia, and other prizes. Belleisle has tickled that big trout: Belleisle could now have the Election as he wishes it, would the Electors but be speedy; but they will not, and he is obliged to push continually. "Moriamur pro Rege nostro Maria Theresia," IN THE POETIC, AND THEN ALSO IN THE PROSE FORM. PRESBURG, SEPTEMBER 21st. This is the date (or chief date, for, alas, there turn out to be two!) of the world-famous "MORIAMUR PRO REGE NOSTRO MARIA THERESIA;" of which there are now needed Two Narratives; the generally received (in part mythical) going first, in the following strain:-- "The Queen has been in Presburg mainly, where the Hungarian Diet is sitting, ever since her Coronation-ceremony. On the 11th September [or 11th and 21st together], the afflicted Lady makes an appearance there, which, for theatrical reality, has become very celebrated. Alas, it is but three months since she galloped to the top of the Konigsberg, and cut defiantly with bright sabre towards the Four Points of the Universe; and already it has come to this. Hungarian Magnates in high session, the high Queen enters, beautiful and sad,--and among her Ministers is noticeable a Nurse with the young Archduke, some six months old, a fine thriving child, perhaps too wise for his age, who became Kaiser Joseph II. in after time.
