The character of the manifestations is as varied as are the phases of human emotion or the objects of human desire; but when the facts of a tragedy once come to light, the phantasm is always found to be significant of their important features. When a mother dies at a distance from her children, she is often filled with an intense longing to see them once more before she passes away. The result often is that she projects a phantasm into their presence which takes a lingering look into the faces of the loved ones, and then fades away. Two persons agree that whichever passes away first shall show himself to the other at or soon after the hour of death. The result often is that the agreement is carried out with startling fidelity. The object accomplished, the phantasm disappears forever. Another salient characteristic, which seems to be universal and which possesses the utmost interest and importance in determining the true source of the phantasm, is that it possesses no general intelligence. That is to say, a ghost was never known to have more than one idea or purpose. That one idea or purpose it will follow with the greatest pertinacity, but utterly ignores everything else. In the rare instances where the phantasm has been conversed with, it manifests perfect intelligence on the one subject, but pays not the slightest attention to any question pertaining to any other, not even to cognate subjects. This characteristic pertains to every form and phase of visions which are tangible to the objective senses. Subjective hallucinations are governed by different laws, and are not taken into account in this connection. M. Adolphe d'Assier, in his intensely interesting work entitled "Posthumous Humanity," mentions this peculiarity in a number of instances. Thus, on page 272 he says: "The shade only talks about its personal predilections, and remains deaf to every question outside the limits it has prescribed for itself. All the colloquies that have been gathered upon this subject resemble that of Bezuel and Desfontaine (1697), reported by Dr. Brière de Boismont. They were two college comrades, two intimate friends, who had sworn to each other that the first who died should appear to the other to give him some news about himself." Accordingly, the year following, the shade of Desfontaine appeared to Bezuel, and addressed him as follows:--
