_October 10th._--Arnim recently (date not noted) sent the Chancellor a rather lengthy statement of his opinion that Thiers should not be supported any longer, as he was only strengthening France for the benefit of Gambetta. He also hinted that we might give our support to others, in which case there would be plenty to make overtures to us. The Ambassador said he had severed his connection with B., who had shown himself quite incapable, but he was now employing another agent of the same description, who seemed in general to justify the confidence placed in his cleverness and powers of hearing. Prince Czartoryski had recommended to his political friends in the province of Posen, as Parliamentary candidate, the parish priest of Zduny, a man of strong clerical and nationalist sentiments, and a friend of Kozmian. Further, a French political agent, named Orlowski, was stationed at Dantzig, where he passed himself off as a commercial traveller. Samuel, the Chief of the French Secret Police, was now staying at Lunéville. Ladislaus Witkowski, a Jesuit, who spent several years in Rome, and who was made a Knight of the Legion of Honour on Czartoryski’s recommendation, had been sent by the Prince to the Grand Duchy of Posen, in order to promote an agitation among the peasantry. Witkowski was thirty-eight years of age, tall and stout, grows a beard, and wears plain clothes. He would probably put up at Kozmian’s. In Paris, he resided with the Jesuit, Jelowicki, who has recently paid several visits to Posen, and appeared to act as a channel for communication between Rome and the Grand Duchy. Witkowski might also have instructions from Samuel.
