In Spain, however, O’Donnell passes for an honourable man, who keeps his word when it is pledged, and is incapable of the baseness and peculation of which Spanish ministers have been too often guilty. Although formed and headed by the most popular man in Spain, and composed of men by no means unwelcome to the nation, the present ministry, brief though its existence yet has been, has not escaped censure for some of its acts. Of course, all the persons whom the revolution has upset, all the employés who are put on half-pay, all the friends of the polacos, the partisans of Sartorius, Bravo Murillo, Roncali, and other notorious ex-ministers, who now find themselves sunk in the slough of despond, are furious against the new order of things, and spare no pains to damage the government by propagating false reports and malicious inventions. On the other hand, the ultra-liberals, the republicans and clubbists, look upon the present men as a mere compromise, and declare that the revolution has been nipped in the bud, and has not gone half far enough. They have faith in Espartero, and discretion enough not violently to agitate, at least for the present, against his government; but here there are clearly the elements of two oppositions, one factious and reactionary, the other, by its impatience for progress, nearly or quite as dangerous. The most recent and the principal ground of complaint the latter party has found, is the intimation in a ministerial document published two days ago in the _Madrid Gazette_, and which preludes to a decree regulating the mode of convocation of the Constituent Cortes—that the government intends to admit no discussion as to the permanence of Isabella and her dynasty on the Spanish throne. There is at present a very strong feeling in Spain against the Queen personally, and against the race to which she belongs; and those who desire to see her compelled to abdicate, or dethroned by the vote of a National Convention—the proper name for the single popular chamber that is to assemble on the 8th of next November—do not perhaps sufficiently reflect on the difficulties to which such a measure would give rise. They are ready to remove, but are they prepared to replace, the erring daughter of the treacherous Ferdinand? My belief is, that were Isabella to-morrow to sign her act of abdication, it would be joyfully received by a large portion of the nation, but that discord would ensue as to who or what should replace her. During the latter days of the Sartorius ministry there were seven or eight candidates in the field for the premiership—as soon as it should be vacant. There have lately been nearly as many named for the throne, should the present sovereign quit it. First there is her daughter, with a long regency—probably that of Espartero. But this would only lead to fresh complications. The Princess of the Asturias is a puny, unhealthy child; besides which there are reasons, known to all, and which I need not
