That may one day be the interesting question. But that is not the question of controversy at present: not that, but another; for Karl Philip, it would seem, is to be a frequent stone-of-stumbling to the Prussian House. The present question is of a Protestant-Papist matter; into which Friedrich Wilhelm has been drawn by his public spirit alone. KARL PHILIP AND HIS HEIDELBERG PROTESTANTS. The Pfalz population was, from of old, Protestant-Calvinist; the Electors-Palatine used to be distinguished for their forwardness in that matter. So it still is with the Pfalz population; but with the Electors, now that the House of Simmern is out, and that of Neuburg in, it is not so. The Neuburgs, ever since that slap, on the face, have continued Popish; a sore fact for this Protestant population, when it got them for Sovereigns. Karl Philip's Father, an old soldier at Vienna, and the elder Brother, a collector of Pictures at Dusseldorf, did not outwardly much molest the creed of their subjects. Protestants, and the remnant of Catholics (remnant naturally rather expanding now that the Court shone on it), were allowed to live in peace, according to the Treaty of Westphalia, or nearly so; dividing the churches and church-revenues equitably between them, as directed there. But now that Karl Philip is come in, there is no mistaking his procedures. He has come home to Heidelberg with a retinue of Jesuits about him; to whom the poor old gentleman, looking before and after on this troublous world, finds it salutary to give ear.
