The Expose of Spiritualism. The following extrn-t from a I'jrt-laiirl I'jrt-laiirl (Oregon) exchang, relating to Prnfesaor Bildwiu's fcXju.i.L, cannot fail to be of interest to our readers. Baldwin will appear at the theatre on Monday evening. Soata ain now he returTed, and parliee will Ju well to eecura them early, aa front seaU are desirable fur this entertainment : ' A committee of well known gentlemen gentle-men whs tirt selected to go ou the stage to see that there w.is no so-oalied so-oalied "trick" apparatus nor possible confederacy. Satisfied that everything every-thing was as represented, the entertainment enter-tainment began. Mr. Baldwin did all the wonderful feats performed by tho Paveupurt Brothers, not only as well, but better, and told no nonsensical ta'rs about awiataure I from the spirit laud. He was?ecurelv tied in a cabinet, and in a tew minutes min-utes was entirely free. A police officer manacled him ml It "darbies" and when the cabiuet was opened tho handcufla were not only off his hand, but were holding a pitcher and a chair together, clearly manifesting that in dome mysterious way they had been opened. Mr. Baldwin also distributed small" pieces of paper, among the audience, requesting thej recipients to write thereon brial 1 questions. Hie wife was then blind-. folded and thrown into a trance, and.i wonderful to relate, not only answered j the questions that had been writ- I ten, but alo- told the -questions! verbatim. When wo conaidcr that the writers of the questions kept the paper ou which the interrogatories were inscribed, eecretly and securely, not letting them out of their own hands, tbe solution about bow Mrs. Baldwin could know every thine about them becomes considerably mora ditlicuit than the "pous ai-' norum" to the nverage schoolboy. The Katie King mystery was also given by Mra. Rildwin; and if ihc eastern Kutio went through all the preliminary tying that our Oregon apparition did, wir do not wouder at the ejlocl it had upon the mind ol intelligent Robert Dale Owen.
