=The Desire for Notoriety a Cause of Crime.=--Under the title _Luccheni Redivivus_ the London Lancet gives some interesting psychological data which have been obtained since the imprisonment of Luccheni, the assassin of the Austrian Empress. Twice since his trial and conviction he has attempted suicide. Within the last few days (May 13th) his moral condition has undergone a change confirmatory in a significant degree of the diagnosis which found vanity or megalomania at the root of his crime. The cantonal juge d'instruction in an attempt to ascertain if possible his associates in the crime, visited him in his cell and approached the subject with what seemed to himself due dexterity and caution. At once the previously downcast and abject creature brightened up, his eyes sparkling with gratified self-importance. "_I giornali riparlano di me?_" (So the journals are talking of me again) he exclaimed interrogatively. The judge disclosed the object of his visit. Luccheni thereupon dallied with his interlocutor, smiling at his reminiscences of the crime, assuming airs of reticence, even indulging in self-contradiction to tease if not torment his judicial antagonist. It was learned, however, that in the preliminaries leading up to the assassination he really had accomplices; beyond this nothing new was elicited from him. The point of chief importance, however, to be observed in this account is the large part which vanity and a desire for the widespread public attention which such crimes bring about plays in reconciling the criminal to his fate, and even leading to the commission of the crime in cases where the mental balance is very unstable. Hence this class of criminals should always be tried and punished with as little publicity as possible, not only because this policy deprives the individual of a show, with himself as the center, but also because every such public trial is liable to lead to the commission of similar crimes by other mentally unsound degenerates, who are sure to attend such spectacles whenever it is possible.
