Analogous examples are innumerable. As I write these lines the papers are full of the story of two little girls found drowned in the Seine. These children, to begin with, were recognised in the most unmistakable manner by half a dozen witnesses. All the affirmations were in such entire concordance that no doubt remained in the mind of the juge d'instruction. He had the certificate of death drawn up, but just as the burial of the children was to have been proceeded with, a mere chance brought about the discovery that the supposed victims were alive, and had, moreover, but a remote resemblance to the drowned girls. As in several of the examples previously cited, the affirmation of the first witness, himself a victim of illusion, had sufficed to influence the other witnesses. In parallel cases the starting-point of the suggestion is always the illusion produced in an individual by more or less vague reminiscences, contagion following as the result of the affirmation of this initial illusion. If the first observer be very impressionable, it will often be sufficient that the corpse he believes he recognises should present-- apart from all real resemblance--some peculiarity, a scar, or some detail of toilet which may evoke the idea of another person. The idea evoked may then become the nucleus of a sort of crystallisation which invades the understanding and paralyses all critical faculty. What the observer then sees is no longer the object itself, but the image evoked in his mind. In this way are to be explained erroneous recognitions of the dead bodies of children by their own mother, as occurred in the following case, already old, but which has been recently recalled by the newspapers. In it are to be traced precisely the two kinds of suggestion of which I have just pointed out the mechanism. "The child was recognised by another child, who was mistaken. The series of unwarranted recognitions then began. "An extraordinary thing occurred. The day after a schoolboy had recognised the corpse a woman exclaimed, `Good Heavens, it is my child!' "She was taken up to the corpse; she examined the clothing, and noted a scar on the forehead. `It is certainly,' she said, `my son who disappeared last July. He has been stolen from me and murdered.' "The woman was concierge in the Rue du Four; her name was Chavandret. Her brother-in-law was summoned, and when questioned he said, `That is the little Filibert.' Several persons living in the street recognised the child found at La Villette as Filibert Chavandret, among them being the boy's schoolmaster, who based his opinion on a medal worn by the lad. "Nevertheless, the neighbours, the brother-in-law, the schoolmaster, and the mother were mistaken. Six weeks later the identity of the child was established. The boy, belonging to Bordeaux, had been murdered there and brought by a carrying company to Paris."[4] [4] L'Eclair, April 21, 1895.
